Description by Andrii Bashta Written by the developer, not by AppBrain. Click to read.

Sigmakey is a math keyboard for people who need to type actual math, anywhere you can type at all. Fractions, exponents, roots, Greek letters, and matrices sit one tap away, and the cursor moves right into a numerator or an exponent, so scientific notation looks the way it should.

- A full math keyboard layout that works in any app with a text field
- A two-dimensional field with a cursor that steps into fractions and powers
- Type LaTeX, plain Unicode, or a rendered image, whichever the app expects
- Everything typeset on device, with no network
- Search for a symbol, or grab a recent or a favorite

Drop an equation into a note, a message, or a homework app without hunting through menus.
