Calculator-Math Toolbox

I’ve tried many calculator apps, but this one stands out for its clean design, smooth performance, and wide range of useful tools. It handles everything from basic calculations to scientific functions, fractions, currency conversion, unit conversion, and even mortgage calculations—all in one place. The interface is intuitive and easy to use, and I especially like the editable calculation process and history feature, which make correcting mistakes and reviewing previous calculations effortless. The app feels fast, reliable, and thoughtfully designed for both everyday users and professionals. If you’re looking for a powerful yet simple calculator app that covers almost every calculation need, this is an excellent choice. Highly recommended!

Having a back button to erase one number instead of starting over is how stock calculator app should be. Stupid thing is you have to write a review and give it 4 stars to be able to use the history feature. Oh well it's what I was looking for so here's my review.

You have to comment and give five stars to use the history function? This seems like it should be a violation of apple’s app policies. Update: so far the app is fine. There is an odd thing where if you go to calculation details then try to copy a number or equation, instead of the “copied to clipboard” being in English, it’s in a different language. I updated my review to a 4, because blocking users from the full app by telling them they have to review it 5 stars seems wrong. You don’t have to rate it 5 stars to access history, it’ll work with any rating.
