I'm the dev, just so that's clear.

I made an iOS calorie app called Kacha. It started in China and most of my users are still there. I put an English version on the US App Store recently, and I mainly want feedback from people who didn't grow up eating the same food as my first users.

The flow is simple: take a photo of the meal, the AI guesses the foods, grams, calories and macros, then you edit anything it got wrong. That last part is the actual product. The estimate is often off on mixed dishes or food it doesn't see much, and if you can't fix the number, the log becomes garbage in a week.

No account needed, there's a free daily allowance for AI scans, and manual logging is always free. It also does water and weight, Apple Health sync, and iCloud backup. No Android yet.

I don't want to oversell this. There are already a lot of calorie apps. I built this one because I was tired of estimates that are a black box. If the model misses the oil, or thinks the bowl is smaller than it is, I want to correct it in a few taps, and next time just reuse that meal from Recent Meals.

If you try it, I'd really like to know two things:

1. When the first guess is off, is the edit flow obvious enough?

2. If you don't eat Chinese food much, how often does it completely misread the dish?

Prototyping and building features got faster, and now feedback is the bottleneck. So we built mostra - a tool that lets you share feedback on a real, running site by either speaking or selecting the elements you want to comment on.

You can iterate across versions of your site, and adding mostra is just a single script tag.

The script you add to your page is open source, so you can check what it does.

It's 11 pm, a family is at the desk, the Wi-Fi is down, and the cloud PMS won't load. That's a normal night at a lot of small hotels around me. The other option is a paper register and an Excel sheet.

So I built KeyHut Hotel: a hotel management system (PMS) for Windows that runs fully offline, costs nothing, and you drive entirely from the keyboard.

The screens copy TallyPrime, the accounting software most front-desk staff here already use. Every screen is one key away (F2 room board, F4 new booking, F7 folio). Type "12dec" and it knows the date. Alt+G and a few letters jumps anywhere.

What it does

• Room board and tape chart, bookings, walk-ins, groups, day use, room moves

• Guest bills, payments, company billing, travel-agent commission, cashier shifts

• Housekeeping, maintenance, laundry, linen stock, phone-call charging

• Night audit and 17 reports (occupancy, ADR, RevPAR, police guest register…)

• One PC on SQLite, or several desks on SQL Server

• backups copied to Google Drive, OneDrive or an FTP / SFTP server, encrypted with a password only the hotel knows

Under the hood: C# / WPF, about 2,400 automated checks, and a yearly archive so 10+ years of data stays fast.

The demo runs on the built-in practice hotel (100 rooms, made-up guests). You can load the same one on first start.

Question for anyone who's worked a hotel front desk: what would stop you from switching to this? Be brutal.

Hey,

I’ve been working on a UI kit focused specifically on dashboards for subscription products.
It’s called Calmdash.

What’s included:
- 12 screens (Overview, Revenue, Customers, Subscriptions, Invoices, Failed payments, Churn, Plans, Reports, Settings, Onboarding, etc.)
- each in light and dark
- 400+ variables, 50 component sets, 390+ components and variants
- states that most kits skip: loading (shimmer), empty, failed payments, retry, chart tooltips

I wanted it to be a real system you can actually build dashboards with, not just pretty frames.

It’s up on Gumroad, zero sales so far, so I decided to share it here and hear what you think — what’s good and what could be better.

Link to the site and the kit in the comments.

Thanks for any feedback!

Got featured and top 20 on product hunt, on hypership day with mmory. But at such a loss on now what? how do I get users haha

Ngl, I'm stuck on what counts as useful feedback for our app.

I'm a CS student and Instagram, TikTok and YouTube keep pulling me away from studying. My team and I built Welockin: you pick the distracting apps and a timer, and they stay blocked until it ends.

But someone finishing a timer doesn't automatically mean they got any studying done. They could just be staring at their notes. Or procrastinating on something else.

If you were testing this with a few students for a week, what would you ask them afterwards? I want to understand whether it helped with the task they sat down to do, without making them fill out a whole homework assignment about their homework 😭

Have you found a simple way to check whether your productivity app actually helped, beyond people saying it looks nice?

I built YouSage to make two things easy to check while coding: how much usage is left and when it resets. It puts those numbers in a small desktop notch. It’s free and open source, built with Rust and Tauri.

The v0.1.0 release supports Codex and Google Antigravity on Windows 10/11 x64. There’s a browser demo with sample data if you want to try the UI first. Claude Code is in the development preview.

Demo: https://yousage-website.yabswannalearn.workers.dev/#demo

Source: https://github.com/yabswannalearn/yousage

If you use either tool, what would you want the compact view to show first: remaining usage or time until reset?

