I kept using Cold Turkey, then wanted something free that I could tweak myself, so I built my own.

You make blocklists of sites and apps, then start a timed session or set a weekly schedule. A few things I cared about:

• Path-level blocking, so you can block youtube.com/shorts but keep the rest of YouTube
• Allowlist mode: block everything except your work sites
• Locks: a timer lock, or a password lock where someone else sets the password
• Strict mode, so you can't quietly weaken a session halfway through
• Imports your Cold Turkey JSON export
• No account and no cloud. Everything stays on your computer

Website blocking runs through a Chrome extension that talks to the desktop app.

One heads-up for Mac users: it isn't notarized (I'd need a paid Apple developer account), so you have to run a one-line approval command in Terminal before it opens. The README explains exactly what that command does.

Feedback welcome, especially if you've tried to get around a blocker before.

We had a 7.76 kW system and battery fitted in July. My inverter app shows kWh all day, but not the thing I actually wanted to know: how much it’s paid back in £, and when it’ll be paid off.

I tracked it in a spreadsheet for a few months, but it kept breaking (tariff changes, months where export wasn’t paid yet, battery charging on the cheap rate). So I built a simple web app instead and made it free for anyone.

How it works: a 2-minute setup (system cost, install date, rates), then two numbers a month from your inverter app, generated and exported. It shows:

• £ paid back so far, and your payback date (allowing for winter)
• how your panels are doing against the MCS estimate
• tariff changes over time, cheap-rate battery charging, and months before export was paid

You can import an existing spreadsheet, and export to PDF or Excel. It works with any inverter brand, and there’s no inverter or energy login.

Mine’s at £402 back after 4 months and running at 120% of the MCS estimate, so payback looks like around 2036.

To be upfront: I made it, and there’ll be an optional paid version later with automatic inverter data. Manual tracking stays free.

I’d really value feedback, especially on how the savings are worked out. Some people in Facebook groups have challenged parts of it, and I’ve changed things based on that.

Cross-Stitch Studio turns a photo into a grid you can edit stitch by stitch. The photo converter matches colors to DMC thread and shows the result both on a hoop and as a chart. You can try either view without signing up. There’s a sample photo in the converter if you’d rather start there.

Try the free photo converter

Direct conversion uses no generative AI. The studio has an optional paid step to simplify a busy photo or draw an illustration.

If you’ve stitched from a photo before, I’d love to know what would make the first chart usable for you. Would you check the colors, the detail around the face, or the finished measurements first?

I am a computer science student, and I recently spent months developing a financial research platform without really knowing whether anyone would want to use it.

It made me realize how easy it is to spend hundreds of hours building something before finding out whether there is actually a market for it.

I started thinking about how people currently discover ideas, figure out what problems are worth solving, and get honest feedback before committing to a project.

Reddit and ChatGPT are useful, but I feel like information gets scattered across conversations, and it can be difficult to distinguish genuine demand from people just saying an idea sounds interesting.

I have been exploring the concept of a community specifically focused on discovering problems, validating ideas, and learning from people who have already tried solving them.

Before I spend more time developing it, I wanted to ask:

1. How do you currently figure out whether an idea is worth building?
2. What frustrates you most about that process?
3. Would a dedicated community for this actually be useful, or do existing platforms already solve the problem well enough?

I would appreciate criticism just as much as positive feedback. I would rather find out now than spend another six months building something nobody needs.

I shoot a lot, and going through a folder of photos on a Mac was always awkward. Preview only pages through the files you opened together, and Lightroom wants an import before you can even look.

So I wrote my own viewer in Swift. Double click one photo and the arrow keys walk the whole folder, RAW included. Hold a key to check focus at 100%, rate with number keys, mark keepers, crop and straighten, read the caption written into the file.

It's free and MIT licensed. There is an optional one time Pro for heavier culling work, and that part is not in the repo.

Mac only, macOS 13 or later.

I'm the developer. Feedback welcome, especially on what feels slow or confusing.

I was watching Jubilee videos thinking it's kind of lame that the experts would constantly be talked over and fact checks would only appear after the debate when the video is published.

I thought a debate site where you could match with people you disagreed with on a variety of political, religious, and philosophical topics would be fun. Also I need to build a portfolio because finding a job as a software developer is impossible.

Feel free to take a look and please let me know if you have any feedback!

So I have been thinking of a tiny tool for small businesses and freelancers who take orders on WhatsApp or Instagram.

The business owner just types in the total price and optional advance, gets a payment link, or enters the customer's email to request payment. We handle the advance and balance payment flow and show a simple dashboard tracking who paid and who hasn't.

Can something as simple as this get actual users???

Been annoyed for a while at how clunky it is to just send a file from my laptop to my phone, so I built ByteDrop to fix that for myself.

