Titanboard

Titanboard is an input method for physical keyboard phones, supporting as low as Android 1.5 Cupcake.

Features

• Support for very low Android versions, down to 1.5
• Nimble and small; I set out to have the APK be at most 100 kB
• Each physical key can have several additional symbols, which the user can cycle by long pressing a given key. This also applies for alternate (alt) symbols
• 9 supported languages, with more planned (which are trivial to add)
• No hard to memorize key combinations; reasonably uses what the physical keyboard has to offer
• Clipboard management

Planned features

• Autocorrect
• Emojis
• Support for content other than text in clipboard
• Floating interface, which is placed over the current text in certain contexts, to save screen space

Supported languages

• English
• German
• French
• Italian
• Spanish
• Polish
• Russian (Phonetic)
• Greek (polytonic diacritics under Q)
• Arabic (Phonetic)
