Glyphdeck: Science Keyboard

Glyphdeck puts scientific symbols within reach, in your own writing and in other apps.

SYMBOLS, WITHOUT THE SEARCH ENGINE Find 91 math operators, Greek letters, unit signs, arrows and logic symbols by name, symbol or Unicode value. Tap to copy. Star the marks you use most.

WRITE IT ONCE, USE IT AGAIN Compose plain-text formulas and lab notes with symbols inserted at the cursor. Save, reopen, edit and rename reusable texts on your device. Copy, share or export a named UTF-8 TXT file. Four example lines help you start a measurement, circuit, calculus or set-notation note.

A KEYBOARD FOR OTHER APPS Add Glyphdeck Symbols in iOS Settings, then switch with the globe key. Browse five symbol groups with page controls, space, delete and return. Full Access is not required. Secure fields and apps that block custom keyboards use the system keyboard. Symbol appearance depends on the receiving app and font.

One purchase. No subscription, ads, account, analytics, tracking or developer-server upload. Favorites, recent symbols and saved texts stay on your device unless you choose to copy, share or export them. Glyphdeck inserts plain Unicode; it is not an equation renderer or calculator.
