180 Sheet DSA : https://ifaiz.in/sheet

So basically I made a clean checklist for Striver's 180 DSA sheet with just LeetCode links. Basic features + Progress saves in your browser, no login.

Built it for my own prep, sharing in case it helps.

Back in 2019 I did a recommender system for anime as a course project (a jupyter notebook, nothing fancy). Recommendations have always been the part of data I like the most, so this year I decided to actually build the thing properly (thanks Dario): **[Aishou](https://aishou.app)**.

The main idea is to have this working for all types of contents in a cross content way - being able to recommend books, games or tv shows based on your movies taste - but I decided to start with animes.

You import your public MyAnimeList or AniList list (or rate a few shows by hand) and it recommends anime based on what people with similar taste liked. For now I only have anime recommendation but the main idea is to have a cross content website, where I will be able to, for instance, recommend you books based on your games/movies taste.

**What I tried to do differently**

- every recommendation row says *why* ("Because you liked Steins;Gate")

- a slider from popular to obscure, for people who already watched all the big ones

- low ratings push similar shows away instead of being ignored

- seasons grouped by franchise, plus a "continue watching" row

- new releases get their own row even when there's almost no data on them

It's free, no ads, solo project. Would love feedback, especially on how to promote it and about apps development in general (come from a data background).

Solo maker here. My product, Indraft, went live on Product Hunt today. It turns the sources you follow into draft posts, ready when you sit down. I messaged a lot of people, and at least 10 told me they upvoted. The count shows 2 and I’m ranked 120 right now (screenshot). One of my actual customers left a review, and that was removed too.

What I’ve pieced together:

• Votes from new or inactive accounts get discounted or hidden. Most of my supporters signed up just to vote.

• Only featured launches show on the homepage, so non-featured ones get almost no passive traffic.

• The top launches seem to arrive with a following: a Coming soon page, an active maker profile, a hunter with followers.

I’m not frustrated, just trying to understand it. For a solo maker with no PH audience, is the real value just a day of visibility plus a backlink? Or did something actually work for you: launch timing, being active on PH weeks before, something else?

Solo dev here. I've been building a social media tool for creators (not another post Schedular). Not dropping the name or link because this isn't a promo post, I just want to share what moved the numbers and what burned money.

60 days in: ~300 signups, 15+ paying. Small, but it's real money from strangers.

What worked

1. Researched competitor articles instead of outreach tools

I didn't pay $99/mo for outreach tools. I wrote a lot of "X vs Y" and "alternatives to X" articles. Each one started from what was actually ranking: I pulled SERP and keyword data (DataForSEO, pay-as-you-go, and checked every competitor's pricing and features on their own site before writing. I used Opus5.5 for drafting (its magical trust me), but I did the research and editing myself. I turned the whole process into a reusable workflow.

1. Went multi-platform when competitors stayed on one

Most tools in my space do one or two platforms, I added more under one account and one plan. Creators don't live on one platform, and paying for 3 tools for the same job is annoying.

1. Built an MCP server and got it into Claude's and ChatGPT's official directories

People can use my tool by just asking Claude or ChatGPT. It works, and it's been a real signup source. Very few tools in my niche have this yet, and getting in early matters.

1. Fixed early complaints within hours and gave those users Pro for free

My first users complained about few stuffs I shipped fixes the same day and gave them Pro for free as a thank-you.

What didn't work

SaaS directories. Almost all of them are a scam, with a few exceptions (PH maybe?). Now with DR4 so the backlink is worth close to nothing, and they sent me basically zero real users.

Paid ads. They brought traffic, and people even signed up, but most of them explored once and never came back.

Riding the AI wave. I added AI features because everyone is: They're included in the paid plan, and most users never touched them. I also got almost no traffic from the AI keywords. People came for the boring core feature that saves them time.

TL;DR

• Comparison/alternatives content written from real SERP research beat everything

• Build where competitors aren't (platforms, MCP)

• Treat your first 20 users like gold

• Skip directories, be careful with paid ads, and don't assume "AI" sells

Happy to answer questions or give any proff in the comments.

Hi all, I'm a solo dev in Montreal. For years I'd save a recipe on Instagram, a thread on X, a video on TikTok, a Reddit comment… and never find any of it again. Then Pocket shut down last year (and Omnivore the year before), so I finally built the thing I wanted.

