Ratings and reviews

My favorite calculator so far. I've tried many others including CAS emulators. This one has all the features I need: history, copy/paste, pretty print, solve, variables. Edit: it's still a good app, but it has lots of bugs. The most annoying appeared a couple months ago. If you tap the backspace key, it sticks, and deletes everything.

The backspace button deletes everything before the cursor unless tapped again. It's like an on-off toggle instead of just a one character backspace. It makes it super frustrating to correct a mistake, because if you don't time it right, you delete way more than you expected. (Emailed details, it's great otherwise!)

When switching apps back and forth, this app ask whether I want to save my expression or not, it's very annoying because it keep asking every time, otherwise the app is fast and even shows the graph of my expression.
