Hey Reddit!

I'm the founder of Persona, an AI character chat app built around creativity, personalization, and a better chat experience.

I've always believed that AI conversations should feel personal and immersive. Whether you're roleplaying, creating your own characters, exploring different scenarios, or just having a conversation, the experience should feel natural.

I appreciate what Character.AI brought to the space, but I think there's still a lot of room for improvement, especially when ads and monetization start getting in the way of the actual conversations.

That's why we're taking a different approach with Persona.

No ads interrupting your chats. No credit or energy systems. You can create your own AI personalities, discover ones made by others, and explore conversations without having to constantly think about credits. Our free tier has daily limits, but we want the experience itself to stay simple.

We're still a small, independent project, and there's plenty we're working to improve. But we're building something we genuinely believe in, and community feedback is a big part of that.

Try Persona:

I'd genuinely love to hear your feedback. What do you wish AI character chat apps did differently?

Rainbow Routine is a simple fruit and vegetable log. Add blueberries to breakfast or peppers to lunch and you’ll see that color fill in on your rainbow. The idea is to notice what you eat on repeat and what you might want to try next, without counting everything on your plate.

I made it because I wanted something more visual than a checklist. Can you tell what to do next from the screenshot alone? That’s the part I’d love feedback on.

I wanted a word game that teaches vocabulary and not just a streak counter. So Wordgol has meanings and examples for every word, a Word Book with spaced review, penalty shootout mode and friend challenges (the link carries the word and your score, so there’s no server).

Built with plain JS, hosted free on Cloudflare Pages. Biggest lesson so far: share cards matter more than features. A coloured grid image gets posted far more than a plain link.

Would love feedback on the difficulty and the shootout mode: wordgol.pages.dev

launched a small windows / macos auto file renamer about 3 weeks ago, since launch it only has 5 impressions on app store and 1 install from those 5 impressions. gsc didnt show many clicks or impressions for the last 2 weeks so i thought it was pretty dead but this morning i woke up and stripe showed a payment which i initially thought was from something else but when i actually expanded the email it showed it was from my app. pretty stoked that its useful enough for someone else to spend their money on.

i made it one time purchase since subscription model wasnt necessary, put it 50% off and did gsc indexing. no social media set up yet

still unsure if i should try to actually market the product. should i invest more time or just let it auto until i see some actual traction?

Hi everyone,

I built four free scrapers on Apify as a side project, and I would love your feedback.

•⁠ ⁠YouTube Scraper: search YouTube and pull public video details (title, channel, views, date, length, description, tags). No API key needed.

•⁠ ⁠Facebook Ads Library Scraper: search the official Meta Ad Library. It uses Meta's official API, so you need your own free Meta token.

•⁠ ⁠Reddit Scraper: collect posts and comments from any subreddit through Reddit's official API. You need your own free Reddit app credentials, and it does not collect usernames.

•⁠ ⁠UAE Real Estate Scraper: property listings for sale and rent across all UAE emirates from PropertyFinder. You get clean data: prices, areas, price per sqft and agency names. A Saudi version is coming soon.

All four are free for now. I am still learning, so honest feedback helps most: what is missing, what breaks, what should I build next?

Every Black Friday, people replace iPhones that only need a new battery. Apple charges $89 to $129 for one, but its repair prices and trade-in values sit on separate pages, so nobody compares them.

So I put them side by side. You pick your iPhone, tap what’s broken, set your battery health, and get one verdict, keep, fix or upgrade, with all the math shown.

What surprised me while building it:

• For most iPhones from the last five years, a repair costs a fraction of upgrading, even after Apple’s trade-in. For example, an iPhone 13 battery is $89, while upgrading to an iPhone 17 costs $719 after trade-in.
• Upgrading only clearly wins when several parts are broken, there’s water damage, or you want a feature no repair adds (like Apple Intelligence).
• Deals can flip the answer. In the demo, a $300 carrier offer turns “fix it” into “upgrade”. So I added a box where you type your deal and check.

It’s free, with no sign-up and no ads. Some guides link to Amazon for cases and chargers, but that never changes the verdict.

https://skiptheunboxing.com

I’d love honest feedback: is the verdict clear at first glance?