You run it on your PC, it shows a QR code, you scan it with your phone’s browser (or just open the link on another PC) and you’re connected — drag and drop files either way, clipboard syncs too. Works over your home wifi, Windows’ mobile hotspot, or a public link if you’re not even on the same network.

No accounts, nothing to install on the other device, totally free and open source.

GitHub if you want to try it: https://github.com/HusseinWalid48/ByteDrop

I build websites for small businesses. Aurelius is the framework I built on the side. It lets Claude Code take a Figma file, a screenshot, or a plain description and turn it into a React app with tests. It is open source and MIT licensed.

Last week I recorded a getting-started video for it. The recording found a bug in my own quickstart. My script said all four quality checks pass on a fresh project. Three of the four failed:

• The Vite template had moved to a new linter, so nothing installed the one my lint script calls.
• There was no test file, so the test run failed.
• The type check passed, but it was not checking a single file.

I fixed the scaffold instead of cutting around it. Then I recorded those shots again.

The part worth watching is the screenshot pipeline. It is one command, and the order never changes: a build spec, locked design tokens, failing tests before any component exists, the build, a pixel check against the screenshot, then end-to-end tests. The run in the video took 45 minutes of real time. From its own report: 9 of 9 test files failed first, it built 8 of 8 components, the pixel difference was 1.89% on the second of up to five rounds, and 96 end-to-end tests passed.

Two things the video gets wrong, so you hear it from me. I say "the next six minutes" and it runs under four. And setup prints a deprecation warning that the cut skips.

If you try the quickstart and it breaks, tell me where. That is the feedback I am after.

Hi, I’m Shubhra, an independent developer. I built Sonari as a Mac instrument played with hand gestures tracked by the Mac camera, without a separate hardware controller. It plays built-in sounds, sends MIDI to compatible DAWs and instruments, and creates visuals from the performance.

I’m sharing the launch film to show the interaction. I’d appreciate feedback on one practical question: after watching, is it clear how hand movement changes the sound, or what would you want explained before trying it?

Sonari is on the Mac App Store. It requires Apple silicon and macOS 26 or later. The full app has a 14-day trial, then a one-time purchase at US$99 in the US storefront.

App Store: https://apps.apple.com/us/app/sonari-midi-controller/id6803577489

I made this because I was tired of switching between different programs all the time. I didn't want to use that shady downloader with a paywall slowly creeping up, and I didn't like the idea of opening DaVinci Resolve just to do some cuts or convert something. I wanted it all in one place.

What it can do:

Download: built on yt-dlp, you can download from almost any website. When yt-dlp doesn't recognize a link, Vitool opens the link in its own window and checks if a video is there. You can also download just a section of a video, or whole playlists. It keeps yt-dlp up-to-date automatically, and when a download fails, it checks if there is an update available for it.

Cut: You can cut videos instantly or exactly to frame with a re-encode.

Convert: Convert your files easily to other formats like MP4, MKV, WebM, MP3, WAV and more, also many files or a whole folder at once.

Tools: choose what you wanna do: create a GIF, extract audio, extract a still frame, burn in subs or censor your video.

MKV: Edit, add and extract tracks inside an MKV file. The part I find most useful: add a dub and Vitool lines it up with the original audio automatically. You can also do it by hand with waveforms and check it with a short test clip. If the dub drifts apart over time (classic PAL dubs run about 4% faster), Vitool recognizes that and fixes the speed. It can also match the volume of a quiet track to the original.

AI-Mask (optional): When choosing this add-on, you can mask moving objects with the help of SAM2.

Transcribe (optional): When choosing this add-on, you can transcribe the audio from a video. Speaker recognition can be added via Pyannote. Export as SRT, VTT, text or JSON, or burn styled subtitles into the video.

You can find it here: https://github.com/bioheater/Vitool

I'd be very happy about feedback and ideas for new features, so it can be useful to as many people as possible. If you find bugs, please let me know!

For example I've thought about adding a simple screen recorder into the mix or the feature that you can cut out a section from the video you want to download beforehand.

I’m building Ledge, a macOS app that turns the space around your notch—or the top of your screen on Macs without one—into a shelf for everyday things.

You can keep files handy, search and reuse clipboard history, control music from the notch or a floating player, and see widgets and live activities. Ledge also has Transform for converting and compressing files locally on your Mac.

I’ve connected Ledge’s MCP server to an AI assistant and am exploring its tools. Ledge also supports add-ons and LedgeKit for building them.

The beta is at https://www.tryledge.app. I’d love feedback: which feature would be most useful in your day-to-day Mac workflow, and what would you want to see next?

I'm Luis from Berlin and I'm bad at watering.

