Math Time

A streak is consecutive days with at least one finished run, either way of answering; a day skipped ends it.

Your ink is cut into digits by the gaps between strokes, each digit is scaled to the size of a printed one, and a small neural net — trained on 60,000 handwritten digits and running entirely on this device — says which digit it most likely is. Nothing you write leaves the phone; only the answer does.

It is generous towards the right answer and only towards it: if the correct digit is a reading the net finds plausible, it is accepted, even when it was not the net's first choice. A clear 7 when the answer is 1 is still a 7.

If the pad keeps misreading one digit, write it a little larger and leave a clear gap between two digits. The cross shows what was read.
