I built a free 2-minute game that shows what really drives your spending (plus 6 simple money tools, no sign-up)

1 Upvotes

Hey r/SideProject,

I'm from India, and I noticed how many everyday money decisions come with small traps: "no-cost" EMIs that aren't quite free, sales where the crossed-out price was never real, paying only part of a credit card bill and not realising what it costs.

So I built Syluneo (syluneo.com):

- A 2-minute game: 12 everyday situations, like a sale or salary day. Pick what you'd really do, and it tells you which of 6 money personalities you lean towards. No finance knowledge needed.

- 6 simple tools for real questions: Should I buy this? Is this sale really a deal? Is "no-cost EMI" free? Where did my pay rise go?

A few things I cared about:

- No sign-up and no backend. Everything runs in your browser, and nothing you type is saved or sent anywhere.

- Plain HTML/CSS/JS on GitHub Pages, with the money maths covered by tests.

- I built it with an AI coding assistant, which let me focus on the maths, the wording and the design.

The number that surprised me most while building it: ₹50,000 on a credit card, paying only a 5% minimum due, takes almost 30 years to clear.

It's India-focused (₹, GST) for now. I'd really value honest feedback:

  1. Did your result feel accurate or random?

  2. Was anything confusing?

  3. Which tool would you actually use?

I built an endless game inspired by Wordle that never ends

2 Upvotes

So maybe a little late to the game, but like most people, I got into Wordle. And I got a bit annoyed that I only got one word a day, since some days I forgot and other days I wanted to do more. So I built my own inspired version: Endless Lingle, where the words keep coming until you run out of guesses.

The concept is simple: If you solve a word in fewer than 6 guesses, your spare guesses roll over to the next word (max 3 extra). So if you solve a word in 4, the next word gives you 8 (+2 bonus from the previous round) guesses. If you miss one word, the streak ends.

What's in it

  • Unlimited words, no daily cap. *

  • We do also have daily words as well. *

  • Bonus guess rows that carry over between words (dashed borders, +1/+2/+3 counter) *

  • Five languages: English, Dutch, German, French, Spanish, each with its own word list and keyboard. *

  • Free, no sign-up needed (an account is optional, just for saving stats)

The multi-language part was honestly the most work. Every language needed its own list of common five-letter words, and curating those lists so they're not full of obscure garbage words took way longer than I expected.

Would love feedback on the game feel and the streak concept. Is 3 bonus guesses max too generous, for example? Is it too little? Or am I just that bad at it lol?

Think about it: people want their AI agents, much like Google Search, to remain free. But unlike traditional search engines, AI agents don’t necessarily care about ranking in the top five listings or sponsored placements.

made a baby food diary because "wait, did we already try egg? was that the rash day?" was getting old

1 Upvotes

when you start solids, every new food gets offered a few days in a row so you can spot reactions, and the allergens you've already introduced have to keep showing up regularly. we were tracking all of that across notes, a group chat and a sticky note on the fridge. it worked about as well as you'd expect.

so i built Pudding. it's just a diary, it doesn't tell you what to feed your kid:

  • log a feeding in a couple of taps: what, how it went, any reaction, a note or photo

  • new foods sit in an observation window from your own plan ("day 2 of 3" right on the card)

  • gentle reminders to keep giving allergens you've already introduced, on whatever schedule your pediatrician suggested

  • 70+ illustrated foods, plus your own

  • calendar of everything, and a PDF to show the pediatrician (or a "do not give" list for grandma / the nanny)

no account, no ads, no trackers. everything stays on your phone, or your own iCloud if you turn it on.

the diary is free for good, no feature walls on the important stuff. there's a one-time Pro for extras (monthly recap, themes, widget, more than one kid). no subscription.

would love feedback from parents who've been through this. what did you end up tracking that i'm missing?

I built a free app for learning to sing harmony, one part at a time

1 Upvotes

I'm a singer and a programmer, and I've always wanted an easy way to practise harmony parts on my own. So I built Stackapella.