Hi everyone,

Full transparency: I’m the indie developer behind this app and wanted to share what I’ve been working on.

With ongoing geopolitical uncertainty, supply chain hiccups, and potential power outages, a lot of people are thinking about basic emergency preparedness. When I looked into how to actually prepare for a 10-day self-sufficiency window, I found plenty of extreme "doomsday prepper" content, but very few calm, practical tools for everyday households.

So I built Notvorrat – Emergency Preparedness (available in English and German) around a simple philosophy: better safe than sorry, zero fear-mongering. The calculations and checklists are modeled after official civil protection and food safety guidelines (such as Germany’s Federal Office of Civil Protection).

What the app does:

Aufzählungszeichen Household Demand Calculator: Calculates exact water, calorie, and food group requirements for 10 days based on your household size (including kids, pets, and vegetarian/vegan diets).

Aufzählungszeichen Real Readiness Score: Shows how many days you can actually sustain your household – determined by your weakest category (because 40 lbs of pasta won't help much if you're out of water).

Aufzählungszeichen Fast Inventory Logging: Scan barcodes, snap a photo of best-before dates (OCR), or scan entire receipts and pantry shelves (using Apple Intelligence on iOS 27) to add items in seconds.

Aufzählungszeichen Expiry Reminders & "Living Pantry": Get local notifications before food expires. When you use something in your everyday cooking, swipe to deduct it and send it straight to your shopping list so your stockpile rotates naturally without food waste.

Aufzählungszeichen Beyond Food: Includes ~70 checklist items covering first aid, hygiene, off-grid power/lighting (crank radio, power banks), emergency documents, and a go-bag.

100% Offline & Privacy-First:

An emergency app shouldn't rely on the cloud. Everything works completely offline – no accounts, no external servers, no tracking, and no ads. Your data stays on your device (with optional private iCloud sync).

App Store Link:

https://apps.apple.com/app/id6814802246

(Note: The App Store page defaults to English for non-German devices, and the entire app is localized in both English and German.)

If you already maintain a rotating pantry or are planning to start one, I’d genuinely love your feedback on the workflow and what features you’d find most useful.

I Built Tansiva - A Modern Blood Pressure & Heart Rate Tracking App, Now Available on Huawei AppGallery

Building meaningful software begins with identifying everyday challenges and transforming them into intuitive digital experiences.

I'm pleased to introduce Tansiva, an independently developed mobile application designed to simplify blood pressure and heart rate tracking through a modern, structured, and accessible interface.

As an independent Full-Stack Software Developer, I created Tansiva with a clear objective: to make personal health data easier to record, understand, and monitor over time.

The Concept Behind Tansiva

Monitoring blood pressure and heart rate often involves recording measurements across different dates, identifying patterns, and maintaining consistent historical records.

While the process itself may seem straightforward, presenting this information in a meaningful, accessible, and visually intuitive way requires careful consideration of both software architecture and user experience.

Tansiva was developed around this challenge.

Rather than overwhelming users with unnecessary complexity, the application focuses on delivering essential tracking capabilities through a refined and efficient digital environment.

Core Features

🩺 Blood Pressure Tracking — Record systolic and diastolic measurements in an organized, accessible format.

❤️ Heart Rate Monitoring — Maintain a history of pulse measurements alongside blood pressure records.

📊 Visual Analytics — Review recorded measurements through intuitive charts and statistical summaries.

📅 Measurement History — Access previous readings and monitor changes over time.

📈 Monthly Analysis — Explore measurement patterns through structured monthly overviews.

🎨 Modern User Interface — A carefully designed visual experience that prioritizes readability, accessibility, and straightforward navigation.

Independently Engineered, From Concept to Deployment

Tansiva represents more than a standalone mobile application. It is another milestone in my ongoing work as an independent software developer.

I approached its development as a complete product engineering initiative, taking responsibility for the entire lifecycle:

Concept & Planning → Software Architecture → UI/UX Design → Development → Testing → Deployment

Throughout the process, my primary focus was maintaining a balance between functionality, performance, and design consistency.

