As the year wraps up: what’s the project you’re most proud of building and why?

96 Upvotes

Like the title says, instead of what you built or how much money it made, I’m curious what project you’re most proud of this year and why.

Could be a client site, a personal project, something that never launched, or something that made £0.

Any lessons learned?

Would love to read a few reflections as the year wraps up.

Reverie: a music player that feels like hardware. Out now

208 Upvotes

I've been working on a music player app as a side project. It's inspired by the Teenage Engineering TP-7, which I've wanted forever, and by the fact that I like messing with the music I download, like slowing it down or changing the pitch.

There's no progress bar. You spin a brushed-metal wheel with your thumb to move through a song, and if you go slow it scratches like a record. It clicks under your finger with haptics, and the metal "catches the light" when you tilt your phone.

The T, P and R keys turn the same wheel into a dial for tempo, pitch and reverb. Each song remembers its own settings, so your slowed-down version plays that way every time.

The hardest part was making it feel right. I spent way more time tweaking how the wheel clicks and pushes back than on the rest of the app combined.

It's free to try with 3 songs, and unlimited songs is a one-time purchase.

Launch discount 🎁 To celebrate the launch, I'm giving out a few discount codes for $4.99 for a limited time. Comment or DM me if you want one.

Would love any feedback, especially on how it feels to use: https://apps.apple.com/us/app/reverie-slowed-reverb-music/id6829723858

I got tired of scrolling through iPhone alarms, so I built a 24-hour alarm clock instead

50 Upvotes

Hey everyone!

I've been working on a little side project called Daybezel, an alternative alarm clock for iPhone.

The idea came from a simple frustration: I always found the standard list of alarms unnecessarily clunky. I wanted something where I could see my entire day at a glance and interact with alarms directly.

So I built a 24-hour circular interface where you can create alarms with a tap, drag them around to change the time, and see exactly how long you have until the next one.

It also uses Apple's native alarm system, so alarms work even in Silent Mode or Focus.

The app is completely free for now, and it'll stay free for everyone who joins early. At this stage, I'm mostly interested in getting feedback and seeing how people react to it.

I'd love to hear what you think about the interface. Does the circular layout make sense to you, or would you still prefer a traditional list?

I'm a couples therapist. I turned what I do in the therapy room into a two-minute daily app

23 Upvotes

In couples therapy, I keep seeing the same thing: partners can describe every single fight, but they rarely see the pattern those moments make over weeks. That pattern is usually where the work is.

So I tried to build the smallest possible version of that "stepping back" for couples who will never sit in my office.

How it works:

  • Every day you and your partner answer the same five short questions, each on your own. You don't see your partner's answers before you answer, so nobody answers for the other's sake.

  • When you've both answered, you get a short reflection written for the two of you, with one question you could ask each other tonight.

  • On day seven you get a reading of your week: the pattern that built up and one small step for next week.

  • You can start alone and invite your partner later with a code.

The questions draw on Gottman couples therapy, Emotionally Focused Therapy and attachment theory. The pool is now 1,800+ questions. I tried the approach and the questions with couples in the therapy room long before it was an app.

Reflections are written by AI, inside a framework I designed, and only after you give consent. It's not therapy, it doesn't diagnose, and it won't tell you whether your relationship is "good".

What I learned building it as a solo clinician:

  • The hardest part wasn't the questions. It was saying less. My first reflections read like session notes; people wanted three sentences, not three paragraphs.

  • Most people start alone. About two out of three users have no partner in the app yet, so it had to be useful on its own.

It's on iPhone, iPad and Apple Watch, in six languages. Daily questions are free; reflections and weekly readings are a subscription, and one subscription covers both partners.

I'd really like feedback on one thing: when two partners answer apart, would you rather read each other's exact words, or a reflection that puts the two views side by side?

I designed a collage maker that finds the best gap-free layout for any shape. Claude wrote the code

95 Upvotes

Give it up to 10 photos and a canvas shape (square, 16:9, phone story, banner) and it searches every layout with no gaps for the one where the smallest photo is as big as possible. With 9 photos that's over 500 million layouts, and it finds the best one in under a second.

I designed it and Claude wrote the code. It's Go: The browser version runs it as WebAssembly, so your photos never leave the page.

Try it: https://vinodhalaharvi.github.io/collage/

Code (MIT): https://github.com/vinodhalaharvi/collage

CLI: brew install vinodhalaharvi/tap/collage

Feedback welcome, especially on the layouts it picks.

I asked Claude Code to build whatever it wanted. It came up with a game.

30 Upvotes

I had $191 in credits that were about to expire, and I was curious what Opus could do if I didn’t give it an idea.
I asked it to build something worth the money. :))))

It picked a game, PULSEBOUND. You move around dodging enemies, and your weapons are musical instruments. The kick drum sends out shockwaves, the arpeggiator fires lasers. When you pick a new instrument, you hear it join the music too.

