Typster is a fast, private keyboard built for people with vision and touch impairment. Switch between 13 languages with a single tap — English, Norwegian, Swedish, Danish, Finnish, German, French, Spanish, Italian, Portuguese, Dutch, and Polish — each with its proper layout (QWERTY, AZERTY, QWERTZ and more). Suggestions that make sense. Typster ranks word suggestions by how common they actually are, so the word you want comes first — not an obscure one. Autocorrect that respects you. Clear typos get fixed automatically as you type. Changed something you meant to keep? One backspace undoes it. Prefer to turn it off entirely? One switch in the language menu. Built for real writing. Contractions and elisions like “it’s”, “c’est” and “d’accord” are handled naturally. Long-press any key for accented characters. Private by design. Suggestions and corrections run entirely on your device. Typster works without “Full Access” — your keystrokes never leave your iPhone. • 13 languages, instant switching • Frequency-ranked suggestions • Conservative autocorrect with undo • Optional alphabetical (ABC) layout • Long-press accents and symbols • iPhone and iPad, portrait and landscape