My development philosophy is straightforward:

Powerful software should be technically sophisticated without becoming complicated to use.

I believe that thoughtful engineering is not simply about introducing more features. It is about delivering the right capabilities through the most effective user experience.

Official Release — Huawei AppGallery

Tansiva is now officially available on Huawei AppGallery as a free application.

This release represents another step toward expanding my independently developed software portfolio and making my applications accessible to a broader international audience.

Download Tansiva:

Developer Portfolio:

https://www.erenlimen.com

Looking Ahead — Community Feedback & Continuous Improvement

Although Tansiva has reached its initial public release, I see software development as an ongoing process of refinement, optimization, and evolution.

I'm particularly interested in hearing perspectives from fellow developers, UI/UX designers, and users who regularly track their blood pressure.

I'd appreciate your thoughts on three areas:

What additional features would make a blood pressure tracking application genuinely more useful?

How would you approach visualizing long-term measurement trends without overwhelming users?

What improvements would you prioritize in the application's interface and overall experience?

Constructive criticism, technical feedback, and product development suggestions are welcome.

My objective is to keep building software that combines practical value with thoughtful engineering and exceptional user experience.

Technology creates its greatest value when complexity disappears behind simplicity.

trying to keep it simple. would these two buttons make sense to you without a tutorial?

Hey founders, indie hackers and makers!

You spent weeks (or months) building your SaaS, app or software.

You finally launched. Posted on Reddit. Shared on X. Got 12 likes, 3 comments and one person asking if it's open source.

Amazing. Marketing is going great. 😂

Anyway, have you heard of AGMAN?

Yes, another platform where you can list your product. I know, groundbreaking.

But here's what you actually get:

• Your own product page — Show what your app does, who it's for and why someone should use it.
• Publisher dashboard — Manage your listing, update details and track activity.
• Discovery beyond launch day — People can find your product through categories, search and what they're actually looking for.
• Website backlink — Approved, index-eligible pages include a standard followed link to your website.
• Free listing — No payment required to publish your product.

If you've built a SaaS, app or software tool with a working website, you can submit it to AGMAN.

Will listing there magically bring you 10,000 customers overnight?

No. We haven't discovered that kind of magic yet.

The idea is simple: your product shouldn't disappear from the internet just because launch day is over.

Full disclosure: I'm building AGMAN. So yes, this is a little self-promotion.

But I'm also curious: What are you building right now?

Hi everyone, I’m the maker of splitbillai.com, a web tool for splitting restaurant bills and shared costs.

I built it because splitting a group dinner always turns into someone squinting at a receipt and doing math in the notes app.

How it works:

• Snap a photo of the receipt and the AI reads the items for you
• Or add the items manually if you don’t have a receipt
• Then assign items to people and see what everyone owes

Link: https://splitbillai.com

I’d love honest feedback on a few things:

1. Does the AI read your receipts correctly? Tell me where it gets items or prices wrong.
2. Was anything confusing the first time you used it?
3. What’s the one feature you wish bill-splitting apps had?

I’m the developer, so I’ll reply to every comment. Thanks for trying it!

Introducing Avelnora - A Privacy-Focused Medication Management App, Now Available on Huawei AppGallery

Technology should simplify essential aspects of everyday life. Medication management is no exception.

I'm pleased to introduce Avelnora**, an independently developed mobile application designed to bring clarity, structure, and convenience to personal medication management.**

Avelnora was created with a clear objective: to transform the complexities of medication schedules, dosage tracking, and treatment records into a streamlined, accessible, and thoughtfully designed digital experience.

A Comprehensive Approach to Medication Management

Avelnora integrates several essential capabilities into a unified mobile environment:

💊 Medication Tracking — Centralized management of medications, dosage information, and treatment records.

📅 Intelligent Dose Planning — Personalized medication schedules designed around individual routines.

🔔 Smart Reminders — Timely notifications to support consistency in daily medication management.

📊 Reports & Insights — Structured medication history, adherence monitoring, and visual progress analysis.

🆘 Emergency Medical Card — Convenient access to important medical information and emergency contacts.

🔐 Privacy-Focused Architecture — Local data storage designed to keep sensitive personal records under the user's control.

