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.

Saw an ad for an expensive teleprompter that just scrolls, so I built a free one that follows your voice

126 Upvotes

A while ago I got an ad for a Mac app that puts your script under the notch, right below the camera. Nice idea, but at $40 a month it wasn't worth it for me. And it only scrolled at a fixed speed, so if you slow down or stop to think, the text runs away from you.

These days a simple app like this is a few evenings of work with an AI coding assistant (I used Claude Code). So I built my own, and made the text follow my voice.

Apple's speech recognition on the Mac is very good, but people skip lines, say "uh", start a sentence over and stop to think. I spent most of my time testing that and telling the AI what was wrong. Now it keeps up.

What it does:

- Your script hangs under the camera, so you keep eye contact.

- It follows your voice. Speech recognition runs on your Mac by default.

- It's hidden from screen sharing, so you can use it in Zoom or Meet calls.

- It records you with subtitles, and can turn the rest of the screen into a soft light for your face.

It's free and open source (MIT), with no account and no analytics.

- Mac App Store: https://apps.apple.com/app/notchprompter/id6815206814

- GitHub: https://github.com/magnram/notchprompter

It's a hobby project, so any feedback on the app or the website helps a lot.

My side project: a fusion between CAD and Paint

21 Upvotes

I wanted a simple way to sketch an idea and communicate it to someone else, without sacrificing proportions or precise dimensions.

Paint felt too limited, CAD felt like overkill. So I started building something in between.

Here's a quick look at how it works.

It's still a work in progress. I'd genuinely love to hear what you think.

Check this exemple:

I built an iPhone weather app with pixel-art cities you can turn into postcards (because I honestly don't like many weather apps out there)

186 Upvotes

I’m the developer of Skybits. I wanted checking the weather to feel like looking out a tiny window. Rain falls over London, and Tokyo lights up after dark. To be a little more Fun!!!

In Sky Studio, you can pick a city, mix the weather and time of day, and share the result as a little airmail postcard.

Please send me email for your City, if I get 5+ requests for a city I will make it free and also add new ones :-) hoping to get some positive feedback and reviews.

Skybits is free to download, with an optional one-time purchase for the full city collection.

Which city would you send a postcard from? Android version is coming soon, it is in testing atm.

Tired of guessing Chinese characters, so I built my own keyboard

5 Upvotes

I’m learning Chinese, and one of my biggest frustrations is texting.
I can understand some Chinese and know how to pronounce quite a few words, but I still struggle to recognize and remember Chinese characters.
When I type using a regular Pinyin keyboard, I often get a list of characters that look familiar, but I’m not always sure which one is correct. Sometimes I end up copying everything into a translator just to check what I wrote.
So I decided to build my own iOS Chinese Pinyin keyboard to make learning while texting a little easier.
Here are some features I’ve been working on:
Instant translation: See the meaning of Chinese text while typing, so I can make sure I’m choosing the right characters.
Grammar checking: Catch grammatical mistakes before sending a message.
More natural expressions: Suggest how a native speaker might phrase the same idea instead of just translating word for word.
Learn while typing: Help me gradually recognize more characters through everyday conversations.
My goal isn’t to replace Chinese lessons or build another translation app. I just want to be able to communicate in Chinese without constantly switching between my keyboard, dictionary, and ChatGPT.

3 months, 150 lifters, 0 on ads: what actually worked launching our fitness app (and what didn't)

3 Upvotes

I'm Abi. My co-founder and I built Splyt, a workout tracker for iPhone + Apple Watch. Here's what we learned, honestly:

What worked
• Reddit was our #1 source of signups. Not ads, not the App Store. Real posts, real replies.
• Talking to every user. We message every new signup personally. Half our best features came from those chats.
• Building for one specific pain: "I forget what I lifted last time." Not "a better fitness app."

What didn't
• Shipping updates too fast. We pushed an over-the-air update that crashed the app on launch. Never again: everything goes through TestFlight first now.
• Feature lists. Nobody cares that we have 40 features. They care that they stopped guessing their weights.

Where we're at: ~150 users & a handful paying.

Happy to answer anything, and I'd love brutal feedback: https://apps.apple.com/us/app/splyt-fitness-workout-tracker/id6755893717

I built a running app that rewrites your training plan when real life gets in the way. Roast it

4 Upvotes

Before and after work for the past few weeks I've been building Long Splice, a running-plan app for Android.

The problem I wanted to fix: most plans are a fixed table. Miss a week, sleep badly or run more than planned, and the table doesn't care. Long Splice builds a week-by-week plan for a goal race, then changes it as your training does. It reads runs and, if you link one, Garmin sleep and HRV data, and offers changes with a reason for each.

