### 1/5 — iOS 26 not working

*2026-01-31*

Doesn’t allow you to calculate, you enter one value and are stuck.

**Developer response:** Thanks for your feedback, and sorry for the confusion!

This app works a bit differently — once you enter one value, the other side is calculated automatically, so it might feel like you’re “stuck” at first. But that’s actually how it’s designed 😊

We’ve also updated the app to support iOS 26, and everything should be working as expected now.

We really appreciate your feedback and are already looking into ways to make this clearer and easier to use in future updates.

If you give it another try, we hope it works better for you! 🙏
