About this app

Keys are divided into different key-groups. The Criteri-R key-group targets the Criteri-R app. The User key-group allows users to define their desired key texts like macros. Alphabets and General punctuations and symbols are added for normal inputs.

Besides the common math input keys, on the keyboard there are a number of mutable keys whose contents can be changed to map to any keys in the selected key-group. Users can define as many keys as they need in the User key-group. In this way, Math Keyboard can be used to serve Criteri-R as well as other apps, e.g. Excel, WolframAlpha, etc.

Superscript and subscript counterparts, if available for a character, can be attained through the Shift key.

Through in-app purchase, more characters become available: arithmetical, Greek, arrows, brackets, mathematical, accounting, calculus, logical, set theory and multi-line characters. They will all be displayed on your device before you agree the purchase.

Remember to enable and select Math Keyboard in System Settings after installing.

Ratings and reviews

It is actually a fantastic app, which lets me type things like abs(), sqrt(), atan(), x^(-5), and X₁ + X₂. The only bad thing is that the default alphabet layout is horrible; you have to choose QWERTY in the app. I can say this app wasn’t made for texting—you have to change it while writing, or you are forced to use caps lock for the rest of the time. But I don’t think anyone cares about the tabs; this is for solving or writing questions, and the app is doing its job, so it is perfect.

It is kinda wierd that this app has 100k+ downloads and 0 revievs. To make it work you have to enable access to your data, and i don't know what to think about it.

Really difficult to use, most of the symbols needed are locked behind a pay wall, forcing me to switch between the Samsung keyboard and the maths keyboard every 10 seconds just for it to not have the symbols needed. Caused more of a faff, then help, easier to copy the symbols onto your keyboard and paste when needed, at least that's all in one spot. When using at a college level, the price just isn't worth it. Thanks xx

Alphabets layout may be qwerty.