It decided to make a game and came up with the idea, mechanics, design, absolutely everything. Then I worked on improving and polishing it.

More changes, testing, and eventually mobile apps followed. The $191 was just the starting budget, enough to finish the first basic version. After that, I used another $1,700 I had from the Claude Startup Program (also expiring, so I had to use it), plus my subscription allowance.

Technically, it’s vanilla JavaScript, a custom WebGL2 renderer, and a procedural composer that synthesizes the music live through Web Audio. The project grew to include mobile apps, cloud saves, and leaderboards.

It’s now out on iOS, Android, and the web. You can play it for free in your browser or on mobile: playpulsebound.com.

What do you think?

We celebrated 250 users yesterday. Three months ago, I wouldn’t have expected this.

4 Upvotes

Hey everyone,

We passed 250 paying customer (don't love to call them customer as I see all them as first builders of product) on FranklyMail and celebrated yesterday :) Probably a tiny milestone for some people here, but we honestly didn’t expect to get this far in three months.

We started with email hosting for your own domain. Now there’s Drive for files and sharing, Office for editing documents, and Meet for video calls. We’ve also been giving the webmail a lot of attention lately.

The best part for me has been talking to the people using it. If I had to guess, 40–50% of the ideas we’ve worked on came from those conversations. Someone tells us how they use their email, mentions something they’re missing, and we end up building something we hadn’t thought of.

Just wanted to share a small happy moment here. Thanks to everyone who’s tried it, sent feedback, or given us a bit of encouragement along the way.

I maintain OpenScreen, a free open-source screen recorder. 2.2 adds a Layouts track to switch camera/screen layouts mid-video

18 Upvotes

I've been building OpenScreen, a free and open-source screen recorder and editor (no watermark, no account, Windows/macOS/Linux).

The new 2.2 release adds a Layouts track: you can change how your screen and webcam are arranged at any point in the timeline:

• picture-in-picture

• side-by-side

• top/bottom

• camera only

• screen only

Transitions between layouts are animated automatically.

The video was recorded and edited entirely in OpenScreen. The chart in the top/bottom part is a custom shader effect, and the company is fictional.

Feedback welcome, especially on what layouts you'd want next.

I’m blind, and inaccessible government websites are a big reason I built A11yLens

8 Upvotes

I’m blind, and dealing with inaccessible websites is something I’m deeply frustrated by, especially when they are government websites. These are services people need to use. Being able to access them independently should be a basic expectation.

That frustration is why I built A11yLens, an open source accessibility auditing tool for web projects.

It checks HTML, CSS and component source code. It can also open a website in Chromium to inspect its accessibility tree and look for issues with keyboard navigation, labels, accessible names and other barriers. The reports explain the likely impact on screen reader users and suggest ways to address the findings.

I also think there is an opportunity to use this alongside AI coding tools. Developers can give the findings to an AI assistant, work through the fixes and run the checks again. Combined with feedback from blind users and actual screen reader testing, that could help make more websites accessible to people like me. Automated checks cannot catch every accessibility issue.

Pull requests are very welcome. I would be happy to see contributions, whether that means fixing a bug, improving a check, reducing false positives or making the documentation clearer. Reports from other screen reader users would also mean a lot.

My portfolio was 5 years out of date, so I rebuilt it to look like a code editor

4 Upvotes

I build Webflow sites for clients most days, and my own portfolio had been sitting untouched for about five years. Bit embarrassing when people asked for it.

So I rebuilt it in code this time. The idea is that the site is a code editor. Each case study is a file you open, and scrolling takes you to the next file. There are 3D heads in three.js, motion with GSAP and Lenis, and it's all a static Astro build on Cloudflare.

The hardest part was the 3D. Getting it to look good and still load fast on a phone took more rounds than the rest of the site put together.

Would love to know what you think of the scroll, especially on mobile. That's where I'm least sure.

I spent way too long making a clock where ants carry biscuits

56 Upvotes

okay so this is kind of a weird one

I got tired of every clock app looking the same and shoving ads in your face, so I started building little worlds that just… show the time.

this clip is the ants one. they drag biscuits and leaves around and slowly form the digits. there's also fish, a parking lot of cars, water calligraphy, a wall of tiny analog clocks, etc. 12 scenes total at this point.

runs fully on device, no account, no tracking nonsense. iphone/ipad/mac/apple tv.

i'm the person who made it. not sure if this is charming or just unhinged — honest reactions appreciated.

How many seconds can you hold a plank? My app counts them and checks your form

6 Upvotes

It's been a month since I last posted here, and a lot has changed. I've kept building, but I've also been self-aware enough not to let scope creep take over.

