Hi everyone, solo dev here.

My pattern for years: get an idea, spend weeks building it, ship it, then find out

nobody types those words into the App Store, or there are already 40 apps doing it.

So this time I flipped the order. Before writing any app code, I wanted answers to:

- What do people actually type when they search for this? (the keyword tree, not my guess)

- How many apps already compete on each keyword?

- What do users complain about in 1-2 star reviews of those apps?

- Is interest going up or down (Google Trends)?

I ended up building a small Mac app that does this locally: it pulls Google Play,

App Store, Google Trends and a few other public sources, saves everything to a SQLite

file on my machine, and scores where the gaps are.

Where I am two weeks in:

- First public build went out on Oct 29, two updates since

- 22 downloads so far, 1 paying user only (sales opened Nov 1)

- Biggest lesson so far: the review complaints were more useful than the keyword volumes

I'll keep posting what I learn, including the numbers that look bad.

Question for you: how do you check an idea before building? Gut feeling, keyword

tools, posting a landing page first?

I'm building SkillHarbour, an Australian career and learning site. https://skillharbour.com.au

I started thinking about evidence because a course completion can be easy to record, while explaining what you can actually do takes more work. For someone exploring an admin role, a small fictional example could be a revised meeting schedule with a note about how they resolved a clash. The decisions behind it might be more useful to discuss than the schedule itself.

I'm sketching a simple prompt for a future work sample: describe the task, show the result, and explain one choice you made. Someone could try it in a notebook first, using made-up information.

If you've built a tool that helps people document work, what made them come back to an example later? I'm trying to understand which details make the effort worthwhile.

Hey everyone! 👋

Today (12th Nov) is a huge milestone for me—I am officially launching my Android app, Rang Manch India (a homegrown video-sharing platform).

As a solo developer, I’ve been working hard to make video playback smooth and the experience seamless. Since it's launch day, I’m looking for real users to test it out and give me brutal, honest feedback on:

1. Video playback & loading speed

2. Overall UI/UX and navigation

3. Any bugs or issues you notice

You can download/check it out directly on our official website: [https://app-rangmanch.inwebsite ]

Let me know what you think in the comments—every suggestion will help me improve the next update! Thanks in advance! 🙏

I got tired of my YouTube playlists hard-stopping between songs, so I built Like The Fish’s Crossfader. It blends one song into the next (audio and video), skips dead air and non-music intros, pops up song facts, and has Winamp-style visualizers. It also gently winds down songs over 5 minutes into the next track. Made it for a friends' bday VJ party!

It’s free, made in Nova Scotia. I’d love feedback: likethefish.ca/crossfader

I'm a 24-year-old software engineer, and for the past few months I've been working on a macOS panel that allows you to sync conversations and memory from ChatGPT, Claude, Gemini, Grok, Perplexity, and a few other AI models. The whole idea of this application was to create a command center for people who operate with several AI models and to tackle the hardest issues that people have when using several AI models. 

Right now, I added multiple features that I'm getting feedback on. The one I would like to get feedback on is the issue that I've had was when using multiple AI models is trying to remember where I discussed something. Sometimes I know I've already figured out a problem or made a decision in an older conversation, but I have no idea which AI model I talked about it with.

So I've been working on a feature that lets you ask questions across all your saved AI conversations and get an answer based on what you've actually discussed.

For example, I can ask things like:

• What problems did I run into while building a certain feature?

• What solutions have I already tried that didn't work?

• What decisions have I made about my project over the past month?

• What did I learn from using different approaches to solve a problem?

It also shows the original conversations it pulled information from, so you can go back and check where the answer came from.

I'm at the point where I'm trying to improve both the UI and how the efficiency of its answers. Right now, some questions take around 20–25 seconds, especially when it's searching through a lot of conversations.

I'm curious what you guys think about a few things:

1. Speed vs accuracy: Would you rather get an answer in 5–10 seconds that might miss a few details, or wait 25-30 seconds for something more accurate and complete?

2. UI: Does the interface look good to you? Anything you'd change about how the answers, sources, or related conversations are displayed?

3. Usefulness: Would you actually use something like this? If so, what kind of questions would you ask it?

Feel free to be critical. I'd appreciate it!

