One thing I’ve learned from building a product for myself is that feature creep does not always feel like feature creep.

Every new feature can solve a real problem, which makes it easy to justify adding it. The harder question is whether all those useful features still form one coherent product.

I’ve been writing code for more than 15 years, and throughout that time I created small tools to make my own workflow easier. About three years ago, I started building Arezgit. It was originally a visual Git client, but I gradually integrated tools I was already using separately: database management, test-data generation, API requests, a Pomodoro timer, a task board, and more.

My answer to the scope problem, at least for now, has been to keep Git and the commit workflow as the clear center of the product.

The latest update focuses heavily on that. It can scan files for passwords, API keys, and other secrets locally and without AI, remove code comments in bulk, and optionally review code and generate commit messages using your own Gemini or OpenAI API key. The source code is never sent to Arezgit’s servers.

Most features are free, including visual Git for both public and private repositories. There are paid features, but around 90% of the system is free.

For transparency, I have used AI during development for things such as translations and some front-end work. I am mainly a back-end developer, although I also wrote much of the front end myself. Everything AI-assisted was reviewed several times, and I rewrote anything I did not fully understand or agree with.

This is the biggest project I’ve built, and I’m still improving it constantly.

I would be interested in hearing how other builders think about this: can a product remain coherent while bringing several adjacent tools together, as long as one workflow stays clearly at the center? Or would you split these tools into separate products?

Any honest feedback would help a lot.

After months of building this thing, the first-ever StreakWars game is finally starting.

The rules are borderline stupid:
📸 Everyone joins the same War
⏰ You have to post proof before the clock runs out
💀 Miss once = you’re fucking out
🏆 Last person still alive wins the pot

That’s it.

No XP. No levels. No 45-minute gaming sessions.
We built it because we’re adults with jobs, meetings, kids and approximately 11 minutes of free time…
…but somehow we’ll still spend 45 minutes talking shit in a group chat.

So we thought:

What if the group chat WAS the game?
Something you check for 30 seconds a day, talk an unreasonable amount of shit about, and slowly watch your friends get eliminated because Kevin forgot to take a fucking selfie on Tuesday.
And now we’re actually testing it.

WAR #001 starts soon.

Which is mildly terrifying because this will be the first real StreakWars game ever played.

The rules will probably evolve.
Something will probably break.
Someone is absolutely going to get eliminated in an embarrassingly stupid way.

And one psychopath is going to outlast everybody.

So before we start, Reddit gets to decide something:
What would YOU be most likely to survive?
A) Daily selfie
B) Outfit check
C) Photo of your lunch
D) Couples selfie
E) Something considerably more unhinged — comment it 👇

Also:
How many days do you genuinely think you’d last?
I’m saying 6 before half of Reddit forgets. 😂
If you find StreakWars right now, you’re ridiculously early.

No giant community. No polished corporate launch.
Just War #001 and a bunch of strangers about to find out who has their shit together.

May the least forgetful idiot win. 🫡

App Name: Aion Alarms

What it does: Aion Alarms is a true "set-and-forget" smart alarm clock built for people with dynamic routines, shift workers, and heavy sleepers. Instead of manually toggling alarms every night, Aion seamlessly connects to your Google Calendar to automatically adjust, enable, or skip your alarms based on your real-life schedule.

Key Features:

• 📅 Calendar Sync & Holiday Skip: Link alarms to specific calendar events. Aion will automatically mute the alarm if it detects a "Holiday" or "Vacation" event on your calendar, so you never accidentally wake up early on your days off.
• 🔄 Ultimate Shift Support: Natively set alarms for specific days or alternating weeks or months. Got a crazier rotating schedule (like 4-on/2-off or random hospital rosters)? Just put your shifts in Google Calendar! Aion will read your events and only ring when you actually have to work.
• 🛑 Anti-Procrastination Toolkit: Chronic snoozer? Force yourself out of bed with the Barcode Challenge (scan your toothpaste in the bathroom to stop the alarm), or activate the Discipline Ads Challenge to wake up your brain.
• 🤖 AI Assistant (Beta): Includes an experimental AI Assistant (powered by NotebookLM) specifically trained on Aion's internal rule engine to help you set up and troubleshoot complex alarm schedules.
• 🔒 100% Offline, Private & Reliable: Zero tracking, no accounts, and your calendar data never leaves your device. Built with native Android exact alarm APIs (USE_EXACT_ALARM) so aggressive battery optimization won't silently kill your morning alarm.
• 🌐 Available in 21 languages.

