Better than stock

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.
Testing the five star rating.

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.

Thanks for your advice！"copy a number or equation, instead of the “copied to clipboard” being in English, it’s in a different language. "I made a mistake here，it's Chinese right now，i will fix it using English
Seamless and efficient

The fraction mode is incredibly well done. It saves me so much time because I don’t have to toggle between fractions and decimals anymore. It just works seamlessly. Best calculator app by far!