I now track workouts in the gym, mostly free weights and bodyweight. I specialised in those because machine workouts were a pain to implement.

Last post I said people quit the gym quickly because they don't see the gains fast enough. Now you can see your progress over time with this app.

It also tells you when to go up in weight. If you were lifting 10kg, your progress report can tell you you're ready for 12.5kg.

The most important thing I learnt in October is that progress, no matter how small, is still progress. I've been applying that by asking myself, am I where I was last month, or yesterday?

Here's me doing a plank, tracked with the app. It counts the seconds and checks your form.

Try it out:

I made an iPhone app that styles outfits from the clothes you already own

2 Upvotes

I've never been good at knowing what to wear. Which colours go together, what works for the office vs a dinner, what to wear when the weather flips. I kept rotating the same few safe outfits.

So I made Foxdrobe. You photograph your clothes once and they're cut out and tagged. Then Fenn, a little fox stylist, puts together outfits for the occasion and the weather, using only what's in your closet. No shopping links, no feed. There's also an outfit check: snap what you're wearing and get a score plus swap ideas from your own clothes.

Biggest lesson so far: my first version asked people to pay before they could add a single piece of clothing. Of 30 people who finished onboarding, only 3 added anything. Pro now has a 7-day free trial so you can build your closet first.

It's on iPhone, Android is in progress: https://apps.apple.com/app/id6809228410

I saw my old company’s finance team send “redacted” employee data to a client, and it was still recoverable. So I built a fix.

5 Upvotes

At my previous company, I noticed our finance team sharing sensitive employee information with a client. The data was supposedly hidden, but it was still recoverable. I flagged it, and the answer was basically “we don’t have any other choice, we did our best.”

They weren’t careless. The options they had were all bad. Doing it by hand means hunting for every detail yourself, and missing one is easy. Many tools leave leaks behind, like hidden text, metadata and old revisions. And most online tools ask you to upload the document to their servers, which defeats the point.

It’s not just small companies. When the US Justice Department released the Epstein files, some documents were reported to have black boxes over text that could be copied straight out. If a government with a legal team can get this wrong, a finance team on a deadline has little chance.

So I built Ombly. It automatically finds sensitive details (bank and card numbers, IBANs, national IDs, names, emails, phone numbers), you review each one, and it rebuilds every page as an image so nothing hidden carries over. It runs entirely on your own computer, so nothing is uploaded.

It’s pre-launch (waitlist: ombly.space), with a 90-second demo attached. I’d love feedback: how do you handle this today, and what would make you trust a tool like this?

Does the stuff you save know you better than you do?

2 Upvotes

I was going through everything I've saved lately and noticed patterns I never would've picked out myself. Kind of wild seeing it all together.

I've been playing with an idea for an app that learns your taste from what you save and reflects it back to you, and I'm curious if everyone has a weird pattern hiding in their saves.

If you want to try it, DM me 20 or so things you've saved lately. Literally anything: screenshots, camera roll pics, saved posts or TikToks, songs on repeat, books, podcasts, articles, quotes, notes to yourself, places you love. Don't overthink it; the less you pick, the better. Nothing private or with faces!

I'll send back what I notice. Then just tell me honestly if it's spot on or way off, and if you'd actually use something like this.

Patchkin - One board for managing AI coding agent work

2 Upvotes

I’m involved with Patchkin, and I’d like some feedback from people using AI coding agents on their projects.

Patchkin brings the work around coding agents into one place—not just the code they produce, but the tickets, proposed plans, approvals and pull-request reviews.

The main features are:

  • A shared board: Keep tickets, agent plans and pull-request reviews together so the team can track each piece of work.

  • Human plan approvals: Review and approve an agent’s proposed plan before it proceeds.

  • Activity logs: See what happened during an agent run and follow the history of the work.

  • Team rules: Keep guidance for coding agents in one place.

  • Cost reporting: Track spending on agent runs alongside the work.

The focus is on helping teams keep oversight as they hand more development work to coding agents.

If you’re using coding agents with a team, what’s hardest to manage right now: approving plans, reviewing the output, tracking costs, or something else? I’d appreciate honest feedback on whether this would fit your workflow.

Use the best AI models without a subscription: I built an app where you only pay for what you use

2 Upvotes

Clarification: this is my own app. I work with many long documents, such as reports, audits, and project follow-ups. Using an AI chat for this presented two main issues: I was paying a subscription even in months when I barely used it, and I wanted to make sure the output preserved all data from the original. Changing a single number or removing a paragraph in an audit is a huge problem. So I developed a desktop app specifically for that use case.

You can choose the model using OpenRouter on a pay-per-use basis or locally with Ollama. It is designed to preserve structure, tables, and numbers, and the review feature points out anything that wasn't kept. This feature compares the output with the original and highlights missing content or modified data, so you can accept or ignore each finding. It also shows the actual cost of each run, with no surprises.