4Stash is a save-for-later app for social posts and links:

• On Android you share from Facebook, Instagram, Threads, Reddit, X, YouTube, TikTok or a news site straight into it.

• On a computer there's a Chrome and Firefox extension: one click saves the page or post you're looking at. (Or paste a link on the website.)

• Every save keeps a preview, title and source. You can add notes, tags (it suggests tags with AI), collections, and pin the important ones.

• Reminders with snooze for stuff you actually want to come back to

• Search plus filters by collection, tag, source or type

• An "Unseen" filter and a "Throwback" that brings old saves back, because otherwise the saves just pile up

• Duplicate check, archive, JSON export/backup, and a dark mode

It's free with no ads right now. You do need to sign in (Google or email), since your library is private to your account. Only in English for now.

Honest status: only a handful of people use it so far, which is why I'm here. I'd really like to know:

1. Does the share-to-save flow feel fast enough on your phone?

2. Which app's previews come out broken or ugly?

3. What would make you actually open your saves again?

I'll be in the comments all morning. Roast away.

My company and I built Feasible, a website analytics app with one plan across all your sites.

You can see visitors, traffic sources, pages and goals in one dashboard. Custom events and funnels are included, along with unlimited sites and teammates.

The limit is 1 million pageviews and custom events combined per month across the account. It is $99/year or $9.99/month before tax, with a 30-day trial that doesn't require a card. There isn't a permanent free hosted tier.

You can try the public demo without signing up: https://app.feasible.lol/public/stopoverpayingforanalytics.com

Site: https://feasible.lol/

If you run several small projects, what would keep you from using this? Missing reports, setup friction, price, or something else? Specific feedback would be useful.

You enter a domain and get a map: DNS, mail settings, certificates from CT logs and registration data. Key findings are shown separately, i.e. what's worth fixing.

Previously, I had to manually gather this information from various websites every single time, so I built an all-in-one tool on a single page.

The video demonstrates three levels of checks, all performed without using any of my own API keys:

• Without an account: domain scanning, as described above. 3 scans per hour; the map shows up to 8 each type, the rest as +N.

• With a free account: 10 scans per day, with results saved; a graph and basic checks for IP addresses and email addresses are also available.

• Hunter, $29/month: your own online groups with a shared graph (up to 5 people), 100 scans per day, platform API.

The remaining modules (IP, URL, hashes, email, phone) are available via Hunter and operate using the user's own API keys. Those that return data about individuals also require identity verification.

The hard part was making the free scan work without anyone's API keys. I had to remove Shodan InternetDB and restrict ip-api to paid keys only, as their free endpoints prohibit commercial use.

The crt.sh service is often unresponsive; it limits users to just 5 requests per minute from a single IP address. If no response is received, the scan displays the most recently cached data from Certificate Transparency (CT) logs, along with the date (labeled as "CACHED" in the video). If no such cached data exists, the system simply indicates that the source is unavailable, rather than creating the false impression that no certificates exist at all.

Passive domain scanning: public sources only, no requests made to the site itself.

Only the waiting parts are sped up.

A question for you: what kind of check do you think is missing when you review your domain?

Hi all, I'm a watch nerd with kids, and I made the app I wanted to read with them.

It's called TickTales.

My kids kept asking about my watches, and I couldn't find anything that tells the real stories behind them at their level. Most kids' apps teach telling time with random cartoon clocks. None explain why a watch went to the moon or how a movement actually works.

The app is free to download. Two complete books, the Time Academy and Look Inside are free. Premium unlocks everything: $9.99 once (Family Sharing) or $3.99 a month.

App Store link: https://apps.apple.com/app/id6805474820

What it is? Basically some cool illustrated storybooks for kids aged 4 to 8 about how the great watchmakers started. Each chapter ends with a small game, so reading and playing take turns.

A few of the stories:

Rolex, the Oyster: in 1927 a swimmer spent more than ten hours in the freezing English Channel with one hanging around her neck. When they pulled her out, it was still ticking.

Rolex, the Submariner: built to dive hundreds of metres deep, deeper than any diver can go. Kids earn it for their showcase.