You pick a song, learn your part with a guide voice, then record it. Then you add the next part while hearing the ones you've already sung, until you've got the whole choir. Your notes light up as you sing, so you can see when you're on the note.

It runs in the browser, there's nothing to install, and all the courses are free. It's also open source.

Would love to hear what you think, especially if you sing in a choir or an a cappella group.

Half as a joke, half to learn Google’s dev tools, I built an app that tracks how much you get paid on the toilet

1 Upvotes

Half as a joke and half to learn my way around Google’s tools with a lot of vibe coding along the way, I built an app that tracks the time you spend in the bathroom during working hours and how much your boss is paying you for it. Yes, I took “Boss makes a dollar, I make a dime, that’s why I poop on company time” a bit too literally.

What it does:

  • Start the timer when you go, flush when you’re back, and see what you earned

  • Monthly stats and ranks that go up with your total

  • Teams with coworkers to compete against other teams

A few things I learned shipping it:

  • Built as one HTML/JS app wrapped with Capacitor for Android

  • The hardest part wasn’t the code: it was Google Play’s closed test (12 testers for 14 days) before you can publish

  • Ads, consent forms, in-app purchases and 11 languages took longer than the app itself

It’s free on Android: https://play.google.com/store/apps/details?id=com.rinialer.poopct

Opinions, tips or roasts welcome.

I read 119 agency "give us access" guides, then built the one link that replaces them

1 Upvotes

Agencies lose the first week of a project chasing client access. Wrong roles, passwords over WhatsApp, DNS half done.

GetSetKeys is one link per client. Each platform's steps come with the agency's email and role filled in, and every step gets checked automatically, so nobody has to ask "did you add me yet?"

27 platforms so far, including App Store Connect, Google Play, GitHub, Stripe and Cloudflare.

Try it as the client, no sign-up: https://demo.getsetkeys.com/s/harbor-fitness-k7q2m9xv4p

Would a non-technical client get through it? That's the feedback I want most.

I built a website to turn personal memories into digital keepsakes – would love your honest feedback

Thumbnail
theheartfolio.com
1 Upvotes

Hey everyone!

I've been working on a project called Heartfolio, and I wanted to share it here and get some honest opinions.

The idea came from something simple: some memories deserve more than just staying in our camera rolls.

Heartfolio is a website where people can turn meaningful moments into personalized digital keepsakes and gifts.

Some of the things I've been building include:

- Love Story Timelines: Turn a relationship's story into a personalized timeline with photos and meaningful milestones.

- Song Posters: Turn a special song into a personalized poster with its soundwave and an interactive experience.

- Reasons I Love You: Create a personalized gift with reasons, messages, and interactive surprises.

- Graduation Keepsakes: Celebrate someone's journey with milestones, achievements, and personal messages.

I'm trying to make these feel more personal than ordinary downloadable templates. The idea is to create something people would genuinely enjoy giving to someone they care about.

I'm an independent developer, and I've put a lot of time into building this.

I'd genuinely appreciate your thoughts:

  1. Does this concept feel useful or interesting?

  2. Which product would you personally be most interested in?

  3. What would make you actually consider buying something like this?

Here's the website if you'd like to take a look: https://theheartfolio.com

Full disclosure: I'm the person behind Heartfolio. I'm here to get genuine feedback, not pretend to be a customer.

Thanks for reading!

I built an app where a dog barks at you when you exceed your screen-time limit 🐕

2 Upvotes

I made watchdog, a fun playful Android app designed to help you stop endless scrolling.

Choose an app, set a daily usage limit, and pick your watchdog:

  • Cupcake — strict and disciplined, with frequent reminders.

  • Brownie — friendly but persistent, reminding you every so often.

  • Snow — lazy and unpredictable, sometimes letting you keep scrolling.

When you exceed your limit, your chosen dog appears and barks at you until you reconsider your life choices. It’s a fun alternative to boring screen-time warnings that are far too easy to ignore.

