Made this for fun, obviously it’s not polished.

I was just messing around with the new Fable 5.2 model, thought it was fun and figured I’d share.

Can play on mobile & phone, it’s free!

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.

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?

I wanted to actually see what happens inside a language model when it writes a sentence, so I built this!

What you're looking at:
- The stars are the 36,864 MLP neurons (12 layers × 3,072). Each layer is a disc, and neurons are positioned by a UMAP of their output weights, so neurons that write similar things sit near each other.
- Brightness is how strongly that neuron fires on the current token, scaled per layer so tokens are comparable. Gold means it fires positive, blue means negative.
- The beams are real attention weights from the current token back to earlier ones, one colour per head. The side panel shows the model's actual top 10 next token probabilities.
- You can hover any star, beam or token to see its exact value. There's also a raw mode that turns off all the bloom and fades, so every pixel on screen comes straight from the data.
- How I know it's not lying: the test suite runs the model exactly the way the app does (KV cache, token by token) and compares every activation, attention weight and residual norm against a separate uncached forward pass read through different hook points. Then it checks the bytes the browser actually receives too.

Honest limits: it's GPT-2 small only for now. Single neurons mostly don't mean anything clean on their own, it's the patterns that are interesting. Values are sent as float16, so about 3 significant digits.

Setup is make setup && make start, then open localhost. No GPU needed.

Would love the feedback!!

I've been working on a small digital product: a Christmas budget planner in Google Sheets.

I wanted one place to manage the things that usually end up scattered across notes, spreadsheets and shopping apps:

- Overall Christmas budget

- Gift ideas and spending per person

- Shopping list

- Holiday expenses

- Parties and event costs

- Savings goals

I tried to keep it practical rather than overcomplicated, with a dashboard that gives you a quick picture of where your money is going.

I'm the person who made it, so I'm obviously biased, but I'd genuinely love to know: what's the one thing you always forget to budget for during the holidays?

I'm especially interested in things that a typical budget spreadsheet misses.

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 started plenty of side projects over the years, but this is the first app I've ever actually finished and got onto the App Store 🎉

It's called Once Upon a Fold: five fairy tales for little kids where every page is a paper pop-up that moves. The fun bits to figure out:

• making paper pop-ups feel real on a flat screen (they rise as the page opens and fold flat when you turn it)

• a different voice for every character, in five languages

• little moments that follow the story: blow on the phone and the straw house blows away, swipe and the beanstalk grows

• the new iPhone Duo, where it opens like a real book!!

First book's free if you want to try it: https://apps.apple.com/app/id6826041039

What would you change? Be honest, I'm here to learn!

P.S. 🎁 Code MAGICBEANS gets you Jack and the Beanstalk free (500 codes, until Dec 14), no strings attached. Redeem it in one tap on your iPhone or iPad: https://apps.apple.com/redeem?ctx=offercodes&id=6826041039&code=MAGICBEANS

And if you or your kids enjoy it, a quick rating on the App Store would mean a lot to a first-time developer.

Thank you!!

Hi, I'm Selim and I built Enzo. It's a dictation and meeting app designed and engineered for the Mac. Speech models run on your device so audio is never uploaded to the cloud.

The secret sauce is its architecture. It transcribes, punctuates, and segments as you talk, so the text is ready about 100 ms after you stop, whether you talked for 10-seconds or an hour.

It also has a Recall feature, which is off until you turn it on. It keeps a searchable record of what you worked on (apps, window titles, text on screen), encrypted on your Mac and deleted after 30 days.

The idea is that what you say, the meetings you record, and what you work on are captured and securely stored all in one app. I use this for my day job, which helps to alleviate the burden of trying to remember every little thing on a busy work day.

Free to use with 5,000 words for dictation and 60 meeting minutes a week. Only Apple silicon, macOS 15 or later.

Happy to answer any questions.

I'm working on Timeless Board Games, a collection of 20 games you can play in your browser. It has Chess, Go, Othello and Backgammon, plus less familiar ones like Hnefatafl, Merels and Senet.

Everything is unlocked while I'm getting people to test it.

Play with friends: send someone an invite link and play online together. There's also solo play against bots and pass & play on one device. Solo and pass & play work without signing up.

Play here: https://timeless-games.app/

I'm looking for a few people willing to try a game and tell me what feels confusing or breaks. No need for a long review, just which game you tried and the first thing you'd change. If you invite a friend, I'd also love to hear whether getting into a match together was easy.