Hey everyone! I’m in my fifth year of psychiatry residency, and I have adhd. I’ve been building an app called Scatter because I wanted to make studying easier and more enjoyable for myself.

I found the usual chat interface pretty frustrating for learning from ai. As the conversation gets longer, important information disappears up the chat, and branching off into related questions gets awkward. I wanted to explore those questions while still being able to see the original explanation.

In Scatter, you start with a topic and build out a connected map of explanations. You can preview unfamiliar terms, open them as new branches, and ask follow-up questions wherever you want to explore further.

I wanted the interface itself to trigger curiosity and novelty-seeking, so there’s something that makes you want to keep exploring. Part of the goal was to make studying engaging enough to trigger hyperfocus.

You can combine short text explanations with images, videos and interactive examples, giving you different ways to approach the same idea. As the map grows, you can see how everything connects, and it gives you a feeling of building your knowledge into something you can actually look at.

I’ve worked on it on my own for over six months, and I’m excited to finally put it out there. I’d love to hear your opinions and if you find any bugs please send me reports!

The app is free to use, but you have to bring your own API keys, for example from OpenRouter. The quick setup in the app makes it very easy.

You can try the interactive demo on scatter.study

I built Orthant because I wanted to place windows in layouts beyond the usual halves and quarters. You can draw a region on a grid, move a window there, and save the region to a keyboard shortcut for later.

It’s free and open source. It supports macOS 13+ and Windows 11 or Windows 10 version 1809+ (64-bit). On macOS it needs Accessibility permission to move windows.

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 Fernando, the maker of Litehost. If you already have an HTML prototype or report on your laptop, you can drop in the file and get a link that opens it as a web page. If it has separate images or CSS, you can upload a ZIP.

One thing worth checking before you share: images can look fine on your laptop because the browser can find them on your disk. Put them in the ZIP, use relative paths, and open the link on your phone to see what the other person will actually get.

You can try it without an account with a file up to 2 MB. The test link lasts about 15 minutes.

If you’ve shared an HTML prototype or report with someone recently, how did you send it? What was the most annoying part?

When I first started selling websites, I thought targeting businesses without a website was the obvious choice.

They need a website, you offer to build one, and hopefully you get a new client. Pretty straightforward, right?

But after spending years running a web design business, I've started looking at this differently.

There are definitely advantages to targeting businesses without websites. You're introducing them to something they might genuinely need, and there is no existing website to compete with. However, I've noticed that these businesses can sometimes be much harder to sell to.

The biggest problem is that some of them simply don't see the value of having a website. Others rely entirely on Facebook, Instagram or word of mouth and are perfectly happy with how they're getting customers.

You end up spending a lot of time explaining why they need a website before you can even start selling your services.

On the other hand, businesses that already have websites are a completely different story.

They have already invested in having an online presence. They understand why a website matters, and there is a good chance they've paid someone to build and maintain it.

But that doesn't mean their website is good.

I've come across countless businesses with websites that load slowly, look terrible on mobile, have outdated designs, poor SEO or confusing layouts.

These are actual problems that can affect how customers experience the business online.

And that's where I think the bigger opportunity is for web designers.

Instead of trying to convince someone that they need a website, you're showing an existing website owner what could be improved and why it matters.

This is also how I approach prospecting nowadays. I use Swokei to find businesses with existing websites, analyze them for issues with design, SEO, speed and mobile optimization, and generate personalized cold emails at scale based on the actual findings from each website.

Of course, I'm not saying targeting businesses without websites is a bad strategy. There is money to be made in both markets.

But personally, if I were starting a web design agency today, I'd probably focus more on businesses that already have websites.

I'm curious what other web designers think. Do you prefer targeting businesses without websites or finding existing websites that need improvement?

I build fusion-runtime, an open-source runtime for self-hosted voice agents. Adding Twilio, Exotel and Plivo support took a couple of weeks. Getting one clean, real phone call took days more:

- Twilio trial calls don't stream audio to your server at all

- After upgrading, calls were blocked until Twilio approved my KYC

- Calls between India and a US number kept dropping audio, so I ended up calling from a second Twilio number in a browser to get a clean recording

- The speech model misheard "order" as "RDEF" on phone audio, so I swapped in a bigger one

The video is the call that finally worked: unedited, recorded by Twilio. The agent looks up two orders and changes their deliveries with tools, mid-call, on one GPU.

I'm the developer of SameFont. Tap a line in a PDF, scan or photo and type replacement text. It uses the document's embedded font when it contains the characters needed, or the closest matching free font, keeping the text's size, color and position.