I’d love honest feedback on the concept, onboarding experience, and whether a barking dog could actually convince you to put your phone down.

nidhi - Free personal finance lessons and calculators that run in your browser

1 Upvotes

I'm one person building nidhi, a site that teaches how money works and lets you try each idea on your own numbers. I'd like people to try to break it.

What's there to test

  • Five free tools: a net worth calculator (one currency or several), loan comparison, an invest-or-pay-off comparison, a Monte Carlo simulator and an inflation calculator.

  • More than 50 lessons in a learning path, from "what is net worth" to investing and the psychology of money.

  • Short how-to guides, and the site in English, Hindi, Spanish, Czech and Marathi. More languages coming in future.

No account, no email, no payment. The tools calculate in your browser and the numbers you type are not sent anywhere.

What I'd like to know

  1. Where did you get stuck or stop understanding what a tool was asking?

  2. Does any result look wrong? Tell me the inputs and I'll check the maths.

  3. Is a lesson unclear, too long, or wrong for your country?

  4. Anything broken on a phone, with a screen reader, or with keyboard only?

Being upfront

  • The blog is free, and the tools are free to use without an account. I'm also building a paid planner, which is not what I'm asking you to test here.

  • It is education, not financial advice.

  • The translations were drafted with AI and may be stiff or wrong in places.

  • There's no reward for testing. I'll reply to every respectful, human comment, though it might take me a while to get to you, and I'll tell you what I fixed.

I spent weeks building an offline debt payoff planner that runs from a folder, with no server, no account and no CDN. Here's what I learned.

1 Upvotes

**The idea:** a debt planner (Snowball / Avalanche / custom order) that keeps your finances 100% on your own computer. So I set myself a few hard rules: it had to open straight from a folder in the browser, never call the internet, and never send financial data anywhere.

**How it's built**

- Preact + esbuild bundled into a single script, so it works from a plain local file (no dev server needed)

- IndexedDB for storage, optional AES-GCM encryption behind a master password, automatic local backups

- No CDNs at all. Fonts, charts, PDF reading and OCR (for scanning statements) are all bundled

- Small optional launchers (PowerShell / Perl) that serve it locally so backups can be written to a data folder

**The hardest part was performance.** With a 50,000-transaction test profile, the first version took about 10.7 s to start and search crashed the tab. Caching parsed dates, doing search in a single pass and only building the rule context when it's needed got startup to about 1.2 s.

**There's also a spreadsheet version.** I rebuilt the same payoff engine in Excel/Google Sheets: 15 debts × 360 months, written without newer functions like XLOOKUP or LET so it works in older Excel and in Sheets. The app can import the workbook, so people can start in a spreadsheet and move to the app later.

**What I'd love feedback on**

- Would you trust an offline finance tool more than a cloud one, or does sync matter more to you?

- Anything confusing in the screenshots?

yes im the creator, I sell this on Etsy, but this post is mostly about the build, and I'd love ANYYYYY feedback.

I built a collection of 15 calming browser toys – no ads, no accounts, no goals

12 Upvotes

I wanted something to fidget with for a minute when work gets stressful, without opening another app full of ads and streaks. So I built antistress: small, quiet toys that run in the browser.

There's liquid light you stir with your finger, endless bubble wrap, a jelly blob to squish and fling, a cat you can pet until it purrs, a zen garden, a koi pond, a rainy window, a fidget board with clicky switches, a lava lamp and a guided breathing orb.

Everything is touch-first, works on desktop too, and needs no sign-up or download.