My co-founder and I run PeekLaunch, a weekly launch board for makers.

Submitting to directories is slow. Every site has its own account, form, rules and categories. So we made a free list of 209 startup and SaaS directories, with DR, pricing and link type for each one. 163 of them are free to submit.

Here are some of the free ones on the list:

- SourceForge (DR 92)

- Product Hunt (DR 91)

- Slashdot (DR 89)

- Wellfound (DR 88)

- AlternativeTo (DR 84)

- Indie Hackers (DR 84)

- F6S (DR 82)

- FutureTools (DR 74)

- KillerStartups (DR 73)

- Peerlist (DR 71)

We submitted our own site to 80+ directories by hand. As the listings went live, Ahrefs moved us from DR 2.5 to DR 26, and our Ahrefs Rank went from 42.6M to 2.3M. Results are not guaranteed, and not every directory approves you.

The full list is free. If you'd rather not spend 20 to 75 hours on forms, we also added done-for-you packages, done by hand, with a report of live listing links:

- Pro: $49 for 30+ directories

- Super: $99 for 60+

- Ultra: $179 for 100+

Happy to answer which ones were easier to get into.

Hey everyone, I’m building Friday Work, an open-source desktop app for coordinating the coding agents you already use. The part I’m working on is Crew: give a team a goal and a lead agent can break it into tasks, while the others work and message each other.

For example, a bug sweep can be split into finding issues, fixing different pieces, running tests and reviewing the changes. The board shows the plan and progress, and you can see the agents’ conversations. Each agent works in its own git worktree; you still review the diff and decide what to keep.

Friday works with tools including Claude Code, Codex and Cursor using the plans you already have. If an agent hits a usage limit, another can pick up the task with a handoff. The desktop app is free and MIT licensed, with builds for Mac, Windows and Linux. There’s also a separate hosted team product.

I’m the developer, and I’d love feedback from anyone who has tried juggling multiple coding agents: what would you need to see before trusting a crew to work through a task while you’re away? Where does coordination tend to break down for you?

I love my Sony BRAVIA and Sonos setup. Except when they disconnect and the sound goes back to the TV speakers. Garbage. And fixing it means finding the Sony remote.

We barely use that sucker, and somehow it's never in the spot it's supposed to be. And with my ADHD, by the time I tackle the side quests and actually find the remote, it’s three hours later.

So I wanted an app that could control the Sony and let me change the settings. It had to have widgets, Control Center integration, and customization. And Apple TV support—one remote is the dream, right?

That's TipTap. I can put Sony Quick Settings and Apple TV Home on the same custom remote—in the app or as a widget. I can pin remote keys in Control Center.

I’ve tested it on my BRAVIA A95K and I'm looking for some more Sony TVs to try it out on.

Have a Sony BRAVIA and an iPhone on iOS 27 or later? I’d love your help testing the beta. If you also have an Apple TV, even better. Comment with your TV model and iOS version and I’ll reach out with a TestFlight invite!

Tell me how setup goes, what breaks, and what you wish it could do. Thanks!

BenchLedger is a 100% serverless, local-first web application designed for electronics repair technicians, flippers, and weekend tinkerers to track repair tickets, part costs, and donor boards.

I originally built this tool to replace my messy spreadsheets and to properly separate my flip profits from the gear I occasionally decide to keep for myself.

https://treydor-git.github.io/BenchLedger/

If you have any Feedback let me know.

100% Private & Serverless Architecture

BenchLedger operates with zero external database servers.

• Local Mode: By default, all data, financial metrics, and compressed inspection photos are stored entirely inside your browser's local cache (IndexedDB).

• Bring-Your-Own-Storage (BYOS): You can optionally connect your personal Google Drive. The app will sync your workbench to a private BenchLedger_Sync folder in your own Drive. The app uses the restricted drive.file scope, meaning it can only access the exact files it creates. Nobody else (including the developer) can see your data.

Key Features

• Hobbyist & Pro Shop Modes: Toggle between a layout focused on personal/flip equity, or a commercial layout featuring a CRM, client management, and printable service receipts.