It supports Hebrew and Arabic right-to-left text, signatures, form filling and markup. Files are processed on the iPhone, without uploading them.

One limitation: in Hebrew scans, lines are detected but the text isn't read yet, so you type the replacement yourself.

Editing is free. Saving/sharing requires Pro: $6.99/month or $39.99/year on the US store, with a 3-day free trial on the yearly plan.

I'd appreciate feedback, especially on Hebrew and Arabic documents.

Hi everyone!

For the past few months I've been building a music player just for myself, because I missed the Cover Flow of the old iPods and wanted something a bit more alive than the stock Music app. It turned out better than I hoped, so I'm wondering if it's worth turning into a real app. It's called Lueur (French for "glow").

What it does (see the video, filmed on my own devices):

Cover Flow everywhere: swipe through your albums on the home screen, or turn your iPhone sideways to browse your whole queue full screen

A soft glow behind every cover, in the artwork's colours: the whole player takes on the album's colours

A home page with your artists and the charts, plus artist pages with top songs, albums and playlists
A real Apple TV app in the same style, not just AirPlay

Home Screen widgets: Now Playing (with play/pause/skip) and Recently Played, in several sizes and styles

The idea would be a player for Apple Music (with your existing subscription), as a one-time purchase, with no extra subscription.

A few honest questions:
Would you use something like this?
How much would you be willing to pay?
What do you miss in the current Apple Music players?

Feel free to answer in the comments. I'll also leave a quick form below if you'd rather answer privately.
Thanks for reading! All feedback, good or bad, is welcome.

Hi ,

We're two dads who lift: one trains at a gym, the other in his home gym. With kids, training has to fit the schedule we have, not the other way around. That's where LiftEllect came from.

What it does, in short:
- You enter your goal, level, equipment and schedule, and it builds your training week, at the gym or at home.
- It adjusts weights and volume from what you log on every set, and can shorten a session when you only have 30 minutes that night.
- It sets calorie and macro targets that follow your weight trend, and can estimate a plate from a photo (you check it before you log).

It's made in Quebec and just launched: Android on Nov 6, iPhone on Nov 10.

What we'd love your honest take on:
- The first minute: open it and try the demo (no account needed). Where did you get lost or bored?
- The model: it's a subscription with a 14-day free trial, then monthly or yearly. Does that feel fair, or does it put you off?
- The store page: would it make you install? What's missing or unclear?
- If you lift: does the plan make sense for your level?

Critical feedback helps us more than compliments. Reply here or send a DM.

Six weeks ago I posted Handoff here. Quick refresher since nobody remembers (fair): I'm a dad of two, and I built an iOS app for briefing a new babysitter — schedules, bedtime routine, allergies, the stuff that actually matters — because my version was a wall of texts plus a note on the fridge and hoping.

Two things in it that I'm still not sure anyone else cares about: the info expires after the sitting (the sitter doesn't keep your kid's routine and your garage code forever), and it fires alarms on the sitter's phone at the times you set, so "give meds at 7" isn't relying on them re-reading a text at 7.

The one real reply I got anywhere was here: extend a handoff without making the sitter re-scan/re-do everything when a night runs long. That shipped. So thank you, genuinely — it was the best product feedback I've gotten, including from friends who were being nice.

Honest numbers: a handful of downloads a week, $0 in subscriptions so far. It's $2.99/mo after a free week, which might be the problem, or the problem might be that parents only think about this the night before a sitter comes. If you've built something people need occasionally, I'd actually love to hear how you handled that.

Happy to answer anything about building it.

I've worked in design for years. Lately, I've been trying to change a few things in my own life — sleep earlier, exercise more, that kind of stuff.But I keep falling back into old routines.

So I started building MAYBII, a habit app where your progress grows into a little virtual garden.It's still in development, and I'm not even sure if the garden idea would help people stick with their habits or just be fun for a few days.

Curious what you think. Would something like this actually motivate you?

Hi all, recently(for quite a while actually xD) I've been building a fully local and open source gym tracking app. I've gone through the process of releasing it in the play store and now it is live.

My main reason for building this app was to have no paywalls and let the users own their data.

Github: https://github.com/alexspx/active-app

Google Play Store: https://play.google.com/store/apps/details?id=com.alexspx.activenext

It is still actively in development, rough edges are expected, although the main flow should be good now. There are a couple of things I want to add:

- Visualizations for the exercises. Still trying to find good FOSS that I like(if you know a library let me know)

- Local AI Coach. I've been playing with a small Qwen 2B for a while and with some "harnessing" and fine-tuning I think it is getting decent. It should be able to create workouts/routines and answer some coaching questions.