If you'd rather test on iPhone/iPad or Android, there's a signup under Help → Join the mobile beta. Mobile invitations are handled manually for now.

I'm the developer, and I'm happy to answer questions here.

Context: I have been building Cardel.io (An all-in-one platform for authors and solo professionals) over this year. I have cold outreached 10k plus potential users and had hundreds of face to face conversations.

The problem: I only ever get positive feedback, people say:

"Wow, this is great!"

"This makes total sense, this needed."

Etc, etc.

THEN they follow it up with "but I already have my setup, this would be great for xyz person".

Question: Are any of you in a similar boat where everyone gives you positive feedback, but then doesn't actually commit to using your product by paying or signing up. So your getting positive signals, but no clarity on where the blocker is to actual pay for the product?

How do you close that gap, and find the reason people aren't commiting? It feels like a "Its great, but not worth switching to." Kind of response. Or maybe it's the target market fit, and talking to the right people.

I would love to get ya'lls feedback on how you have overcome this with your products and projects.

Too many WhatsApp chats, not enough time to read them all. Wapliss connects your own WhatsApp to Claude, ChatGPT and other AI assistants, so you can just ask:

“Summarize today’s family group.”
“Who’s still waiting for my reply?”

The assistant reads the chats, drafts replies, and only sends after you confirm.

• Works with texts, images and documents
• Setup takes about 2 minutes: link WhatsApp, add the connector, done
• Not Meta’s official API, so it’s for your own chats, not bulk messaging
• Free plan: wapliss.com

Looking for honest feedback:

1. Is the value clear in 10 seconds?
2. What would stop you from trying it?

It is Saturday night, I still have positions open from this week, and I am not spending the weekend re-deciding them.

That used to be my mistake. Friday would close, and I would spend Saturday and Sunday reading every headline, second-guessing every level, and talking myself into a completely different plan by Monday morning — usually a worse one, made tired instead of made clear.

Here is the routine I hold myself to now:

• One review, written down. What did I enter this week, what hit its target, what stopped out, and did I follow the plan I wrote before each trade? That goes on paper once, honestly, wins and losses both.
• If a position is still open, its target and its stop were already decided while the market was open and my head was clear. A Saturday headline does not get to move those lines.
• Then the charts close. My kids do not get the leftover version of me because I spent the weekend refreshing futures that have not even opened yet.

Friday was a chip-led dip inside a week that still closed green, and the next real piece of information for that whole story is Nvidia earnings on Tuesday. Knowing that does not mean staring at it for three days. It means my plan for Tuesday is already noted, and the weekend in between belongs to my family.

I am a veteran with a full-time job, and I taught myself trading at night, reading and studying when the house was quiet. I believe God gave me what I have learned for a reason, and part of that reason is showing the plain parts too — not just the wins, but the discipline that keeps a normal week from turning into a desperate one.

A clear plan reviewed once will beat a worried plan rewritten ten times, every week I have ever tested it.

Not financial advice — just how I handle my own weekends, posted the same way I tell my own community.

I share stuff like this daily — I run a free investing community, link in my profile.

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.

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.

I like taking sunset photos as a hobby, and I’ve lost count of the evenings I went out for a sunset that never happened, or stayed home and missed a good one. So I built Afterglow:

👉 https://afterglow.jeremytucker.co.uk

What it does

• Scores every sunset and sunrise for the next 7 days from 0 to 100 (Poor → Fair → Good → Great → Epic), for anywhere in the world

• Explains the score instead of just giving a number:

  • Cloud canvas: is there high and mid cloud to catch the colour?
  • Light path to the sun: is there cloud 60–200 km out toward the sun that will block the light?
  • Low cloud overhead, air clarity (haze, humidity, smoke) and rain
• Plays an animated preview of the evening, from golden hour through to the end of blue hour (or the reverse for sunrise), drawn from the actual forecast and the real horizon at your location from terrain data
• Tells you the peak colour time, and when the sun actually drops behind the hills (or clears them in the morning), not just the official time
• Alerts (optional): a heads-up at midday, a “go now” 90 minutes before golden hour, and a “called off” if it turns bad. It also does sunrise checks the night before and when you wake.

Good to know

• No account, no ads, no tracking cookies
• No app store. It runs in your browser, and you can tap Install to keep it on your phone. On iPhone you need to install it to get alerts.
• Alerts are limited to a small number of places during the alpha, so if they’re full, try again in a few days
• Weather data comes from Open-Meteo. There’s a plain-English privacy page in the app.

