Calculator Keyboard - Easy to Use Math Symbols

it doesn’t have the vast math symbols i’m looking for, just some simple ones

I can’t switch to other symbols that are supposedly with this app. Also I do not see a pie symbol.

Loses a star automatically for the type of ads. I probably would have ignored this minor inconvenience since it doesn’t affect actual keyboard use, but the first time I opened the app an ad froze/crashed the app. Second attempt showed a full-screen video ad for some game, with a delayed skip option (not to mention the maliciously placed ‘skip’ trying to bait a mis-click). Otherwise, the actual keyboard’s good. Layout is so-so with multiple pages to scroll through, but I’m sure that’s for iPhone optimization so can’t fault them there.

App appears to be abandonware. The keyboard worked fine on my iPhone 6S+, but does not work on the new iPhone X. Some parts of the keyboard are hidden behind the app now. I wanted to report a bug, but the app support link in the App Store just goes to a blank web domain/page.

This app would get five stars but it is missing a fundamental symbol in math: parentheses. It has this strange subscript parentheses but it doesn't have any regular parentheses and that is a deal breaker for me since parentheses are in most of the equations I type

This app is fantastic. Best $2 I've spent in a long time. I didn't think there were any out there that actually added a keyboard to the operating system until this. All of the other ones just give you copy and paste methods which are very annoying. Only got 4 stars because it has no dynamic fraction creation, so you can only use the few standard ones like ¼,⅚, ⅖, etc. This was expected though. Overall great app. I highly recommend it to students or people who just need to communicate about math.

Love it! Excellent UI complete with arrow keys. But for a paid app, the ads need to be removed. Also, it doesn't have the delta (Δ) symbol.
