No — rounds work fully offline. ThumbDash ships with a built-in prompt generator, and the on-device AI engine is already bundled inside the app and ready at first launch. An internet connection is only needed for App Store purchases (or to optionally download the massive 1.7B Pro model).

ThumbDash runs a small language model (SmolLM2) entirely on your device to write a short, unique passage for every round, themed to the arena you pick. Nothing is fetched from a server, and no two rounds should read the same. If the AI engine is not downloaded — or ever fails — a built-in procedural generator steps in instantly, so the game never stalls.

Nowhere. Keystrokes, scores, and round history are stored only on your device. ThumbDash has no accounts, no analytics, and no servers — the only network activity is the optional one-time AI model download and Apple's own App Store purchase system. Your typing is completely private.

The free game includes two arenas (Deep Space and Zen Garden), Classic mode, unlimited rounds, and the bundled on-device AI engine. Supporter ($2.99/mo) and Pro ($14.99 lifetime) both unlock all 15 arenas, all 5 modes (including 30s/60s Sprint, Daily Thumb, and Ghost Race), full stats history with trends, watermark-free share cards, and the optional 1.7B AI model. To restore a previous purchase on a new device, tap Restore Purchases on the upgrade screen while signed in with the same Apple Account. Supporter can be managed or cancelled any time in your Apple Account subscription settings.

ThumbDash requires iOS 17.0 or newer and runs on iPhone and iPad. The optional AI engine is tuned to run comfortably on modern devices; on older or lower-memory hardware, ThumbDash automatically falls back to its built-in prompt generator, so every device gets the full game.

Net WPM counts correctly typed characters (5 characters = 1 word) per minute. Accuracy counts every forward keystroke, so a mistake always costs you even after you fix it. Mistyped characters advance the cursor and must be backspaced and retyped to score as correct — autocorrect, predictive text, and paste are all disabled, so every word is thumbed out honestly.