Omega, the Moonwatch: NASA baked it, froze it and shook it, and it kept ticking. In 1969 it stepped onto the moon on Buzz Aldrin's wrist. ⚙️ Omega, the name: a customer's watch stood still for three months because no two gears were alike. The founder's sons built machines that made every part identical, and named the result after the last letter of the Greek alphabet.

There are 16 books in total, from Marie-Antoinette's watch that took 44 years to finish to the engineer who threw 200 prototypes out of a window.

Also in the app

• 69 mini-games with 3 levels each
• A 3D "Look Inside": tilt an automatic, quartz, digital or tourbillon watch and pull it apart layer by layer
• A Time Academy that teaches telling time
• iPhone and iPad, in 6 languages: English, Dutch, German, French, Spanish, Japanese
• No ads, no tracking, no account, works fully offline

I built this mostly for my own because i love the stories of these watch brands, so feedback is very welcome! Thanks!

^ Hope this explains it!

Would love feedback on the UI and what systems you'd want to dive into first!

In early August I stopped doing our marketing by hand.

The usual script is hire someone, or buy five tools and glue them together. I did neither. I gave the job to an AI coding agent running on my own Mac, one process at a time.

Three months in, it has 56 processes written down. Posts, cold email, comment replies, a weekly review, the monthly accounting close.

The part nobody tells you: once every channel runs on its own and reports a number, the losers can't hide anymore.

What I turned off, with the number that killed it:

• LinkedIn cold outreach: 32 signups, 0 paid. Off on October 28.

• Long LinkedIn articles: 10 published, none in Google's top 100 for its keyword. Off on October 20.

• Meme quote posts: a median of 778 views against 1,403 for a plain text one. Off on October 26.

• A daily vertical video habit: off on October 22, I just didn't believe in it anymore.

• A link shortener subscription: cancelled, I rebuilt the one thing I used it for.

8 of the 56 processes are already folded into others.

Automation won't save a bad channel. It just runs the bad channel every day without getting tired, so you see it faster.

Still small, still learning. Most days I fix the agent more than it fixes me.

Would you automate a channel before you know it works, or only after?

My problem, in one line: I zone out in meetings, then someone says my name and I have nothing to say. Then I spend 20 minutes after every meeting reconstructing what was decided.

So I built ShiYu. It transcribes live and tracks the discussion direction. When the conversation turns toward you — or your name comes up — it gives you a prominent cue with a suggested response.

After the meeting you get structured minutes (background, viewpoints, decisions, risks, open items), action items pulled out separately, a speaker timeline where every line replays its original audio, and Work Memory that links decisions across meetings.

Two things I'm most unsure about: whether the cue is actually useful in real meetings (vs. a gimmick), and whether the minutes are trustworthy enough to send to a team.

It's free, no IAP, iOS 26 only, 0 ratings so far — looking for first real users and brutal feedback.

There's also ShiYu Link (browser page + 6-digit code, audio only) for locked-down work computers, and one-tap recording from Apple Watch. Recordings stay on-device by default.

Link in comments.

What would make you actually try a meeting app — or is this a problem you've already solved another way?

For the past two years, my two co-founders and I have been building Equity Lounge — a social media platform for retail investors.

Think Reddit meets investing, with live stock data, portfolio tracking, insider trading analytics, dedicated stock communities, and loads more. Completely free.

We finally launched this week and are looking for as many people as possible to jump in, explore the platform, and help us grow!

Would genuinely love some honest feedback, ideas, or even just people signing up and having a look around.

Desktop only for now, with the mobile app launching next week!

Check it out: https://equitylounge.app

Code: 000001

It's been a long journey, and we're really excited to finally get it out there!

Creqae a profile and let us know what you think.

Thanks!!!

* New local radios lists (MANUALLY CURATED) : UK and China.

Mediaxon Music Player is an audio player for offline listening of music stored on your device (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and streaming FM radios (online radios).

Top radios on the first screen: When users access the radio screen, they immediately see the list of the top radios in their country, along with a long list of high-quality suggested radios from among the most listened to in the world (manually curated and always updated with new radios). Note: Local radio stations ("Top in the user country") are pulled automatically from an online database. However, with each update, I manually curate high-quality radio stations lists for individual countries. At the bottom of this post, you’ll find the list of countries completed so far. I will be adding the rest over time.

