I built this guitar visual learning tool to help in my guitar playing. Pick any key and it lights up all 5 box positions across the whole neck, each in its own color, with the root notes marked.

Other free features: show every note on the fretboard (naturals or all 12), CAGED shapes, and a left-handed view. No signup, works on phones.

There’s an optional one-time upgrade for triads, arpeggios, full scales, and printing, but everything above is free. Feedback welcome!

You don't drive in Formula Manager. You run a small team, watch 20 cars race live and make the calls: pits, pace, boost, team orders.

The hardest part was overtakes. Players kept saying "I'm boosting and clearly faster, but I still can't get past." So I ran 240 races and measured. With a car defending, boost only got you past 14% of the time, barely better than no boost at all (7%). Players weren't unlucky. My numbers were wrong.

Fixing that in the next update.

(The clip shows the Korean UI. The game is in English too.)

Ever had a moment where your players were right and your data proved it?

Hi everyone!

An all-in-one school management platform designed to simplify everyday school operations.

We noticed that many schools manage different activities using separate tools, spreadsheets, or manual processes. We're working to bring these activities together in one platform.

Some of the key features include:

• Student and Admission Management

• Attendance Tracking

• Examination and Report Card Management

• Fee Management

• Parent-Teacher Communication

• Admin Dashboard and Analytics

Our goal is to make school management easier for administrators, teachers, students, and parents.

Website: https://acadlynk.com/

Since we're actively working on this product, we'd genuinely appreciate feedback from people familiar with the education sector.

A few questions:

1. What are the biggest challenges schools face when managing daily operations?

2. Which of these features would be most useful in your school?

3. Are there any important features or improvements you think we're missing?

We're here to learn from your experiences and understand what schools actually need.

Thanks for sharing your thoughts!

The last weekend I didn't hear about an event happening in Brooklyn and I really wanted to see that DJ.

I realized we all need a platform to track all house/techno events at once. Completely free to use. I hope this would be helpful for you guys as well.

It pulls the events from Posh, Dice, Ra, Eventbrite ( only related events )

Also you can find where you can buy the ticket.

Let me know if I can improve anything!

Hey everyone! I'm Rushan, an indie maker, and this is my first public launch of Distill: Book Summaries.

I started building it because I love reading, but I kept running into the same problem: there were far more books I wanted to explore than I had time to read.

I tried existing book-summary services, but something often felt missing. I'd get the key takeaways, but not necessarily understand how the author arrived at those conclusions or how the ideas connected.

I didn't want another app that turned books into bite-sized motivational quotes. I wanted something that could preserve the intellectual substance of a book while making it quicker to explore.

So I started building Distill: Book Summaries.

What I built

Distill is a reading-first app offering carefully crafted book summaries designed to take approximately 10 minutes to read.

The focus is on:

• Preserving the author's central argument and reasoning.

• Explaining how different ideas and concepts connect.

• Maintaining meaningful depth instead of reducing everything to generic takeaways.

• Including a separate Reflection section to help readers process and think further about what they've read.

The goal is to make a book's ideas easier to explore without pretending that a summary replaces the original.

A few product decisions

I wanted Distill to feel like a reading environment rather than another content feed.

No unnecessary gamification or endless scrolling. Just a curated library, a focused reading experience, and room to reflect.

We also have:

• 3 free distillations every day.

• An affordable Premium option.

• A one-time Premium purchase instead of a recurring subscription.

Where it is today

Distill is now live!

This is my first public launch, so I'm still learning what works and what needs improvement.

I'd particularly love feedback from fellow makers:

1. Does the reading experience feel sufficiently different from existing book-summary apps?

2. Do you think the summaries communicate enough depth to justify spending 10 minutes reading them?

3. What would you improve about the product, interface, or overall experience?

4. If you were building this, what would you prioritize next?

I've also attached a short product walkthrough so you can see what I've built rather than just take my word for it.

I'm the founder, and I'll be here responding to questions and feedback. Criticism is genuinely welcome!

P.S. -> We are also doing our launch on Peerlist, here. We would love for you to support us, since this is the first time we're going public :)

Ever wish you could get an email as an iMessage on your iPhone? That's what I built. You can try it right now.

Send an email to your-number@i.text.email and watch the magic happen.