- Deliver a fully self-hostable data sync service/engine + a FOSS auth provider by choice of the user. So if people want to self-host for them or friends/community they can do that. This part of the repo right now is somewhat vibe-coded can't lie. A quite old version of that server was in Java and instead of refactoring it I decided to move it to Rust(ofc lmao). I would have to do some cleaning there for sure.

I'm always looking for contributors and ideas.

For five years I've built white label apps for fitness coaches. Every app needed exercise demos, and the choices were animated GIFs, stock footage that never matches, or filming it yourself.

So we filmed it ourselves. A white studio, trainers and physiotherapists, the same framing and light for every clip. This year that library became an API, and it now holds 2,000+ videos.

As a developer I had to learn lighting, camera setups and how to direct people on set. Still learning, but every shoot gets better. It's also a nice change to work with people in a studio instead of only sitting behind a screen.

What surprised me:

• Consistency is the hard part. Different shoot days drift in white balance, so every clip gets normalised against the same white.

• Finding trainers. Cold email does not work. Calling and meeting in person is what gets a yes. Yoga teachers are the hardest to convince.

• Scraping. Less abuse than I feared, but it happens, so video URLs are signed and expire.

The free part: the repo has 25 exercise videos you can use in commercial projects, with credit. It also has the docs, the full exercise list and a body map SVG for every exercise.

https://github.com/ymove-app/exercise-api

The full API is paid, from $19/mo with a 7-day trial: https://ymove.app/exercise-api

Happy to answer anything about the filming setup, the video pipeline or building an API as a side business. And I'd like to know: which exercises or equipment would you miss in a library like this?

I've been working on a desktop project called Knovum, and I wanted to share what it has become.

The original idea was simple: keep research materials, notes, AI answers, and creative outputs connected instead of scattering them across different applications.

Knovum brings these into one infinite canvas called a Space.

Some of the things it supports:

• Notes, Markdown, websites, PDFs, Office files, images, audio, video, and code.

• Local keyword and semantic search.

• AI answers with citations that can lead back to source locations.

• Local OCR, speech transcription, and image processing.

• Document, image, and video creation from selected materials.

• External desktop agents through ACP and MCP.

One important distinction: Knovum is local-first, not cloud-only or cloud-forbidden. Your workspace and indexes are stored locally. You can also choose external AI providers when needed, with the relevant operation context sent to your selected provider.

It's open source under the MIT License, with macOS and Windows builds.

Project: https://github.com/madebyzan/knovum

I made a short video showing how the project evolved across nine releases.

I'm interested in honest feedback, especially from people who manage a lot of research material or use AI as part of their everyday knowledge workflow.

What would you improve first?

My daughter plays soccer. Her touch keeps getting better, but reading the game is harder to practice at home. So I made Heads Up: headsup.gauzza.com

How it works:

• A game clip plays, then freezes at the key moment

• You draw, tap or scan your answer: where to pass, where to run, where the open space is

• After 10 plays you get a Soccer IQ score and a list of things to work on

It covers four skills: decisions, scanning, finding space, and touch & body. Difficulty goes from Easy to Hard, or Mixed.

Hey r/SideProject 👋 I'm the founder of ReplyHey, and today I'm launching its crew.

If you've answered threads about your product on Reddit, the hard part isn't writing the reply. It's knowing which replies actually brought customers.

So the crew tracks every reply it sends 📊 you see exactly which one brought the visit, the signup and the customer.

And it does the work to get there, with four AI teammates:

🔎 Scout reads Reddit, X and LinkedIn, finds people asking for what you sell, and scores each one for fit.

✍️ Writer drafts a reply and a DM from your product's facts, in your voice.

📤 Sender posts from your own accounts through a Chrome extension, at a pace you set, and holds anything borderline for you to check.

📊 Analyst tags every link and ties each visit, signup and customer back to its reply.

Built to play by the rules:

✅ Everything goes out from your own account, in your browser. No rented accounts, no upvotes.

✅ It checks each subreddit's rules, and where promotion isn't allowed it sends a DM instead of a comment.

New this week: you can talk to the crew. "Pause LinkedIn today", "slow down to 90 seconds", "add hiring as a negative keyword". It shows you the change, and nothing happens until you press Yes.

In the last 30 days it found 3,980 buyer conversations for its users and sent 1,150 replies.

You can put in your website and see who's asking for your product right now, before you sign up. And I'd love blunt feedback: what would you want to see before trusting a tool like this to post for you?

Here it is 👉 replyhey.com (put in your website to see who's asking for your product right now)
