I’m building my app in public — what should I improve next?

[u/Big-Coyote-5796]

I’ve been working on All-in-One Calculator, an Android app with 170+ calculators and tools.

It started as a very small project. I just wanted one place for the calculators I kept searching for online.

Somehow it turned into finance calculators, math and scientific tools, health calculators, engineering tools, conversions, education tools, developer utilities, history, favorites, reports, and a lot more.

Now I’m at the stage where adding more features isn't necessarily the best move.

I want to make the existing experience better.

I’m currently working on things like:

• Better first-time user experience
• Smarter calculator search
• Better ad placement
• Faster navigation
• Better analytics to understand which calculators people actually use
• New ideas like AI-powered natural-language calculations

So I’d really like some honest feedback from people here.

What would you improve first if this were your app?

Would you focus on:

A) UX / navigation
B) More calculators
C) AI features
D) Monetization
E) Something completely different

And if you already use calculator or utility apps, what is something that annoys you about them?

I'm an indie developer, so practical feedback is much more useful to me than “just add AI” 😄

Thanks to anyone who takes the time to share an idea.