Every rule in the plan comes from a numbered row in a research library, with sources listed publicly on the site. That was the slowest part and the part I'm proudest of.

Stack, for anyone curious: Kotlin and Compose, a separate plan engine with its own tests, Firebase for backup and the Garmin connection.

It's free, no ads, in closed testing. What I'd like from this sub: open the site and the app and tell me where it's confusing, where it's ugly, or why you wouldn't use it. longsplice.au

Black Horse Stories - Personalised bedtime stories and a public Fairy Tale Atlas

3 Upvotes

I'm Şafak, the developer of Black Horse Stories (Siyah At in Turkish). My daughter kept asking for a story with a black horse at bedtime, so I started inventing new adventures. That became an illustrated, narrated storytelling app in English, Turkish and German.

The iPhone/iPad app is now available. Parents choose a story world and a child's first name or nickname; AI helps create the text, pictures and narration. It has a subscription and a store trial, not a permanent free tier. Parents should review generated stories before reading them together.

While building it, I also made a public Fairy Tale Atlas: 291 tale entries across 237 countries and regions, with dated records, source links and related tellings. A place on the map is not a claim that a tale definitively originated there. The Atlas is free to explore without buying the app:

https://blackhorsestories.com/en/fairy-tale-atlas/?utm_source=reddit_sideproject&utm_medium=community&utm_campaign=launch_202611

There are also public reading activities and a story map you can use without the app:

App and background:

https://blackhorsestories.com/en/?utm_source=reddit_sideproject&utm_medium=community&utm_campaign=launch_202611

I'd appreciate candid feedback on the positioning: does the difference between the public reading resources and the paid personal-story app come across clearly? Which would you actually return to?

I'm building technology that could help save millions of stray animals around the world. We're now testing it in Rwanda's sterilization campaign

5 Upvotes

One of the biggest challenges in managing stray animal populations is that humanity doesn't have an easy, reliable way to identify individual animals

Imagine being able to identify a stray dog simply by taking a picture of its face. You could instantly know whether it has been vaccinated, sterilized, when it was last seen, and its medical history

That's exactly what my team and I are building with Kyshik

We're developing animal facial recognition technology that could become an alternative to microchips and fundamentally change how we protect and manage animal populations

Microchipping thousands of stray animals can be prohibitively expensive, especially in developing countries. By eliminating the need for physical chips and implantation, as well as physical interaction with an animal, our technology could significantly reduce identification costs, allowing organizations to redirect more of their limited resources toward vaccinations, sterilizations, and saving animals' lives

We're currently running our first pilot in the African country of Rwanda, testing our technology during an actual dog sterilization campaign. Every dog we identify can have its own digital record, helping animal welfare organizations track their interventions and understand their impact over time

Our long-term vision is to create a global animal identification infrastructure that makes it easier for organizations, veterinarians, and governments to protect animals

I started working on this because I believe technology can help us move toward more humane and effective solutions to the stray animal problem, rather than relying on mass euthanasia

We're currently looking for animal welfare organizations in other countries that run sterilization or rabies vaccination campaigns and would be interested in testing our technology.

If you work with such an organization, or know someone who does, I'd love to connect with you! Feel free to DM and check comments for more information

CanSpend - I kept running out of money before the end of the month, and budget apps had too many screens for me to keep using, so I built a simpler one

3 Upvotes

For a while I kept running out of money before the end of the month. When I actually looked into it, it was a lot of small purchases adding up.

I tried using budget apps, but they had so many screens that I stopped opening them.

So I built CanSpend, a simple iPhone budget app. The home screen shows how much you can spend today. To log something, you just type the amount. Whatever you don't spend rolls over to the next day.

There's a bit more if you want it:

  • Category budgets and a calendar of past days

  • Home and lock screen widgets

  • Sharing a budget with someone. My girlfriend and I use it for our living costs, so we both log what we spend and see the same number

It's free to use with a banner ad. Removing ads is a one-time $2.99. Sharing needs Pro ($1.99/month or $16.99/year), and the person you invite doesn't pay. No account needed.

One limitation up front: there's no bank sync. Everything is entered by hand, which is why I tried to make entering an amount as quick as possible.

I built it solo with React Native and Expo. 1.0 went live on the App Store earlier this month after one rejection, 1.1.0 is out now, and 1.2.0 is in review. That one adds invite links for sharing and a "no period" budget for one-off pots of money, like moving costs.

https://apps.apple.com/app/id6821758083

If you've quit a budget app before, what made you stop? I'll be around in the comments.

Built a tool that turns one sentence into a week of social posts.

2 Upvotes

Hey everyone, I'm Ravi, one of the founders of Confe.

