Doesn’t work on latest iOS Crashes display, obliterates working window. Money back please ### 3/5 — not as ideal *2021-09-06* it doesn’t have the vast math symbols i’m looking for, just some simple ones ### 1/5 — Doesn’t have pie symbol and won’t switch between screens *2018-08-28* I can’t switch to other symbols that are supposedly with this app. Also I do not see a pie symbol. ### 4/5 — Good funcitons but paid app with large ads *2018-02-18* 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. ### 3/5 — Worked on my iPhone 6S+, but not on the X *2017-11-13* 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. ### 2/5 — Missing parentheses *2015-01-25* 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 ### 2/5 — Ads on a paid app *2015-01-03* I just purchased this keyboard and the first thing I see when I launched the main app is a pop-up ad. Pop-up ads have no place in a paid app like this. Bad choice by the developer. ### 4/5 — Finally! I can text about math homework! *2014-11-18* 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. ### 4/5 — Very well done *2014-10-13* 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. ## Frequently asked questions about Calculator Keyboard ### What is Calculator Keyboard?
