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.

Great app for maths/physics students It also consists of an option to make your own keys which helps in adding more mathematical symbols to your keyboard 🫡

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

The concept of this keyboard is ok but in practical this type of keyboard is not useful for Android users in any way. Maybe good for those who have a hobby of experimenting with different keyboards but other than that I don't see what I can do with it.

Doesn't actually type math symbols. Just shows them and outputs the English corresponding definition. (Instead of the Greek symbol, it says, "pi.") Also, very difficult to switch between math keyboard and English.

Unable to purchase extra characters. It is showing "The item that you were attempting to purchase could not be found." I need the greek characters and the calculus symbols.

Plz skip it, if you download it you will asked to enable it and then everything that you type will be memorized by it(passwords etc) so it can hurts you
