TypeWell
A touch-typing trainer built for iPad. Twenty guided units take you from f j on the home row to numbers, symbols and a full-keyboard sprint; then drill the letter pairs English is really made of, or type real passages and timed tests. Tap the on-screen keyboard, or pair a Bluetooth one and go full speed. The next key lights up in its finger colour, a hand guide shows which finger to use, and every keystroke is measured: wpm, accuracy, consistency, a per-key heatmap, a practice streak. Light and dark themes, QWERTY/Colemak/Dvorak. Pure HTML and JavaScript, no build, works offline.