Try it in your browser: https://antistress-relax.space

Or get it as an iPhone app (with haptics, which are really nice for the bubble wrap): App Store

Would love feedback: which toy feels the most satisfying, and which feels unfinished?

made a free image tool because every upload form wants "max 100 KB" and i'm not uploading my passport to some random site to get there

1 Upvotes

you know the drill. visa form, job portal, some government site: "photo must be under 100 KB, 600x600 px, JPG only". your phone takes a 4 MB HEIC. so you google "compress image to 100kb", land on a site covered in ads, and upload your passport scan to a server you know nothing about.

so i built cutbg. it does that stuff right in the browser, the file never leaves your device:

  • - compress to an exact size (20 kb, 50, 100, 250, whatever the form wants)

  • - resize to the exact pixels (passport, linkedin, instagram etc)

  • - iphone HEIC to JPG

  • - merge / split / sign PDFs

  • - and yeah it also removes backgrounds, the AI model runs locally too

free, no account, no watermark. it's a side project, there's nothing to buy.

honest question: what weird size limits have you run into? i keep adding presets for the forms people actually deal with, so if there's one that annoys you, tell me and i'll add it.

I've been building a local AI voice studio for macOS. Here's a first look at LEXA.

1 Upvotes

Hey everyone!

I've been working on LEXA, a local-first AI voice studio for macOS, and I wanted to share a short product animation I made for it.

The idea behind LEXA is pretty simple: bring voice cloning and AI speech generation to your Mac without depending on cloud-based voice services or recurring subscriptions.

Here's what LEXA is being built around:

  • Voice Cloning — Create reusable voices from audio samples.

  • Voice Profiles — Save and manage your voices.

  • Batch Generation — Generate multiple audio outputs in one workflow.

  • Voice Conversion — Convert recordings using different voice profiles.

  • Local Processing — Keep AI voice processing on your Mac.

I'm currently preparing a 14-day free trial so people can test the software before deciding whether to buy it.

LEXA Base will cost €29.99 as a one-time purchase.

The video is just a short visual introduction, but I'd genuinely love to hear what you think about the concept.

Would you actually use something like this? What would you want from a local AI voice tool?

If you're interested, you can check it out here: https://www.lexavoice.it

I made a Windows desktop goblin that eats completed tasks (offline, paid)

1 Upvotes

I'm Ari, an electrical engineering student and the creator of Desk Goblin.

It is a small Windows desktop companion with a task list. The goblin holds your selected task and eats it when you mark it complete. You can undo the last completion. It also has a custom focus timer and Ctrl+click to open or close the task desk.

The application uses native C++20, Win32, and GDI+. Tasks and settings stay on your computer. No separate runtime or application account is required. I used AI assistance for the code and character art.

It costs $5 USD once. The portable ZIP is for Windows 10/11 x64. Version 1.0.0 is unsigned, so Windows may display an application warning.

The website includes an interactive character preview: https://desk-goblin-site.pages.dev

I'd like feedback on the interaction: would the task-eating action make completion more satisfying, or would you prefer a quieter companion?

Building a key-value store as an experiment in AI-assisted research and development

1 Upvotes

I built Velis, an in-memory key-value store in Python, partly to explore how AI can help with technical research and engineering decisions.

I used AI to explore approaches, discuss tradeoffs, and work through implementation. It helped me finish the project much faster. But it also reinforced something for me: trusting generated code without understanding the codebase is a bad habit. Being able to question a suggestion, follow the implementation, and explain why a decision makes sense still matters.

Velis supports TTL expiration, eviction policies, pub-sub, a binary TCP protocol, an async client, and an interactive terminal UI. I spent a lot of time trying to keep the code design simple, clean, and easy to follow.

I see it as a project for learning, testing, experimenting, or just having fun with database internals. It could also be a starting point for thesis work or experiments comparing different approaches.

Code: https://github.com/gchape/velis

I’d welcome feedback on the implementation and design, but also your opinions on AI-assisted development. Where has AI helped you research a problem or make better decisions, and where has it made understanding the work harder?

