After each day's sitting you answer one question — how you feel — on a six-word scale. Each word maps to a 0–4 'decentering' score from the mindfulness literature (calm and bright score high, restless and heavy low). Averaged over your last sittings, that is your Calm Score, shown as a percentage.

Every fourteen days you re-take the two short questionnaires from onboarding: the WHO-5 wellbeing index and the GAD-2 worry check. These are validated instruments, and comparing them to your first answers is the closest thing to an honest before-and-after that a self-report app can give.

Your Breathing Benchmark is re-taken every seven days. Natural inhale and exhale length, and a single gentle breath hold, tend to lengthen as practice takes — and the course re-times its breath techniques to the new numbers each time.

Streaks and session counts are shown, but they are the least important of the four. They measure showing up, which matters, but they don't measure whether it's working. The other three do.
