Doesn't allow multiple operations to be entered at the same time, so the user has to sort out Order of Operations and enter them manually in proper order. So 10+10+10*100 ends up being 3000 (incorrect) instead of 1020 (correct use of Order of Operations)... On a positive note, for TWO numbers and ONE operation, it does fine. Overall, I would look for a different calculator. Google's "default" calculator has no ads, is lightweight, and can properly process multiple operations.

This calculator is good for very basic math and that's what it is advertised as so I'm fine with that. Unfortunately, I'm looking for something more beefy that can deal with physics equations, but as I said, this app is up-front about it being just a basic calculator. Ads are annoying but you can disable them for a fee which is fair.

Oh look!!... finally, a calculator with a % key... Holy s**t!! - would give 5⭐ but #1. Has too many themes... dude, it's a calculator, not a My Little Pony sticker book and #2. It unnecessarily converts the %age to a decimal number before the operation is complete, just adds an unnecessary step. Fix these two things and you'll get 5⭐ from me.