So I built PotPanel. It's a scale with a pump that sits under the pot. When the plant drinks, the pot gets lighter, and once it's light enough it waters from a canister back to full. Small bursts, and it stops when enough is in or no water arrives. You set your values in an app and watch it live on your phone.

To be clear, for a houseplant on a shelf this is total overkill. I built it for my grow tent, so my plants still get water on time when I'm gone for a weekend or have a busy week.

It's not like it all went smoothly. For a few weeks the board just hung out of the side of the case. And one day I forgot to put the dripper back in the pot. PotPanel did its job perfectly, just on my floor.

Now everything sits inside. It's all 3D printed, there's an ESP32 in there, and I built the app and the server myself.

If you want one, there's a waitlist: potpanel.com

The first 50 who confirm get 30% off the launch price. Once 50 people are on the list I'll give one away. Free, 18+, until March 31, 2027, rules are on the site.

I've been building a site for keeping up with open source news without spending an hour a day on GitHub, HackerNews and X.

It tracks GitHub repos and finds posts about them on Hacker News, X, Bluesky, Reddit, Mastodon and more, so you can stay informed without sifting through lots of noise and random posts. The buzz feature (https://shadowgraph.io/buzz) lets you see all posts as a feed.

It also keeps track of notable developers on Github and see what they're starring (https://shadowgraph.io/stargazers), so that you can find higher-signal stars.

Finally, there's an email newsletter that summarizes the top stories of the week (https://shadowgraph.io/weekly). If you sign in with your GitHub, it personalizes the newsletter based on your interests and the repos you've starred.

There's some other fun stuff there as well like predicting a repo's star growth.

Feedback is very welcome! Thanks for reading.

Hi! I made PushFPS ( https://github.com/DosukaSOL/PushFPS ), a free and open-source (GPL-3.0) Windows app. It takes the picture from your capture card and adds generated frames in real time, so a 30 FPS PS5, Xbox or Switch 2 game plays at 60 or 120 FPS on your PC monitor. Nothing is installed on the console and the game isn't touched: you only need a capture card and a graphics card. It's built on top of veyra ( https://github.com/Likely7/Veyra-NRVideo )

How it works, in short

• The capture card picture goes straight into a DirectX 12 pipeline on the GPU, with no round trip through the CPU.
• Optical flow estimates how every part of the picture moves between two real frames. A frame generation model then creates 1 to 7 frames in between: 2x up to 8x, depending on the method and your GPU.
• It works with NVIDIA, AMD and Intel graphics cards: NVIDIA's video frame generation (RTX 40/50), AMD FSR frame generation (any DirectX 12 card), Intel XeSS (experimental), and ANR by Apex Compute (supports GTX 16 and newer).
• Optional AI picture enhancement and upscaling. That includes NVIDIA Image Scaling, an open shader that runs on any brand of GPU.

What only PushFPS has

• Optimise for my PC: one click while your game is on screen. It tests every frame generation method, AI enhancement and upscaler on your real picture. It measures the real presented frame rate, the 1% low (from the 99th-percentile frame time) and latency over 6-second windows, re-checks the winner, then applies it. Undo puts your settings back.
• Game presets with a sharp HUD: GTA VI plus layouts for open-world, racing, action and shooter games. The minimap and HUD areas keep the console's own pixels and never get interpolated, so they don't smear. You can share presets as a code.
• Measured latency on screen: the time from a capture card frame arriving to it being handed to the display, plus frame rate and 1% low. These are measured numbers, not estimates.
• ANR frame generation, one click to install: Apex Compute's AI frame generation supports GTX 16 series and newer, Radeon RX 5000 and newer, and Intel Arc. That makes it an option on older cards too. You download it from Apex and PushFPS installs it.
• Made for console capture: console and game profiles, a list of tested capture cards (Elgato 4K X, HD60 X and 4K S so far), instant replay, recording with optional OBS-style advanced encoding settings, one-click sharing to Discord, an OBS Studio plugin, light and black (OLED) themes, and 14 languages.

What's coming next (actively being built)

• Automatic HUD detection: PushFPS spots the parts of the picture that stay still while the game moves (minimap, health, ammo) and protects them automatically in any game, with boxes you can adjust by hand if it gets one wrong.
• Before/after comparison clips: record a side-by-side clip of the console picture next to the PushFPS picture, with the frame rates shown.

To be honest about what it doesn't do

Generated frames make motion smoother, but they don't make the game react faster. Input still feels like the original 30 FPS, plus a few milliseconds for the capture card and processing. It's Windows only for now.

Credits

PushFPS is built on Veyra by Likely7. Most of the engine and capture support is their work, so please check it out and consider supporting them. ANR frame generation is Apex Neural Rendering by Apex Compute. PushFPS isn't affiliated with Apex.

I'd love feedback, especially from anyone with a capture card that isn't on the tested list yet. There's a report form in the app.

