Field notes
The logging interface covers flow, pain, mood, sleep, tests, and notes, each with a severity option; symptom entry can also be searched or spoken. Predictions are framed as windows, with the page explaining that cycle lengths vary and showing how estimates change as entries accumulate. The site also describes widgets, Apple Watch actions, partner sharing, and a doctor report, alongside a default of keeping cycle data on the phone.