Goal: Launch & Feedback (I'd love to hear your thoughts and suggestions for new features!)

Hi!

I built pawtrck, an iPhone app for dog owners who want their dog’s care records in one place.

It started from a pretty simple problem: dog care is usually scattered across Notes, Reminders, photos, screenshots, fitness apps, and memory. pawtrck brings the main parts together:

• Walks, runs, and bikejoring sessions
• Distance, duration and estimated pawsteps
• Meal, treat, calorie and weight tracking
• Medications, vaccinations, symptoms and vet visits.
• Training plan and progress
• Shareable activity cards after exercise

One thing I’ve heard from dog owners is that dog walks can mess up their own fitness stats because they’re slower and more stop-start than normal workouts. pawtrck keeps the dog’s activitiy separate and dog-specific.

The app is freemium, with Plus ($3.99/mo) for advanced features and a 1 month Free Trial.

I’d really appreciate feedback from iOS users, especially around onboarding, pricing and whether the app feels useful enough to keep using long term.

Hi! I’m the dev behind PostSpark, a tool for creating beautiful image and video mockups of your apps and websites.

I recently launched a new feature: Mockup Animations.

You can now select from 25+ frames & devices, add keyframes on a simple timeline, and export a polished video showcasing your product. It’s built to be a fast, easy alternative to complex motion design tools.

Try it out here: https://postspark.app/templates

I’d love to hear your feedback!

Hey r/windowsapp! I built iBlink, an app for people whose eyes feel dry, tired, or strained after long screen sessions. First built for myself.

It uses your webcam to monitor your blink rate in real time and gives gentle on-screen reminders only when you’re blinking less than usual. We partner with clinics and optometrists across North America who love recommending it to their patients!

Everything happens locally on your PC, no video is recorded, stored, or sent to a server. The webcam frames are analyzed in real time and immediately discarded.

There’s a quick calibration step so it can adapt to your eye shape and lighting, and a 7-day free trial with no credit card required.

Use promo code Reddit33 at checkout for 33% off the lifetime license ($19.99 instead of $29.99)

Indepth walk through on site!

Please let me know if you have any feedback.

I’m working on a product for founders who want to make better decisions before spending time, money, or traffic on the wrong thing.

The problem I’m trying to solve:

A lot of startup decisions are expensive to validate.

Changing pricing can hurt conversion.
Changing copy can confuse users.
Changing onboarding can reduce activation.
Launching a feature can waste weeks.
Running interviews or A/B tests takes time and often requires traffic you may not have yet.

So I’m building Polyhyle: a simulation platform where you can model a product/business scenario and see how different synthetic user segments might react.

Examples:

• simulate a pricing change
• test positioning and landing page copy
• predict objections before launching
• compare feature concepts
• simulate user reactions to a competitor move
• estimate impact on conversion, churn, adoption, or trust

To be clear: I don’t think simulated users replace real customers.

But I do think they can help founders narrow down bad ideas faster, generate better hypotheses, and decide what is actually worth testing.

I’d love feedback from other founders:

What’s one startup decision you wish you could simulate before making it?

I've been building Discovery Companion as a side project and I'm at the stage where feedback from people who know me isn't enough.

It's designed around the work that happens during and after customer discovery: keeping customer context, opportunities, discovery, requirements and the resulting customer-facing documentation in one structured workflow.

https://discoverycompanion.app

Don't worry about being nice. I'd particularly like to know:

• Within 30 seconds, do you understand what it does?
• Who do you think the actual customer is?
• Does the problem feel real or manufactured?
• Does the workflow/product seem useful or overcomplicated?
• What would stop you creating an account?
• Does €24/month feel sensible, too high, too low, or irrelevant because you wouldn't use it anyway?
• What looks amateur, untrustworthy or confusing?

One thing I'd especially like to avoid is explaining the product myself and then hearing that it makes sense. I want to know whether it makes sense without me there.

For context only after you've had a look: the initial audience I have in mind is consultants and solution professionals working around CX, contact centres and CCaaS. I'd be interested to know whether you got anywhere near that from the product itself.

Roast away.

we all something, these days everyone is building something. We've actually been obsessed with creating something. And that's what we're doing.