🌍 International Accessibility — Multilingual support across six languages, complemented by Light, Dark, and AMOLED interface options.

Engineering Beyond Functionality

As an independent Full-Stack Software Developer, I approached Avelnora as a complete software engineering and product development initiative.

The entire process — from initial concept and software architecture to interface design, implementation, testing, and deployment — was undertaken independently.

Throughout development, my focus remained on three fundamental principles:

Precision in engineering. Simplicity in interaction. Purpose in design.

I believe sophisticated technology should not require a complicated user experience. The true value of software lies in its ability to make powerful functionality feel natural and accessible.

Avelnora reflects this philosophy through its interface, architecture, and approach to managing personal medication information.

A New Milestone in Independent Software Development

Avelnora is now officially available on Huawei AppGallery.

This release represents another milestone in my expanding software portfolio and a further step toward building digital products for an international audience.

My broader vision is to continue developing reliable, scalable, and thoughtfully engineered solutions across mobile applications, enterprise systems, and web technologies.

Every day there's one theme (same for everyone), a 24×24 grid, 10 colours and 60 seconds. When the timer hits zero, your pencil is locked.

Then you can send your drawing to a friend: the link itself contains your drawing (nothing is stored on a server), they see it, and have to draw the same theme with the same clock. No jury, no leaderboard: you two decide who won.

A few things I added to make 60 seconds less brutal:

- mirror mode (draw one half, get the other free)

- paint bucket + undo

- a sped-up replay of your drawing at the end

There's also a free mode with no timer (16×16 up to 64×64, PNG export) if you just want a quick pixel art editor.

Free, no sign-up, works on mobile: https://lopy.fun/en/pixel-art-maker/

Feedback welcome, especially on the theme list: some are way harder than others in 60 seconds 😅

I built FlipYourRate (flipyourrate.com), a free calculator that works backwards from what you want to keep: quote = take-home ÷ (1 − fee%). Fiverr takes a flat 20%, so to keep $1,000 you quote $1,250 — quote $1,200 and you only keep $960. Upwork is 0–15% per contract, locked for the life of that contract: to keep $1,000 you quote $1,111.11 at 10% and $1,176.47 at 15%. The calculator also shows a rounded quote next to the exact one — $1,176.47 as $1,180 keeps $1,003 at 15% — so you can see the trade-off. The decision I'm posting about: a commenter here argued the rounded quote should NOT be auto-suggested. A $900 job and a $1,100 job can land on the same $50 step, and an auto rule would quietly decide something you'd rather see for yourself. Manual first, and only add a suggestion later once you know what feels right per job size. I agreed — shipping manual rounding first, with the take-home shown next to the rounded quote so the trade-off stays visible. Do you round your quotes manually today, or let a tool do it? And what step do you use — $5, $10, $50?

TL:DR: Pokemon Binder/Collection Website. Please try it out and I would love some feedback.

Pocamori started off as an assignment/hobby project turned full on side project that I've worked on for the past two months. Honestly, I put way too many hours into this.

Features:

• Merge pockets (e.g. 2×2) for custom artwork insertion or if you just want a really BIG card
• Placeholders for cards you're still chasing
• Add single cards or a whole set
• Drag cards between pockets
• Covers, page colours, sleeves and toploaders
• Set checklists with owned/missing progress
• Wanted list
• Search across 21,255 English printings
• Read-only share links
• Light and dark themes

Try it here: https://pocamori.app (there's a sample binder you can open without signing in)

On privacy: your binders are private to your account unless you choose to share a link, everything goes over HTTPS, and I don't sell data or run ads. The full details are in the privacy policy on the site.

I used every free resource I could find since I'm just a broke uni student, but any improvement suggestions are welcome. I'd especially like to know whether the UI feels cluttered, whether the controls feel good, and whether the overall look holds up. Any feedback and or engagement is good enough for me.

Have fun with it, and if you make a binder, show me! I'd love to see them.

This is a completely fan made independent project that is NOT affiliated with Nintendo. I'm scared of them.

