## Most critical reviews (9 lowest-rated)

### 1/5 — Absolute waste of money

*2022-01-30*

Only basic number and symbol set. Doesn’t work on latest iOS

Crashes display, obliterates working window. Money back please

### 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.

### 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.

### 3/5 — not as ideal

*2021-09-06*

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

### 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.

### 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.

### 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.