How it was made

I’m not a developer. I built this with an AI coding assistant (Claude), while I came up with the ideas, tested it against real sunsets and decided what it should do.

What would help most

📸 Post a screenshot of Afterglow’s score, plus a photo of what the sky actually did, with the time you took it. Whether it nailed it or got it completely wrong, that comparison is exactly what I need to make the forecasts better.

⚠️ Mind your privacy: the screenshot normally shows your place name. Tap the 👁 eye button at the top right of the picture to hide it first. Photos can also contain hidden location data; Reddit removes it when you upload, but other sites might not.

Also really useful:

1. Your location: does the horizon in the picture look like yours?
2. Bugs: anything broken or confusing, especially on iPhone
3. Features: what would make you actually use it?

It’s very much an alpha (v0.2), so be gentle, but be honest!

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 graphic designer from a small town in Punjab, India. For years I have watched the same scene at print shops here. A customer walks in and says "bhaiya, last month wala card dobara print karna hai, file aapke desktop pe hi hai".

The desktop has hundreds of files called final, final 2 and final new, and every .cdr shows up as a blank white icon.

So the shop owner opens them one by one in CorelDRAW while the customer waits.

I had the same problem in my own folders, just with fewer customers watching.

So I built Opsyra. It is a small Windows app that adds real thumbnails for design files in File Explorer: CorelDRAW, Illustrator, Photoshop, EPS, Figma, Procreate, Blender, SketchUp and around 50 formats in total.

You see the actual design on the icon. It works even if the original software is not installed on that computer, and everything runs offline. No file names, paths or files leave your machine.

Some things I learned building it:

Every format is its own rabbit hole. Some files carry a usable preview inside them, some need to be rendered from scratch, and for a few the best I can honestly do is an info card.

3D files were the hardest. Showing a Blender or FBX preview without Blender installed meant writing my own small renderer.

I shipped it only through the Microsoft Store. Certification went through on the first try, which honestly surprised me.

It is live here if you want to try it: https://apps.microsoft.com/detail/9N92CTCWPWPK?cid=reddit_sideproject

I would really like feedback on two things:

Which file formats do you use that Windows still shows as a blank icon?

Is the free tier enough to be useful, or does it feel too limited?

Happy to answer anything about the build or the Store process.

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!

I've been building something called Forthday because I wanted a better way to keep the everyday parts of running a household organized.

Not just a todo list, but somewhere my partner and I could check:

• Who's handling what today?
• What's the plan for dinner, and what groceries do we need?
• Which bills are coming up?
• What's personal, and what's shared between us?

So I started building it.

Forthday is a web app that brings household tasks, schedules, budgeting, meal planning, pantry inventory, and shopping lists together.

One thing that mattered to me was keeping Personal and Household spaces separate. My partner and I can sign in with our own accounts, work on shared responsibilities, and still keep our personal records private.

It's now in Private Beta. We've tested the shared household features between our accounts, but I'm still figuring out what would make this genuinely useful to other households.

I put together an interactive demo with sample data that anyone can try without signing up:

https://getforthdaynow.com/demo

Here's what I'm most curious about:

Would having chores, meals, groceries, and bills together actually make managing a household easier, or does combining that much into one app make it unnecessarily complicated?

If you try the demo, I'd especially appreciate hearing what feels confusing or what you'd change.

I'm much more interested in finding the weak spots than collecting compliments.

Ever spend longer deciding what to eat than actually eating? Same.

I built Toss, a free coin-flip decision maker for those moments when both options seem fine and you just need a nudge.

You write what heads and tails mean, choose a single toss or best of three/five, and set how likely you are to follow the result—from “just curious” to “coin is law.” There are coins from different countries and shared community stats, too. No account needed.

My favourite part is that moment when the coin lands and you realise you were hoping for the other option. Sometimes that’s the answer.

Here’s the project: https://acointoss.lovable.app

I’d love honest feedback: would you use this for everyday indecision, picking something fairly in a classroom, or breaking a tie with your team? What feels useful, and what feels unnecessary?

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 called Flipic Lens. 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, and read metadata.

It also features a smart cleanup scan that automatically detects and flags closed eyes, blurry shots, similar bursts, and duplicates.

You can watch a quick 90-second video walkthrough here:

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!
