Tonos Polytonic Greek Keyboard

No more copying and pasting complicated diacritics from a website! Tonos is a polytonic Greek keyboard for iPhone and iPad. Designed for students, scholars, and anyone writing polytonic Greek, Tonos supports the full range of classical and historical diacritics across Classical, Koine, Byzantine, Katharevousa, and polytonic Modern Greek. All ten classical marks. Smooth and rough breathings, acute, grave, and circumflex accents, iota subscript, diaeresis, macron, breve, and the philologist's underdot. Combine them freely. Mutually exclusive marks, like acute and grave, or macron and breve, never fight each other. Two ways to type. Enter a vowel first and decorate it with one tap, or queue up the diacritics you want and apply them all to the next vowel. Whichever mental model you prefer, Tonos follows along. Spacebar trackpad. Drag across the spacebar to slide the cursor through your text, one character at a time. Fast drags accelerate, so you can cover distance without leaving Tonos to adjust the cursor. Three layers, one keyboard. • Letters uses the common Greek keyboard layout. • Numbers holds digits and punctuation, including ano teleia. • Archaic holds rare letters from languages that use the Greek alphabet: digamma, stigma, archaic koppa, koppa, sampi, san, heta, yot, sho, the kai ligature, and the Pamphylian digamma. Plus cursive and lunate letterforms for manuscripts and papyrology. NFC Unicode output. Canonically precomposed where Unicode provides a precomposed form. Letters with stacked breathings, accents, and iota subscript drop cleanly into any app, document, or database. No legacy codepoints, no lookup tables, no surprises for your downstream tools. Tonos Pro. An optional one-time upgrade adds three on-device polytonic assists. Auto-correct silently fixes missing or wrong diacritics when you hit space, return, or a punctuation key, drawing on a 1.3-million-entry polytonic dictionary merged from Classical, Koine, Byzantine, and Katharevousa corpora. Typeahead adds a suggestion bar with spell-check corrections for misspelled words, mid-word completions, and next-word predictions, powered by a language model trained on ~30 million polytonic tokens. Style Preferences lets you tune the editorial rules: enclitic-aware grave rule, iota subscript vs adscript, movable nu, elision, plus a three-way picker for the elision glyph (Combined, Koronis, or Apostrophe). No network access. The free keyboard is complete on its own, and your Pro unlock is a single non-consumable purchase that restores on any device signed in to your Apple ID. A quick setup note. Enable Tonos under Settings → General → Keyboard → Keyboards → Add New Keyboard, then tap the globe key on any keyboard to switch to it. Any apps that were already open before you enabled Tonos may need to be closed and reopened before the keyboard becomes available in them. This is an iOS behavior, not specific to Tonos.
