App Description

The Chemistry Keyboard is a specialized Keyboard Extension for anyone who needs to enter chemical formulae. Ever need to input Hg²⁺+2 I⁻ on your phone and can't figure out how to get those nice superscript or subscript 2s. Or proper arrow glyphs?

Well, your wait is over.

Quickly generate
superscripts: ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁽ ⁾ ⁺ ⁻,
subscripts: ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₍ ₎ ₊ ₋,
and arrows.

lowercase Greek characters available in landscape mode.
and other chemistry related Unicode characters.

The app itself demonstrates the keyboard's use by allowing text entry and looking up data from Wikipedia.

Unlike many keyboard extensions, this keyboard does not require network access. It's entirely self contained.