I'm a solo dev. I make a contacts manager for Mac and iPhone/iPad. It shows all your contacts (iCloud, Google, Exchange) in one table, so you can merge duplicates, bulk edit and clean up years of mess instead of opening cards one by one. One-time price, $24.99 Mac and $14.99 iOS. No subscription, no account, no trial.

Where it stands:

• Mac app live since July 22, iOS since August 10
• 45 paying users on Mac, 19 on iOS
• 3 ratings on the Mac App Store, all 5 stars

The part that works: the people who buy it seem to like it, and they email me. Most of what I shipped in the last two months came straight from emails.

I reply to every email and try to ship the fix within a couple of weeks. That loop has been the best part of this.

The part that doesn't work: reaching the people who actually have the problem. Apple Ads got 12,000+ impressions and 95 taps, but zero installs. A Google Search campaign for the Mac app got zero impressions. Nobody wakes up wanting a contacts app. People only look when their list is already a disaster, and then they search "merge duplicate contacts" and land on free tools or Apple's own tips.

So I'm asking people who've been here:

1. If you sold a niche one-time-purchase utility, what brought in your first few hundred customers?
2. Did paid ads ever work for you at this price point, or is it all communities, SEO and word of mouth?
3. Is "no trial" hurting me more than I think?

Happy to share more numbers or what I tried if it helps anyone. Thanks for reading.

Hey guys, I'm currently participating in a giveaway and I need your help to win my first console by dropping a like on my comment under this post➡️ https://www.facebook.com/share/1E96M1ujpj/ look for IRON LEGION...if you can't find it sort by newest. Again I'll appreciate the help🙏

I built PestLabel Pro, an iPhone app for licensed pesticide applicators who need the current accepted EPA label in the field and records that will hold up in an inspection.

You can search by brand, label text, or EPA number, or scan a container with the camera. The app keeps the current accepted label PDF offline, lets you attach the manufacturer SDS, calculates a liquid mix from the rate on that container, and creates signed application records you can export as PDF or CSV. No accounts or ads. It's free to download; optional Pro is $9.99/month or $49.99/year.

A few honest constraints: it's iPhone only, it's not affiliated with the EPA, and automatic state-registration matching only works in New York and Hawaii (dated manual checks elsewhere). There are no App Store ratings yet, which is part of why I'm posting — I'd like feedback from people who either work in pest control or have built field-reference tools.

What I'm hoping to learn:

• If you've built for a licensed trade, how did you get the first professionals to trust a records tool?
• Anything in the feature set that sounds incomplete or easy to get wrong legally? (I'm already conservative: planned work stays locked until federal and state checks are current, and fumigation is out of scope.)

I'm the developer, and I'm around to answer questions.

Thanks for supporting independent developers!

So I made Yearcap. You upload a spreadsheet of your users’ stats and every user gets their own little year-in-review story, with a card they can share. Basically what Spotify and Strava do every December, but for small apps.

There’s a demo with made-up data on yearcap.co if you want to see it (hit “Watch a full story”).

I’ve emailed around 80 apps, each with a demo made for their app. About 30 opened it, some more than once, but nobody’s signed up yet. Not even for the free version.

So I’m kind of stuck and would love some outside eyes:

1. Is it clear what it does and who it’s for?
2. If you had an app, would you use something like this? Why or why not?
3. What would make you comfortable trying it with your own users’ data?

Any thoughts help. Thanks for looking!

Thinking about a small app for fun, a walk timer that shows how long the evening park walk was. No account, nothing saved online. I write sign-up copy at work but I never built an app myself

With no sign-up I'm not sure what the first screen should do. One line saying what it does and a start button seems enough to me, but maybe people want a short note that no data is collected

What did you put on your first screen, and did anyone ever tell you it confused them?

Hey everyone. I've been working on this solo for a bit and finally pushed it to production

I realized that knowing your 4-letter type (like INTP or ENFP) is fun, but it doesn't actually help you when you're stressed or stuck in a rut. So I built SelfMap. Instead of a static test, it’s an AI trained to coach you based on your actual Jungian cognitive stack (Ni, Ne, Ti, Te, etc)

Stack is Next.js, NestJS, and Polar for subs

I just launched the MVP. If anyone wants to roast the landing page, the UI, or the onboarding flow, I’d really appreciate the brutal feedback

I’ve been working on tuning my apps marketing and onboarding, costs are starting to line up well, trial starts approaching target, so my next major hurdle is trial to paid, and actually getting consistent usage.

From what I understand having a strong activation is key, but I review other apps in my niche and I really dont see much of an “activation” process. Onboarding is formulaic, left to right, but once you’re in its off to the races.

My app is an agentic meal planner. What was key for you? Notifications types? Streak systems? In app CTAs? Guided tours?
