⌨️ KeySleuth measures physical key positions on a real keyboard — results from your phone's on-screen keyboard won't be meaningful. Connect a Bluetooth/USB keyboard for accurate diagnostics.
Targeted weakness training is now unlocked. You have enough history to drill your weakest letters, letter pairs and mistyped words. Look for the dumbbell icon in the toolbar.

Assign Keys
Layout
Click a key below, then press the matching physical key. Click it again to add another value -- a key can hold more than one character (its plain tap value, plus whatever a held layer/Fn key makes it produce); the first one assigned stays the main label, later ones show as corner labels. Use the panel underneath to remove a value. Assignments save automatically.

Weakness drills are listed here but not counted in your averages, charts or heatmap, because they're deliberately harder than normal typing.