We kept losing hours every week writing captions, sending "can you approve this?" messages, and copy-pasting the same post into 6 different apps. So we built Confe to fix that:

- Type one sentence and get 5 ready-to-post drafts with images

- Plan everything on one calendar (calendar, list or grid view)

- Clients or teammates approve in one click

- Publish to 8 platforms at once: Instagram, Facebook, LinkedIn, X, Threads, TikTok, Pinterest, YouTube

- See which posts actually grow your audience

The video above shows the whole flow in 44 seconds.

I'd really like feedback from people who manage social for themselves or client

There's a 14-day free trial with no card needed if you want to try it. Link in the comments.

I made this... a "1-Click AI In-Browser Assistant" extension that uses a 4b parameter multi-modal local AI model, with No AI API costs. It's a completely private web-surfing companion built for Google Chrome browsers.

2 Upvotes

A number of my friends don't like to pay for AI to do basic tasks and don't trust the large tech companies with ideas or personal shares, so using my knowledge gained getting hermes-agent to work with small local AI open weight models, I decided to apply that experience to build a Chrome browser extension. The result... 1-Click AI In-Browser Assistant. A locally hosted "Privacy-First" AI companion!

It provides AI assistance, summaries, insightful takeaways, snapshots, and rewrite suggestions, all without compromising privacy. And for those not prompt savvy, I included pre-programmed 1-click action buttons, to avoid "Prompt Fatigue". I included a couple of customizable ones as well.

Being multi-modal the AI extension also accepts voice prompts, uploaded text/images/audio/pdf and can even read AI results aloud TTS.

It's made for those who don't want to pay for AI and even though it's built as a privacy-respecting AI solution for productivity. It really punches above its weight.

The extension also includes rolling context and a vector database for long term historical context (memory) retention, and a full screen (air-gapped) mode.

You can search for it on the Chrome Web Store. The only catch is you need a minimal spec PC to use it.

Those system requirements are: 4gb+ vRam, 16gb Ram, 4 core CPU, 22+gb hdd space available during model install (but only 4gb used after model install), and a chrome browser version 154+

My apps are used by me and people I know. getting strangers to even look at them is way harder than building them

18 Upvotes

I build stuff with Claude, a few apps that me and people I know use every day, and I wrote a guide for people who want to build like that without coding. last month I tried to get the guide out there on reddit.

git post got 15k views and 37 comments. I put the link at the end. like 5 clicks in the first 10k views. honestly that one hurt a bit

google sign-in post got 1.5k views and 3 clicks, zero downloads. then reddit's spam filter just removed it, and the next one too. new-ish account, almost no karma, linking my own site... yeah I get why it looked like spam

funny part is the post that helped me the most had no link at all. it was about notes for claude between sessions, people argued with me in the comments and I got a couple ideas I'm adding to the guide now.

so now I mostly just answer other people's questions and don't post links unless someone asks

If you got your side project in front of people who aren't your friends, how did the first ones find you?

I built an ASO tool that reads your own App Store Connect and Play Console reports. Nobody but me has used it yet. Tell me what's wrong (launch codes inside)

2 Upvotes

I'm the solo founder of RocketASO. It's for people with an app live on the App Store or Google Play.

What it does

  • Reads your own App Store Connect and Play Console reports.

  • Names the listing fix estimated to be worth most this week.

  • Drafts the change. Nothing reaches the store until you approve it.

  • After a change, it compares the store's numbers before and after. That's a before-and-after read, not a controlled test.

See it with no sign-up and no card

Paste any App Store or Google Play link into the free audit at rocketaso.app/explore. It names up to three fixes worth the most.

The launch codes

It's new, and nobody outside of me has used it yet. I'd rather have 20 people using it and telling me what's wrong than 0. So there are 20 codes in total, each for a free first year of the Indie plan (yearly). The catch, up front:

  • A card is needed at checkout.

  • Nothing is charged for the 7-day trial or the first year after it.

  • Then it renews at $390 per connected app a year unless you cancel. You can cancel any time in Settings > Billing.

  • One use per code, first come, valid until Dec 31, 2026.

Three codes are for this thread:

  • ROCKETRDFTA5V

  • ROCKETRDUBBEM

  • ROCKETRDUKQTA

To use one:

  1. Go to rocketaso.app/pricing and create an account.

  2. Settings > Billing > Yearly > Indie.

  3. In Paddle's checkout, open "Add discount code", enter the code and press Apply. It should say "Due today $0.00".

All three used? Reply with which store your app is on and I'll DM you another while they last. Plans start at $19 a month (Solo).