A few months ago, i built a small app, I started paying more attention to what people were saying about the products we were using. It was surprisingly messy.

One useful comment was on Reddit. Another was buried in an App Store review. Someone mentioned a feature they wanted on X. Then a competitor launched something interesting, and we almost missed it.

The weird part was that all of this information was available. We just didn't have a good way of putting it all together.

At some point, I realized I was spending more time on building in features instead of listening to the customer and understanding it

So we started building something for ourselves. That's how Mindphor started.

It brings customer feedback and competitor activity together and uses AI to find the patterns that are easy to miss when you're checking everything manually. You can use it for your both android and ios apps.

It's still early, and we're learning a lot from putting it in front of other founders.

We're launching it now, so if you're building an app and this sounds like a problem you've run into, I'd genuinely love to hear how you deal with it today.

Here's the link: Mindphor

Hey my names Mike I’m the founder of Smart Post app. It’s a free app I’ve been working on for years to help small business schedule content to social media networks. We recently launched a new feature called Engagement that brings in your accounts most recent posts along with any comments and threads. We have support for Facebook Pages and are working on Instagram now.

We would love any feedback good or bad!

Thank You

Have spent months on Duolingo before moving to another country and realized that while I can say "the horse drinks milk," I have no idea how to ask a landlord about heating. Vocabulary is great, but there were just not any specific goals.

So I created something where you tell me your motivation — job relocation, partner's family, whatever — and we create the lessons tailored to that, rather than anything else. Normal course still exists if you just want to learn language.

Just wondering what you people think in this sub: does goal-oriented approach really work better, or should one start with boring basics first? Cannot make my mind up.

Here are a few things that make HabitSet different:

- Flexible streaks that actually make sense

Track habits weekly or monthly (like 3x/week or 8x/month) without fake daily streak pressure.

- Your history stays intact

Changing a goal won’t automatically destroy your existing streaks and progress.

- No random streak losses

Time zones and DST are handled properly, so your progress stays reliable.

- Reminders that aren’t annoying

They stop once you complete a habit and return only if you undo it.

- Fast home screen widgets

Complete habits instantly without opening the app.

- Fully offline & privacy-first

No account, cloud sync, or data collection. Your data stays on your phone.

There’s also a compact layout for tracking many habits, plus lightweight stats that stay useful without becoming overwhelming.

Every review genuinely helps 🙏

Around 2-3 weeks ago I launched my SaaS, SeoLoupe.

It is a lightweight SEO tool that helps you find and fix SEO issues holding your website back, currently I am at 432 users and 5 paying users.

Essentianly the main purpose is to help your website rank higher on Google search and LLMs.

Since I am always trying my best to improve the product, I am happy to answer any questions or any feedback in the comments.

(here is the product if you want to check it out)

So I built this directory for people to showcase their products. I wanna make it different for builders in a way that their product stays in public for a longer period of time rather than just a launch day. I've always come across this situation where waiting for months for the launch day still gets you ghosted. This is an approach to go beyond that and always have the products in front of the right people.

Also, builders who're truely in for making their product stand out, i've made a builder tier for them that really helps them stand out from the regular products. Pricing honestly feels like a deal.

I've also implemented analytics for people to see how they're doing on the platform.

For normal users to navigate through the platform, I've implemented semantic search. just give it a proper description on the search bar and look at it come up with the best products.

Currently with just a few products covering every category. I'm on a quest to grow this platform more and more.

I'd love for your to be genuinely unhinged on the UI/UX, Navigation, Pricing, Features, Everything.

What it does: Click the Dock icon and a panel pops up holding named "stacks" of your favourite apps, folders, files, and website bookmarks — instant access without cluttering your actual Dock or Desktop.

Some of what's in it:

• Drag and drop to add anything, including URLs straight from your browser
• Password-protect individual stacks (Keychain-backed, auto-lock)
• Global keyboard shortcut to show/hide from anywhere
• Menu bar mode if you'd rather not use the Dock at all
• Multi-select, custom grid sizes, tab colour tinting
• Fully local — no accounts, no tracking, no network access

This is my first shipped Mac app, built from wanting faster access to the stuff I actually use every day. One-time payment 4.99USD or equivalent, no subscription.

App Store: https://apple.co/3Rz9FB6
Website: https://dockstacks.app

Would love any feedback — recent launch, still learning a ton.