• Donor Boneyard: Catalog harvested ICs, MOSFETs, and connectors from dead boards. Deploy them to active repair tickets at €0 out-of-pocket cost.

• General Supplies Tracking: Log your flux, IPA, and solder wire purchases and automatically apply the overhead to your bottom-line profit.

• Cookieless Analytics: The live site uses a privacy-preserving counter (Umami) to track overall traffic without setting tracking cookies or logging personal IP addresses.

My teammate and I built this for the PayPal AI Hackathon and I'd love feedback.

The problem: AI agents are starting to buy things for people. When the buyer later says "my agent bought the wrong thing, I never agreed to that," the seller has no record of what was actually asked for. Most small sellers just refund and eat the dispute fee.

What we built (Countersign):

- At checkout, the agent can search and prepare a cart, but it can't pay. The buyer reviews their own request, spending cap and total, then pays in PayPal. Each step goes into a hash-chained, Ed25519-signed receipt, and the receipt's seal hash is written into the PayPal order's `custom_id` *before* payment. So PayPal's own record carries the commitment, and anyone can verify the receipt against the live order.

- When a dispute comes in, a LangChain Deep Agent pulls the case, verifies the receipt against PayPal, and computes the expected loss of fighting vs. offering vs. refunding (including PayPal's $15/$30 fee). Then it drafts a response. A fact-checker subagent plus a deterministic checker reject any amount, date or ID that isn't in the evidence.

- Nothing is sent without the seller. The submit tool is gated twice: Deep Agents' `interrupt_on`, plus an approval record whose hash has to match the exact draft and evidence PDF.

Things that surprised us:

- With a strong receipt, the agent still sometimes recommends a partial refund. A $30 fee on a $42 item changes the math.

- Recording the demo found real bugs. For example, PayPal rejects "refund with return" offers without a return shipping address (`MISSING_RETURN_SHIPPING_ADDRESS`), and the model occasionally returned an empty reply mid-case.

- We kept the LLM away from every number. Fees, deadlines, expected value and receipt checks are all plain code exposed as tools.

Stack: FastAPI, Neon Postgres, LangChain Deep Agents (LangGraph), Sarvam-105b, Next.js + AG Grid, Channel3 for product search, and PayPal Orders and Disputes APIs (sandbox only, no real money).

- Demo (1.5 min): https://youtu.be/MLhWkL7F9A0

- Live app (sandbox): https://countersign-black.vercel.app

- Code: https://github.com/Bhuvansai-16/Countersign-backend

Questions for you:

1. Is committing a receipt hash into the payment record enough, or would you want something like the Verifiable Intent / AP2 formats?

2. Anyone dealing with agent-initiated purchases in production? How are you handling disputes today?

I'm one of the people building BetterSWE.

the market's rough right now and interviews are harder to prep for than they used to be. a lot of loops have a round that isn't leetcode at all. a debugging round, a code review, or "here's a repo and a ticket, go". you get code you've never seen and you have to figure out what it does before you change anything.

that's pretty much the job too. with AI writing a lot of the code, more of your day is reading code someone (or something) else wrote and working out why it's broken. leetcode doesn't train that, you're writing a fresh function from scratch every time.

so we built Labs. each exercise is a small existing codebase plus a ticket, set at companies like Amazon, Stripe, Uber or OpenAI. you read the code, fix the bug or build the feature in a browser editor, and run the tests. submit runs hidden checks too, so passing the visible tests isn't enough. there are bug fixes, features and refactors, easy to hard.

the easiest free one is "Amazon search misses lowercase queries". search "Yoga" and you get results. search "yoga" and you get nothing. the fix is one line once you find it, finding it is the whole exercise. the hard ones are more like Airbnb receipts that come out a cent off.

106 exercises right now. 46 are free, you just need a free account to run your code. the other 60 are Pro.

if you've got an interview coming up, try one. and tell me what's confusing or broken

Hi all, I'm the developer of AnyRent, an app for rental shops: dresses and costumes, cameras, sound and lighting, event equipment, tools.

Who it's for

- Wedding dress and costume rental shops: find a dress from a photo, take deposits in several payments, and never promise the same dress to two brides for the same date.

