Introducing a revolutionary advancement in bringing engaging chemistry education to younger students, underfunded school districts, and curious learners: Tactillium. Tactillium is a cutting edge mobile application developed by a group of five high school students, which won Best in Nation in the 2014 Verizon Innovative App Challenge. The app, the first of its kind, is a full fledged virtual chemistry platform which allows curious minds to perform chemical reactions in an immersive 3D lab environment. In addition, the Tactillium app will soon come with additional classroom features including a teacher administration portal and advanced network-based assessment tools, creating a complete solution for integrating technology into the modern classroom. It is designed to function on student-owned smartphones and laptops along with school-owned tablets and computers.

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 a proper arrow glyph?

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.