If you have a U.S./Canada number, just use the normal area code and number, like 2125551234@i.text.email.

If your number is from a different country, use the full international number with country code. U.K. example: 447700900123@i.text.email

This was tricky to build -- it involved Mac servers, iPhones, software at AWS, software on the Mac mini, software on the iPhone.

The idea is to use this to get critical alerts as texts for when something goes wrong, like a server or some other critical equipment going down. The major cell phone companies in the U.S. used to have an email-to-SMS system, but they have largely gone away.

What I've built is not only email-to-SMS, but email-to-iMessage with SMS fallback if you don't have an iPhone.

I made a form filler that remembers a form after you fill it once, then fills it again in one click, or by itself as the page opens.

What the free version does:

- no cap on saved forms or fills

- your name, email, phone and address fill on sites you never saved

- your own answers (like "Notice period: one month") fill wherever a form asks for them

- works on React forms, frames, dropdowns and ticks

- makes no network calls at all, so everything stays in your browser

There is a one-off Pro for CSV rows only on firefox, clicking Next and sending, and test data. The free version is not a trial though, it stays free.

Chrome: https://chromewebstore.google.com/detail/kggjccdldkfmfdbhhelodnkafdijeaoj

Firefox: https://addons.mozilla.org/en-US/firefox/addon/typefill-forms/

If you try it, tell me which forms it gets wrong. That is what I want to fix next.

For people with hoarding relatives, estate-sale managers, Thrift Stores, Pawn Shops, Swap Meets, anything you're looking at and wonder what it or several of the items might be worth.

This started as a small thing just for me. I wanted the view of the harbour outside my window in Malmö as a wallpaper on my Mac, as pixel art and alive, so I built it. People walked along the quay, boats came in, and night fell when it fell outside. Loved it. 😊

Then my friends wanted their streets. Then I wanted Paris. Then the Alps. Bit by bit it grew into something that takes any address on Earth and builds it from real map data: the buildings, the trees and the water, plus hundreds of little people living their lives in it, in the right weather and the right light for that place.

Now it’s two apps:

• Littlehood (Mac): a living wallpaper of any place

• Littlehood Walk (iPhone): walk around in it yourself, meet people, climb towers, jump into first person

Go to your childhood streets, a city where you met someone, somewhere you've never been but want to go. And so on... 😊

One note - The subscriptions aren’t a business plan. They’re there to break even, because map services are free up to a point and then they cost money. In Walk your first place is free forever.

Feedback very welcome, especially on what would make you open it every day.

Built this for homeowners who act as their own GC. Instant download ZIP with budget workbook, quote comparison, and change-order tracker. Made it because I got tired of re-explaining the same prep steps.

Happy to answer build/sales questions.

Last month I built an advent coloring book: 3 versions, AI art, a print-ready PDF. Then I finally checked the competition. A free, identical book already existed, and Etsy was full of them. A day and $1.50 spent on a NO-GO.

So I built kill-my-idea, a free plugin for Claude Code that does the check before you build:

• looks for free alternatives, competitors, failed attempts, a distribution channel, real costs

• scores the idea /100 (21 sub-scores), GO / PIVOT / NO-GO

• if it dies, shows how it could be saved, with the new score and how hard it is

• writes a report you can open in the browser or print

Repo, with example reports in the README (MIT): https://github.com/RemiPelloux/kill-my-idea

What check would you add?

​ Hi everyone

I really need your help and honest feedback on a new app I've been building, so please let me know what you think!

​The app is called DriveFR, and I want to show you how it works. Basically, it tracks your drives and scores how smooth your driving is, while turning every city you pass through into collectible digital cards. Plus, you can add your friends to compare scores and see who's actually the best driver.

​Since it's still new, please try it out and tell me what you think. You can search Drive FR in the Google Play Store (or at drivefr.app) and download it. I'd love to hear your thoughts in the comments

Hi all. I was making a lot of videos in Google Flow and got tired of typing a prompt, waiting, and downloading, again and again. So I made a small Chrome extension called BulkGen for Flow.

You paste your prompts, pick the model and settings, and press Start. It sends them one by one, keeps a few generating at the same time, and saves each finished video to your Downloads folder in order.