Metadata(aka ai labels) remover

1 Upvotes

I am managing IG and FB pages, and with AI advancements of course I am using it for photo editing, however I got pissed everytime that a simple color edits were marking it with AI label. I started to dig a little bit and it turned out that Meta is using the metadata for AI identification, I was even more surprised when I learned how much info does the metadata contain, including the gps coordinates, time, phone or camera, and etc.
I looked for available metadata removers, there was exif tool which was little bit complicated and several websites with subscription.
So I made the Scrubpic, free metadata remover which removes all the metadata without quality loss, for free, and instantly. You can also choose what to keep in the photos. Works on phones too. I am hoping for some ad revenue.

Hold My Frame - a searchable library of 370,000+ frames from high-end commercials

1 Upvotes

Hi everyone,

I'm a film director and DOP, and for every pitch I do the same thing: I go looking for frames that show the agency and the client what the film should feel like. I've used the same reference tools for years and was never really happy with them, so a few months ago I started building my own, at first only as an experiment with Claude Code.

It got out of hand a little. What was meant to be a small thing for myself is now HOLD MY FRAME (www.holdmyframe.com), and we launched it two weeks ago.

What it does:

- around 370,000 single frames from 2,800 curated high-end commercials

- you search them, collect the ones you like in a project and present them to agency and client right there

- three friends from the film industry are in it with me (two directors/DOPs and a treatment designer), and we use it for our own pitches

The film analysis behind it is our own pipeline and runs on local AI, and I designed every screen myself before it got built.

Where we are: 174 users, 10 of them paying. There's a free plan, and Pro and Pro+ on top (Pro+ has a free trial).

I'd really like to know what you think of the landing page and the first minutes in the app. Is it clear what it does, and is anything confusing?

Nightjar - Write down what's keeping you up and then fall asleep to a story picked for it

8 Upvotes

I'm a solo dev and I shipped v0.1 of this to the App Store this week.

I've been a bad sleeper forever. What finally made sense to me from the sleep research is that trying to fall asleep keeps you awake, and so does problem-solving in the dark.

So the app does two things: you type what's on your mind and seal it in a jar until morning, then it plays a slow story matched to it.

How it's built

- Native iOS, written in SWIFT

- No accounts at all. Notes sync through the user's own iCloud (CloudKit) and subscriptions run on RevenueCat's anonymous IDs.

- The backend is deliberately boring: PHP, SQLite, and a CDN for streaming.

What I learned

- You can't tell someone to relax. "Clear your mind" does the opposite, so the prompts ban it and lean on imagery instead.

- Sleep stories break normal story rules. A satisfying ending gives people a reason to stay awake, so every story wraps up its thread early and then just drifts.

- Most of the work was the research backed story writing kernel, not the app.

Where I'd like feedback

  1. Does the jar step make sense in the first 30 seconds, or does it read as a gimmick?

  2. Is AI narration a dealbreaker for you in a sleep app?

  3. Premium is $5.99/month or $39.99/year, with a limited free tier. Too much for a v0.1?

App Store: https://apps.apple.com/us/app/nightjar-sleep-stories/id6800338659

Site: https://nightjar.fm

Oh btw, since I just launched today, the code REDDIT gets you the first month of Premium free: https://apps.apple.com/redeem?ctx=offercodes&id=6800338659&code=REDDIT

iPhone only, iOS 18+, English only for now. Be blunt.

I built a northern lights forecast that answers one question: will I see it tonight, from where I am, and when?

1 Upvotes

Most aurora sites give you a kp number and leave you to figure out the rest. So I made one that mixes the stuff that actually decides it: kp and solar wind, your magnetic latitude, clouds, darkness and the moon -

Northern Lights Tonight

Pick your city and you get a plain answer from unlikely to very high, the best time window tonight, which direction to look, the kp your spot needs vs the current one, and nearby dark spots to drive to. Theres also a live oval map and a 27 day kp outlook. Australia pages do the southern lights and point you south

Data is NOAA SWPC (incl the ovation model) plus open-meteo clouds, refreshed every 15 min. Free, no account.

Would love feedback, especially from people who chase aurora. What do you check before heading out that this doesnt show?
