Comments on Mathematical keyboard B for Android

★★★★★ ho ho · Jul 21, 2019
This is very useful as you can enter numbers, symbols and Greek letters without switching. I'm glad I didn't include it as I typed in the alphabet as I wrote sentences on other familiar keyboards. Anyway, I'm glad it is not necessary to switch otherwise.
★★★★☆ Marco Roa · Feb 8, 2021

Description by hosinoatusi Written by the developer, not by AppBrain. Click to read.
This is a soft keyboard that is convenient for writing math problems, expressions, etc.
Numbers, symbols and Greek letters can be entered without switching the keyboard or converting.
You can enter numbers 0 through 9 and "∫∬!?√#%$\°'"^:;∠⊥△∴∞&|_+±-~*×/÷=≠≒≡≧({[)}].," for mathematical symbols.
If you press the key of the symbol continuously, it switches to a different symbol.
When Greek lowercase letters "α, β, θ, μ, π, σ, ω" are pushed continuously, it switches to uppercase letters "Α, Β, Θ, Μ, Π, Σ, Ω".
Please enter the alphabet with another keyboard.