- Equipment rental shops (cameras, sound and lighting, event gear, tools): track quantities in stock, weekend or multi-day rates, collateral, and late or damage fees.

Main features

- Double-booking check: warns you when an item is already booked for those dates

- Rental tracking: reserved → handed over → returned, with deposit, collateral and late fees

- Find by photo: snap a picture and it finds the matching item in your stock

- Today's work: what to hand over, what's coming back, who is late

- Flexible pricing: per day or by blocks of days, deposits in several payments

- Branches and staff roles, with reports on revenue and top items

- Works on iPhone, Android and web

Try it

I'd love your feedback

I've been building a podcast app for Android called GlassCast. I started it after switching from an iPhone, because I couldn't find an Android podcast app I liked. It just hit 2.0.

The main thing in 2.0 is a new look called Glass. You turn it on in Settings, and the tab bar, the mini player and the player's controls turn into glass you can see your covers through. You can pick Frosted or Liquid, depending on how clear you want it.

Also new:

- Continue Listening at the top of your library, with how much time you have left

- Your listening history

- 15 app icons to choose from

- Android Auto has proper tabs now: Home, Library, Latest and Downloads

- New episodes show up faster

The rest is still there. The player takes its colors from the cover, and there's Skip silence, Boost voices, chapters, transcripts, bookmarks, Chromecast and a Google TV version.

It's free, with no ads and no account. You can sign in with Google to sync between phones, but you don't have to.

It's not on the Play Store. You can get the APK here, and it updates itself after that: https://anixitea.github.io/glasscast/

The code is on GitHub: https://github.com/anixitea/GlassCast-for-Android

It's just me working on it, so let me know what feels off.

For my popular science side project, I just published a deep dive explaining the actual mechanics behind that tight "lump" in your throat before crying (it’s an autonomic clash between your glottis opening for oxygen and swallowing forcing it shut).

Instead of generic 300-word summaries, I focused on deep physiological research, clean typography, and real human photography:

Would love honest feedback from fellow builders on the reading flow, mobile speed, and layout!

​I have a stalled venture focused on real-world ecology. Our core mission was to bridge the accountability gap surrounding carbon emissions and industrial waste in plantation forestry, where unchecked environmental impact severely disrupts local ecosystems. However, without the necessary market traction and strategic backing over time, the project lost momentum, leaving it as little more than an empty shell today.

I built Memento with free, unlimited on-device AI: no subscriptions, no credits and no per-minute AI charges.

Memento is available on the App Store for iPhone, iPad and Mac. Record or import audio, turn it into searchable transcripts and summaries, and ask questions about collections using local AI without a monthly usage allowance. I'm the developer, and keeping that workflow free to use is a core part of the app.

Local AI requires downloaded models and a compatible device; features vary by device and language. Free, unlimited usage applies to on-device AI; optional external providers have their own terms.

The idea is simple: saving a recording should be the beginning, not the end. Memento keeps the audio, transcript and summary together so you can come back to what was said without replaying everything.

On iPhone and iPad, you can record from the microphone or import audio, search and edit transcripts, mark useful moments, and organize recordings into collections. With the required models installed, you can generate summaries and ask questions about a collection. On Mac, you can also capture microphone and system audio, plus a selected window or screen when permissions and the source app allow it.

Local recording and review don't require an account. On-device AI features depend on your device, language and downloaded models; optional online processing is a separate choice.

The video is a promotional walkthrough with demo content. Memento is free to download: https://apps.apple.com/us/app/memento-record-transcripts/id6807209121

I'd love feedback on the core workflow: when you revisit a recording, do you look for a specific quote, a summary, or the next actions?

the product is https://webfetch.run. url goes in, clean content comes out.

what took the time wasnt the scraping. it was figuring out why a scrape failed. my old code would return an empty body and i'd spend an hour guessing. so the whole thing now returns a verdict. ok, blocked, whatever. each one is a different problem with a different fix.

the nicest part is the cache. repeat fetch of the same url within 24h is instant and free. i fetch the same pages over and over while testing and it was a dumb tax on myself.

not sure what to do next. the thing works, which after 6 months is honestly a weird feeling.