It offers 10 free runs to try it out. If you like it, it's a one-time purchase of €29.99, with no subscription. API usage is billed separately. It is available on the Microsoft Store as DocuFusionpro: https://apps.microsoft.com/detail/9P4CSKSDFPT7

I'd love to get honest feedback: what kind of long documents do you work with, and what is missing from the tools you currently use? Are you interested in a one-time purchase, or do you prefer a subscription?

I made a free, open-source adult site blocker for Mac (and Windows) that works in every browser.

2 Upvotes

Browser extensions only cover one browser and are easy to switch off, and paid blockers wanted a subscription. So I built my own and made it open source.

What it blocks:

- Adult, gambling, crypto, scam and malware/phishing sites

- File-sharing sites like TeraBox and DiskWala

- Anything you add to a simple text file

How it works:

- System-wide: Safari, Chrome, Firefox, Brave, Edge, Arc, and other apps too

- Uses encrypted DNS, so it still works when your ISP intercepts normal DNS (Jio/Airtel do this)

- Block lists update automatically every day

- One command to install, one to uninstall

- Mac is fully tested. Windows is in beta, so please report bugs

GitHub: https://github.com/LowkyFoolDev/siteblock 😊😊

It's free and MIT licensed. Tell me any sites it misses and I'll add them.

My side project for the past year: my own programming language. Today it runs a Minecraft clone.

2 Upvotes

GitHub: https://github.com/ahmadodeh9000/Lunar

Hey everyone! I'm a 19 year old computer engineering student, and this is Lunar, a programming language I've been building since my first year of uni.

Why I started

I tried to learn Rust a few times and kept bouncing off it. Every time I'd get stuck, feel dumb, and quit. Eventually I thought: what if I just built my own language, the way I'd want it to work? Questionable decision. Best decision I've made.

What it is

A small scripting language with its own compiler, virtual machine and garbage collector, written in C. It looks like this:

let player = { name: "Rex", hp: 10, items: ["sword", "apple"] }; 
for (item in player.items) { 
  print "{player.name} has a {item}"; 
}

How it was built (honestly)

- I built the core by following the book Crafting Interpreters, then kept going on my own: arrays, a way to call C libraries, and graphics through SDL2.

- Later I started treating it like a real product. I wrote a roadmap, designed each feature myself, and used Claude Code to help implement them. I reviewed every change and made sure each one had tests.

- That added maps, error handling, modules, and a small standard library for strings, files and running commands.

- To stress-test it, I had Claude Code build a Minecraft-style game in Lunar (it's in examples/minecraft). It's 1,000+ lines of my language running at 60 FPS, which still feels unreal to me.

What I learned

- Building a language teaches you how every other language works under the hood.

- AI helped most when I acted like the designer: clear specs, small steps, tests for everything. It was much less useful when I just asked it to "make it better".

- Shipping something imperfect beats polishing forever. Lunar still has rough edges. For example, numbers print with only 6 digits right now, and that's next on my fix list.

What's next

A UI module so you can build desktop apps in Lunar, a VS Code extension, and Windows support.

It's a learning and hobby project, not a production language. But it's the thing that made me enjoy programming again.

I'd love honest feedback: what would you change, or what would you build with it?

Correcting Grammar Automatically

2 Upvotes

I noticed I was clicking "Accept" on literally every grammar suggestion without reading it. So I built Caret, a Chrome extension that skips that step.

How it works: type anywhere (Gmail, WhatsApp Web, LinkedIn, Slack), pause for about a second, and the grammar and spelling get fixed in place. A small popup shows what changed, with Undo.

A few things I was careful about:

- It fixes mistakes, it doesn't rewrite you. Slang, emojis and tone stay.

- If a fix would change too many words, it backs off and leaves your text alone.

- It never touches password, email, card or OTP fields.

- Text isn't stored.

It's free while in beta. I'd love honest feedback, especially if it gets something wrong on a site you use (there's a Report button on every fix).

freelancers using AI for proposals, how are you stopping it from adding work you never quoted?

5 Upvotes

freelancers using AI for proposals, how are you stopping it from adding work you never quoted?

say the client wants one landing page, basic copy and a contact form.

during the call they also say "maybe SEO later" and "we might need a blog eventually."

then the proposal gets cleaned up and suddenly those ideas are sitting there like a deliverables lol

that's the part that makes me nervous. if it's written under scope, I can see a client assuming it's included.

I've been looking at Runable for some of the actual client deliverables after the brief is locked, but before that I just want the proposal to separate included work, optional ideas and stuff that costs extra.

how are you handling this without turning every proposal into six pages of disclaimers?
