Tools that measure, and decline to guess.
Software that reports what it found in your own record — on your own device, with the method beside the number.
Years, not the last seven days
Some signals only mean anything over a long run. Daycurve reads the whole record and says so when it is too short to carry a measure.
Measurement, not prediction
Every number was asked of the record. Where it cannot support a claim, the screen names what is missing.
Nothing leaves the device
A property of the binary, not a promise in a policy. There is no networking code to send anything anywhere.
The method comes with it
Any figure opens to show how it was computed, with the caveat travelling alongside.
What was measured, and what was published, kept apart
Your own drift carries its interval. A published finding describes large groups over many years, and is never a statement about you. The screen keeps the two visibly separate.
