Vietnamese

Flikzi types Vietnamese with plain letters. There is no Telex: you don't type marks or tones yourself. Type the letters of the word, and Flikzi puts in the word with its tones and marks (â, ê, ô, ă, ơ, ư, đ and the five tones).

• While you type, your plain letters show in the text. The strip above the keys leads with the word that space will use, with its tones. Other words with the same letters follow: tap the one you meant.
• The next word can change the one before it, which helps with short words that share letters: type cam on and you get cảm ơn. A word you picked from the strip never changes.
• Hold a vowel for all its toned forms, when you want one letter exactly. Slide to it and lift.
• If Flikzi put in a word you didn't mean, swipe left on the space bar straight after it. Autocorrect and suggestions

Everything runs on your phone.