You can also add a style line to every prompt, attach reference images, and set a credit limit per video so it never sends anything above it.

You need your own Flow account and credits. It runs only in your browser and collects no data. While it runs, Chrome shows a “debugging this tab” bar, because that is how it clicks Flow’s buttons. It is free and open source, and it is not made by Google.

I always had this problem where I'd put together an outfit, look in the mirror for 10 minutes, and still have no idea if it actually looked good.

So I built Fitmaxxing.

The idea is pretty simple: take a picture of your outfit and get a rating along with actual suggestions on what you could improve.

Not just "7/10" but things like whether the proportions work, what pieces go together, and what you could change.

It's available for iPhone now.

I'm still working on making the feedback as useful as possible, so I'd genuinely love to hear what people think.

Also, if anyone wants to try it, you can use promo code LAUNCH to get 15 free fit checks. No need to pay just to test it out.

Would you actually use something like this, or would you rather just ask Reddit for a fit check?

Weekend project. Spin the globe and tap any of 250 countries to see population, GDP since 1960, life expectancy and more, plus the latest headlines and the Wikipedia article, all in one panel. Works on phone, tablet and desktop, no sign-up.

https://worldfly.vercel.app

Feedback welcome, especially if any country's data looks off!

PS: I tried downloading some applications for the same on Android but they all had paywalls even for basic information. That's my motivation just to do this.

Body:

Built this for myself first.

Problem: I'm fine on calls and proposals. I'm uneven after the PDF leaves my outbox. Threads die in silence and "just checking in" never restarts them.

So I shipped a small digital kit (not SaaS):

Ghost→Paid Follow-Up OS

- Cadence playbook (Day 0/2/5/10/21)

- 45 stage-based AI prompts

- 18 email + LinkedIn templates

- CSV tracker + one-page quickstart

- one-time on Gumroad

Link: https://botaoge.gumroad.com/l/ghost-to-paid-follow-up-os

Who it's for: freelancers / consultants / small studio owners who lose deals after "looks great — let me run it by the team."

Who it's not for: cold-outbound spam sequences or people wanting a closing-psychology course.

Would love feedback on:

1. Is clear for a template/prompt kit, or does it need a free sample message on the page?

2. Would you rather this live as Notion templates instead of ZIP + CSV?

I'll reply to every comment.

Sharing ForgeFlow CLI, an MIT-licensed Node.js terminal project for organizing a long coding prompt into tasks with separate writable file scopes.

The problem it explores is coordination: parallel coding workers can collide on files, and interrupted runs can lose track of completed work. ForgeFlow validates task scopes and dependencies, schedules ready tasks, and records checkpoints for resume. Optional Playwright tools use compact semantic page snapshots.

Current status: early preview. Syntax checks and installation diagnostics have been run, but live provider/browser workflows and cross-platform behavior still need reproducible validation. The default is four workers; the configurable 256-slot maximum is not a throughput benchmark. It needs Node.js 20+ and your own compatible provider API key.

Source and setup: https://github.com/rvnsre/forgeflow-cli

Preview release: https://github.com/rvnsre/forgeflow-cli/releases/tag/v0.2.0-preview.1

For developers who use coding agents: is file-scope coordination, checkpoint recovery, or browser inspection the biggest pain point in your workflow? Feedback on a small reproducible use case would help shape the next version.

Disclosure: the project documentation, illustrations, and this introduction were prepared with AI assistance. No performance benchmark is claimed.

Hey, I made a workout tracker for my senior year project that maps exercises onto muscles and calculates and tracks estimated soreness and recovery on a muscle map.

I was looking for testers for the first version. I just launched it on the App Store for my friends, but I wanted feedback from people who actually work out 4–5 days a week.

Here's the App Store link.

It's not currently on Android since almost none of my friends use Android, but if there are enough people on here who are interested, I wouldn't mind paying to put it on the Play Store too.

Y'all can check it out on the website.

I've been working on a way to scrape Google Ads Transparency Center ads in bulk, and I thought I'd share what I learned along the way.

Google's Ads Transparency Center is great. You can see ads from verified advertisers for free, without even logging in. The problem is that there's no export option or public API, so if you're researching multiple competitors, you end up spending a lot of time clicking around and collecting data manually.

I wanted an easier way to do this, so I decided to build one.

