Vikey is a next-generation Vietnamese keyboard, built for typing English and Vietnamese together.
Type an English word in the middle of a Vietnamese sentence and Vikey notices, fixes that word and switches mode for you. No language key, no more "deadlinê" or "meetingf".
• Switches between English and Vietnamese as you type, with over 99.7% of words right on real mixed English-Vietnamese text
• Familiar Telex typing, with modern (hoà, thuý) or classic (hòa, thúy) tone placement
• Word suggestions and auto-correct for missed keys, in both Vietnamese and English
• Works like the iPhone keyboard: key previews, hold a key for accents and symbols, hold the space bar to move the cursor
• Light haptic feedback (optional)
• Web address and email fields start in English
Private: the keyboard never goes online and collects no data. What you type never leaves your iPhone.
Free and open source. Also on the Mac at vikey.app.