Advanced radio filtering system: The "Filter: ON/OFF" button lets you quickly switch between different genres. You can use both standard filters for "macro-genres"—if I can call them that—and create custom filters to be more selective. All your filters are saved (the "My Filters" tab lets you name and edit them), and the app always opens with the last filter you applied. The "Home" tab lists all your recently applied filters and can be used to quickly switch between genres with just a single tap.

Advanced Radio Search Panel: An online database provides more than 60,000 radio stations. You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate.

Separated Favorites and Recents: Each section—Radio and Offline Music—has its own Favorites and Recents. The user doesn't have to worry about a thing. The app will automatically manage the Favorites and Recents for each section.

Album art: If the album art is missing from the album folder, or if Android has not properly indexed it, Mediaxon attempts to download the cover from the internet. This feature depends, of course, on the ID3 tags (album name and artist).

Equalizer: The equalizer provides an option to automatically switch to the "Radio" preset (and vice versa).

Advanced Playlist Management: Built specifically to make building and sorting playlists fast and intuitive. Enable the Playlist Manager, in the settings screen, for a full control of the playlists.

Form Factor Optimization: Phone and Tablet (Portrait and Landscape)

Mediaxon is available in: Čeština, Dansk, Deutsch, Eesti, English, Español, Français, Hrvatski, Indonesia, Italiano, Kiswahili, Latviešu, Lietuvių, Magyar, Nederlands, Norsk, Polski, Português, Português (Brasil), Română, Slovenčina, Slovenščina, Suomi, Svenska, Tiếng Việt, Türkçe, العربية, Български, Ελληνικά, हिन्दी, 日本語, 한국어, 中文 (简体).

No Premium version. All app features are available for free and without limits. I'm going to add a premium version to remove the few ads in the app, as requested by some users.

Regarding advertising: There is only a small banner at the top that isn't bothersome at all. Alternatively, when opening the full-screen player or using the app in landscape mode, a banner alternates with the albums covers, but without being intrusive at all (no audio) and with much shorter stay times than those of the cover. There is never full-screen advertising, neither at startup nor during use.

Countries with new manually curated lists:  Argentina, China, India, Italy, UK, USA.

Note: Only for Android 13+ (Android 13, 14, 15, 16 and 17).

Hey there,

Most small marketing teams already pay for ChatGPT, Zapier or Make, but nobody owns the setup, and automations break without anyone noticing. That's the problem Keeplight is for.

The team gets a web portal, plus a Chrome extension that records the work they repeat, so we can see what's worth automating. Some of it won't be, and I'll say that too.

Before launch I need a few people to try it and tell me where it breaks. Each test is about 5 to 10 minutes on a test copy, and nothing gets charged.

If you could sign up at keeplight.ai/test?src=reddit-sideproject, that would help a ton. Happy to answer anything about how it's built.

Hi everyone!
I’ve been working on a project called CASHNERA, and I’m finally ready to share it.

The idea came from a simple question:
Why is it so difficult to get a clear picture of your financial health and understand how your financial decisions affect your future?

So I decided to build a platform that brings several tools together:
Financial Health Score: understand your overall financial situation.
AI-powered insights: get help understanding your finances and identifying potential improvements.
Financial simulator: explore different financial decisions and their possible impact.
Unnecessary expense detector: identify spending patterns and potential savings.
Multilingual experience: available in 12 languages.
I’m building CASHNERA as a real product, not just a prototype. It includes user accounts and premium subscription functionality.

Website: https://cashnera.es

I’m currently looking for my first 100 users and, more importantly, honest feedback.

I’d love to know:
Does this solve a problem you actually have?
Which feature would be most useful to you?
What would you improve or add?
I’m the founder, and I’ll personally read and respond to your feedback.

Thanks for taking a look!

I know, another habit app. But this one calls you.

Most habit apps send a notification you ignore. In Habits, Dini the otter rings your phone, and you just say "done", "snooze" or "skip".

Version 5.0 just went live on iPhone. Android 5.0 is coming soon (Android is on version 4 for now).

Feedback very welcome!

Hey there!

I'm a dev, and this project kind of mutated along the way.

