Even Today. makes sure you never have a zero day. Every day is done by either any real workout that Apple Health logs or today's one required thing (e.g. 30 sit-ups) ticked off in the app. You can do it any time; earlier is encouraged. Each user sets a cutoff hour (default 21:00). When the cutoff arrives the day closes — it never drags on into the night. Only today exists: no streaks, no history, no calendar, no guilt. At midnight the sky resets.