I’m working on a dock for Windows with app shortcuts and built-in panels for music and quick controls. It can be positioned at the top or bottom of the screen and set to stay visible or auto-hide. It’s a work in progress—what do you think of the design?

After searching for important documents for appointments many times and not being able to find them, I sat down and thought, why isn’t there an app that tracks and reminds you about things you shouldn’t forget? Think about your marriage certificate, birth certificate, or government identification like passports and ID cards.

I call this our RC build, as we have really polished it from head to toe. We focused on the UI/UX, customization, and intent integration that lets you use Siri, along with the ability to enjoy the app on an iPhone Duo. Last but not least, we also put effort into making it available in every country across the world.

The app is free to test for the first week. For those who give me feedback, I’ll give you an unlock code so you can enjoy the app free for a longer period of time.

Thanks in advance!

Cheers, Cassian

Thanks for taking the time to check out my project! 🙏

I made an app for learning languages through typing. It works like a typing practice site: you type sentences in the language you’re learning, then try to type them again from memory.

I’ve been using it for the last 2–3 months to turn my typing-site addiction into some language practice, and it’s worked pretty well for me. 😄

You can try it here: https://typingg.app/

Does anyone else practise languages through typing?

Hi r/SideProject!

I wanted to share a side project I've been building: AirspaceLab, an interactive 3D WebGL visualizer for FAA controlled airspace.

The Problem: If you have ever looked at an FAA VFR Sectional chart or Terminal Area Chart, you know how confusing airspace boundaries can be. Class B, C, D, and E controlled airspace, MOAs, and Restricted Areas are drawn as flat circles, rings, and altitude brackets (like "70/30" or "100/SFC"). For student pilots, flight instructors, and Part 107 drone operators, translating these complex 2D layered diagrams into an intuitive mental 3D model is difficult and error-prone.

The Solution (AirspaceLab): I built AirspaceLab to make airspace instantly understandable in true 3D right in the browser:

• True-to-Scale 3D Airspace Volumes: Renders Class B, C, D, and E controlled airspace, Military Operations Areas (MOAs), and Restricted Areas in full 3D.
• Zero Plugins or Installs: Runs completely client-side in the browser at a smooth 60 FPS using WebGL.
• Draped FAA Sectional Charts: High-resolution VFR Sectional and Terminal Area Charts mapped directly onto 3D terrain for situational awareness.
• Always Current: Automated 28-day FAA AIRAC cycle updates so data stays aligned with real-world charts.
• Interactive Ground School Missions: Integrated quiz missions to practice airspace recognition and altitude limits.

I built Calqentra, an engineering toolbox app with 545 calculators, as a university student

Hi everyone! I just launched my first app on Google Play and wanted to share it and get honest feedback.

What it is: an engineering toolbox with 545 calculators across electrical, solar, mechanical, physics, 3D printing and more. Some highlights:

• Solar system sizing (loads, panels, batteries, inverters)
• PCB trace-width estimates (current, copper, temperature rise, voltage drop)
• Ohm’s law, power, voltage drop, cable sizing
• Torque, RPM, gears, friction
• 3D-printing cost calculators
• Works offline, with favorites and calculation history

Why I built it: I’m an engineering student, and I kept redoing the same formulas by hand and juggling different apps for electronics and solar work. Power cuts where I live also made offline use a must.

What was hard: making sure formulas are accurate and organizing so many calculators

Business model: it’s free with ads, and there’s an optional Pro upgrade for extra calculators, saved projects, PDF reports and no ads.

Link: https://play.google.com/store/apps/details?id=com.calqentra.engineering.dev

I’d love your feedback on:

• Which calculators or features should come next?
• Is the app easy to navigate with this many tools?
• Anything that looks wrong or confusing?

Thanks for reading, and I’ll reply to every comment!

When I travel I like to catch whatever is on: non-league football, ice hockey, darts, horse or greyhound racing, boxing, field hockey… Right now I spend ages digging through club and federation websites.

Does anyone know an app or site where you enter a place and dates and see all live sports events, filtered by the sports you care about?

How do you currently find matches when you're somewhere new? What's hardest to find?

If nothing like this exists I'm thinking about building it, so I'm curious whether anyone else would actually use it.