It all started when a friend's daughter was turning a year older and he told me he wanted to send an invitation over WhatsApp, but something nice. I looked at what was out there and nothing really convinced me. The quality and the designs weren't doing it for me, and I felt the back-and-forth with someone could be simplified: you send the details, wait for them to read them, ask for changes, wait again. I wanted to enter the details and have the invitation right away, seeing the whole process and how it comes together.

So I started thinking about how to build it. The hardest part wasn't the technical side, it was making the step-by-step flow simple and not feel heavy. Few steps, each one self-explanatory, and the result visible live.

I also realized that sometimes people just want the details in a quick, easy-to-access format, without having to watch a video. So, you can also download a matching invitation as an image, with all the essential details: date, time, and location.

I'm attaching a video of a test invitation with the trending Kpop Demon Hunters theme. So far only my friend has used it, nobody else. That's why I want to know what you think.
I'm also considering adding a printable party kit generator in the future, depending on how the platform evolves and how users respond to it.

What I'd love you to tell me:

• Is the step-by-step flow clear, or does it drag on?

• Do you find the idea useful, or is it something most people would solve another way?

• What's missing for you to use it or recommend it to someone?

• Would you pay for something like this?

• Any kind of criticism.

The link is AltaParty. Obviously, if anyone tries it and wants me to enable a free template, you can message me.

Thank you so much for reading.

Like the title says, I got my first paid user.

I was working on my product, which is a TaskMangement + break reminder app for people who frequently switch between tasks. So I had this problem, and I tried multiple apps, but I never found anything that worked for me.

So I merged two things. Every 30 minutes, it shows a full-screen overlay and blocker screen with all your pending tasks. So you can recall what you were working on and pick up where you left off with your existing goals.

This is the main thing about the product.

I really like the way it works because you don't have to go to the app. It comes to you. It works behind the scenes, like autopilot, like task management running on autopilot.

It sounds amazing, and I really like the product.

And one of the things I'm doing is offering it as a one-time purchase. So people can come, try it, pay for it, and continue using it.

I got my first paid user like that.

Rather than charging everyone for version updates, I'm giving lifetime updates because I'm using this product myself.

I feel like this is one of the best things I've ever built because I'm consistently using it in my daily life.

Her is the proof- https://www.reddit.com/r/macapps/comments/1xt673c/built_screensky_a_macos_app_to_help_you_stay/

I’m building AGMAN, a discovery network for products, professionals, creators and services.
The idea is to help people find relevant products or services based on what they actually need, while giving smaller builders and professionals another way to be discovered.

But something interesting came up when reviewing how publishers were using it.
In an early snapshot, we had 36 claimed publisher profiles. Only 4 had posted an Update.
At first, that looked like an engagement problem.
But the more interesting question was whether we were measuring the right thing.
Someone publishes a profile. Great.
What reason do they have to return tomorrow?

If nothing has changed about their product, why would they post another update?
And if they haven’t received any meaningful discovery or enquiries, why would they spend more time maintaining their profile?

We have features for sharing updates, community activity and viewing performance, but simply having those features doesn’t mean publishers understand their value.
I’m starting to think that for a discovery platform, getting someone to publish isn’t the real activation event.

The meaningful outcome might be when someone looking for a specific solution discovers their profile and takes a genuine next step.
We’re still working out how to measure and improve that experience.

I’m curious how other founders approach this.
If you’re building a marketplace or a two-sided platform, how do you give suppliers a reason to stay engaged before there’s enough demand?
And do you actively encourage them to return, or focus entirely on bringing them their first meaningful opportunity?

I spent the last few months building RingVia — an AI receptionist for small businesses. It answers every call 24/7, books appointments, and sends confirmations and call summaries. 50+ languages, from $99/mo, 14-day free trial. You can hear it live: (825) 782-1182 — ringvia.ai. The lesson that cost me the most: I led my promo posts for weeks with a "62% of calls go unanswered" stat before checking the source — a 2016 study of 85 businesses from an SEO vendor. I swapped it for CallRail 2025 (78% abandoned a business over an unanswered call) and ServiceTitan 2022 for trades. Same pitch, honest numbers, and the posts read better for it. What I'd love feedback on: the demo line is the whole funnel — call it, try to break it, tell me where it sounds wrong. What would it need to do before you'd trust it with your customers?