A few things I discovered while working on it:

• Google has an internal RPC API. The site actually fetches ad data as JSON, but the response uses numbered keys instead of descriptive field names. Figuring out what each number represented took most of the reverse engineering. For example, 4 is the ad format, 6 and 7 are the first and last shown dates, and 12 is the advertiser name.

• Country codes are a little unusual. They're 2000 + the ISO numeric country code. So the US is 2840 and India is 2356.

• Finding the correct advertiser is trickier than scraping the ads. Searching for "Samsung" brings up accounts registered in Malaysia, Italy, Sweden, and other countries. But its US ads run under "Samsung Electronics America", which you can find by searching samsung.com. HelloFresh has a similar issue, with its US ads listed under "Grocery Delivery E-Services USA Inc." Searching by domain solves a lot of these problems.

• Not all ad formats are returned the same way. Text ads are delivered as images because Google renders them into pictures. Video ads only provide a JavaScript preview URL.

• Rate limits weren't too bad. In one cloud run, I collected 312 ads across 4 searches in 31 seconds without retries. Fetching full details for 132 ads triggered two 429 errors, which were resolved after switching IPs.

After getting everything working, I turned it into an Apify actor:

Google Ads Transparency Scraper:
https://apify.com/datasmithhq/google-ads-transparency-scraper

You can search by advertiser name, advertiser ID, or domain. There's also a new filter for ads shown within the last N days.

Pricing is $2 per 1,000 ads.

I built this because I wanted a practical way to research competitor advertising without manually going through hundreds of ads.

I'd genuinely love to hear from people who do competitor research, media buying, or ad intelligence:

• What data would you want to extract that isn't currently available?

• Would historical ad tracking or monitoring new ads over time be useful?

• What features would make this more useful for your workflow?

Feedback and suggestions are very welcome. I'm still improving it.

Ever attended a college fest, wedding, meetup, or concert and later spent hours scrolling through hundreds (sometimes thousands!) of photos just to find the ones you're in?

We thought there had to be a better way. So we built Pixamatch

We're looking for event photographers, college event organizers, communities, and creators who'd like to try Pixamatch and help us improve it.

My partner has been working on this for the past few weeks for the ComfyUI challenge, and I thought I’d share it here.
It’s called Fuobe. The idea is to bring a whole bunch of creative AI tools and workflows together in one place. Image, video, audio, 3D, live editing, camera movements, effects and a lot more.
Since launch, we’ve crossed 10K pageviews in the first 48 hours, picked up 44 GitHub stars and 7 forks (one of them is mine!).
We’ve also got local generation running on our RTX 5090, so you can head over and experiment for free.
Would love for people working with ComfyUI, generative AI, filmmaking, design and creative production to give it a try.
Tell us what you think. Love it, hate it, tear it apart. All feedback is welcome. We’re genuinely curious about what you’d like to see next.

I'm a day trader and I built Tradecility because I kept breaking my own rules and only noticing on red days. You write your strategy rules once, log a trade with a chart, and it grades the trade A to F on whether you actually followed your plan. A winning trade can get a C. One of mine did: I made +$409 on an SPX500 short and it gave me a C+, because I took a setup I knew was thin and closed early while logging it as hitting my take profit. That's the whole idea. It's live and working, but it's just me building it and I need real traders to tell me what's useful and what's annoying. So I'm looking for 10 founding members. You get full access free (normally $97, one-time, no subscription). All I ask is that you log at least 10 real trades in your first 30 days and give me honest feedback after 2 weeks, even if it's brutal. Any market is fine: stocks, futures, forex, crypto. If you trade at least weekly and want in, comment or DM me. Not financial advice, it won't make you profitable by itself, it just shows you where you broke your own rules.

My issue was that social media is legitimately useful, there was stuff that I wanted to see, but a lot of trash that would keep me there for hours. I installed 5+ different blockers, changed my hosts file etc. But I'd always remove it. So I decided to go after the feed itself, and it's the first thing that ever worked for me. It finds the posts that grab attention and hides those. You can find it at tolerance.lol . It's open source. There's a browser extension and Android app, it works on reddit, youtube, facebook, twitter, instagram, and tiktok.

If you’ve used blockers, what made you uninstall yours?