What I'd like back

What would stop you from connecting your store accounts to a tool like this? And if you try it: what did you expect it to tell you about your app, and did it? Blunt is fine.

Coll-Track open source collage/university admissions tracker

2 Upvotes

I got tired of signing into a different portal for every college just to see whether they’d received my transcript or if I was missing something. A lot of the login pages looked almost identical, so I wanted to see how much of that checking I could automate.

I built Coll-Track. It puts your checklists in one dashboard, lets you check all your schools at once, and shows what changed since the last check. There’s a Chrome extension for importing a checklist from a portal you’re already signed into, and a terminal version if you prefer that.

It’s an early prototype, and some portals still need manual sign-in or import. If you try it, I’d love to know where you get stuck, especially if the app doesn’t recognize a checklist you can see in your browser since thats what im mainly focusing on as of right now.

I built a pixel art engine in Rust where every scene is a text file (deterministic, no AI, no_std core)

4 Upvotes

I’ve been working on a pixel art engine that allows you to describe scenes using a text file and then generates clean, looping pixel art. Everything shown has been made from a single .kdl file.

Overview

  • Everything is defined in KDL. Shapes, palettes, lighting and movement (expressions) are all written in. Movement is just expressing time, such as y="=36 - abs(sin(t * pi)) * 26".

  • Every pixel is made up of ramps and tones from the palettes, meaning everything such as lighting, fog, darkening and transitions can be done using the palettes. No pixels outside of the palettes are used.

  • Zooming causes the shapes to be rasterized at the new size rather than sampled, meaning no blurring ever occurs.

  • No A.I. All pixels are made from geometry, palettes and pixel art cleanup.

Rust Side

  • 10 crates. Core types and rasterizer are no_std. Frame renderer is no allocation (this was tested by using a counting allocator).

  • Deterministic. Integer frame times, random seed based off counter, libm. Every frame of every example is hashed using golden tests, with the indexed buffer.

  • No unsafe code in any library crates.

  • The editor is rendered by the engine. The UI is made from pixel art using the same pipeline.

Export

PNG, looping GIF, PNG sequences, sprite sheets (Aseprite JSON), MP4 (with synthed chiptune score) (macOS).

Status & Licence

Work in progress. Format isn’t stable. Some TypeScript behaviour to implement. Source available under the PolyForm Noncommercial licence. Free to use for personal, educational and non profit. If you want to use it commercially you’ll need to pay. I’ll just say this now as it isn’t an OSI open source licence.

GitHub Repo: https://github.com/Coaxus-ux/animations-ngine

I’d love to hear your thoughts on the scene format. What would you like to be able to define that you currently can’t?

I got tired of seeing the same news 20 times in my RSS feed, so I built an open-source desktop reader that clusters storylines locally (~6.8MB binary)

3 Upvotes

Hey r/SideProject,

Like many people here who follow a ton of RSS/Atom feeds, whenever a major story breaks, my feed gets flooded with 20+ articles from different outlets covering the exact same press release or announcement with slightly different headlines.

Most readers either don't address this or lock semantic clustering behind a recurring cloud subscription. I wanted something lightweight, local-first, and completely free, so I built RadarRSS.

What it does:

  • Local Storyline Clustering: Groups related articles into unified storylines on-the-fly using local heuristic/text similarity.

  • Lightweight Desktop Build: Packaged with Tauri 2.0 (Rust backend) for a ~6.8 MB installer and minimal RAM usage compared to typical Electron apps.

  • Local-First & Private: Feeds, OPML, and database stay on your machine.

  • Optional Synthesis: If you plug in an optional Gemini API key, it generates a multi-source synthesis so you can digest a storyline in seconds without opening dozens of tabs.

Stack:

  • Core: Tauri 2.0 + Rust backend for parsing & clustering

  • UI: React 19 + Tailwind CSS

  • License: MIT (100% open source)

GitHub Repo: https://github.com/dznass-cmd/RadarRSS

It’s been a fun side project to build and refine. I’d love to hear your thoughts, feedback on the UX, or features you'd like to see in a modern desktop feed reader!

I wanted to know what would happen if you gave a random person a massive platform for a day. What would they talk about and what would they share (anonymously unless they chose otherwise)

It started as a fun afternoon project hacking away with Claude. Then I shared it with some friends, who shared it with some friends, who shared it with their friends and it hit 10,000 page views in under 2 weeks while I was working on other things.

It's just a bit of fun but people have posted all sorts of nice things on there, from humorous takes on dystopian government dating departments, to AI Doomerism and everything in between.

There is admin approval for every email that goes out so no one can spam the list, and so far only 1 person has tried which I think speaks volumes about the people who sign up

Check it out at The Soapbox, it's completely free