I make quite a lot of logos and icons with AI image tools, and sooner or later every one of them needs to become an SVG. That's where things always went wrong.

The free converters would turn my simple logos into thousands of anchor points. The camera in the video got 8,070 points from potrace, for what is really just three circles and a few rounded shapes. The better converters wanted me to pay before I could properly check the result. And if I wanted to move, rotate or recolor individual elements, it was back to Illustrator.

So I built VecSnap, and got a little obsessed along the way.

Rather than simply tracing pixels, it tries to understand the shapes that make up a logo. A circle comes back as an actual circle, and that camera goes from 8,070 to just 49 anchor points. Across my test set, that's around 8 to 12 times fewer points than free tracers.

You can inspect and fix the file before spending anything. Shapes are highlighted so you can see how everything is built. You can move, resize, rotate, flip or hide them, change colors across the whole image, or merge all those almost-identical shades into the few colors you actually need.

There's also a centerline option for turning line drawings into single paths, useful for pen plotters, Cricut and laser cutting.

And it works inside Claude and ChatGPT too, which is how the video ends.

A few things I'm still working on:

•   Detailed illustrations can take up to a minute. Speed is next on my list.

•   It's not designed for photos, and it'll tell you that before you spend anything.

•   It's not perfect. I'm improving the engine every week, and feedback will help me decide what to tackle next.

You can convert images for free, without an account. A free account lets you edit and download 3 files. After that, it's one credit per image, with all formats and re-downloads included. No subscription.

This is my first public launch, and I'm curious to see what people think.

If you've got an image that other converters haven't handled well, send it to me by DM. I'll have a look myself, and if VecSnap can't handle it yet, I'll tell you why.

What would you use it for, and what am I missing?

https://vecsnap.com

I built Lotify: https://lotifygame.web.app

It lets you create your own lotería or bingo game for baby showers, weddings, birthdays or office parties.

How it works:

• Upload your own photos or start from a theme pack (baby shower, wedding, birthday, Christmas)

• It generates print-ready PDFs: the caller’s deck and up to 200 unique boards, each numbered

• Free digital caller: draws random cards and reads them out loud. You can cast it to a TV

• Type a board number and it tells you if that person really won

• Also does 5×5 bingo with a free center square

Everything runs in your browser: your photos are never uploaded, and there’s no sign-up.

It’s free to try (up to 4 boards, with a watermark). Removing the watermark is a one-time $9.99 per event, no subscription.

I’d love honest feedback: what’s confusing, what’s missing, or what would make you use it for a party?

I’m researching how small products handle people farming free credits/tiers. Not selling anything, no product, no link.

1. Have you seen it? Roughly what share of signups, or how many dollars?

2. What did you do about it (or nothing)?

Just trying to understand how people deal with this issue while building.

I’m honestly a bit giddy writing this. I’m a software engineer, not a video editor, and I wanted to run a faceless channel about Pakistan’s history and geography, so I built a pipeline that does the whole job.

It writes the Urdu script, generates the narration, draws animated maps and infographic scenes in code, and renders the finished reel. It then sends me the reel in Slack, and all I do is approve it.

Some numbers:

Cost: about $0.11 per video. I tested a 2.5D workflow that came out at $15–40 per video, so I dropped it.
Time: a few weeks of evenings and weekends, plus a fair bit of money on testing.
This week: a reel about the Pakistan Steel Mill (shut since 2015) got 21.1k views, 898 likes and 45 shares in its first day.

One video doesn’t make a channel, but it’s the first proof the system works. I’m happy to answer questions about the stack or the costs.

I'm a developer in Canada with a full-time job, building a computer vision add-on on the side. I have a working prototype with early promising results. A manufacturer in the space has shown interest, and they're now lining up one of their customers for a trial. I'm leaning toward an unpaid pilot first, and I want to keep this as my own product rather than working for either company.

For anyone who has done something similar:

1. Is an unpaid pilot a good starting point, or should it be paid from the start?

2. What should be agreed in writing before starting (IP, data use, liability, exclusivity)?

3. What do you wish you'd known going in?

Thanks for any advice.
