### 5/5 — Best App Ever

*2026-10-29*

This is my first paid app on the App Store. Long Before Calculator was available for iPad this was the solution. Really appreciate the developer for keeping this up to date, and delivering timely updates and implementing quality of life changes over the last few years. This is a must have and I recommend everyone to use this. It has completely replaced apple calculator for me.

very useful

### 5/5 — Very Good!

*2026-03-14*

I was looking for an upgrade to the native Apple calculator that would provide a history of calculations (a tape). Solves does this well and works on iPhone, iPad and Mac. I almost stopped using it because of no clear or clear all key, but the developer built in the clear function as a swipe up. You can also turn the clear key on in settings if you want a physical key. Now it’s exactly the calculator I wanted!
