- iOS users tracking a deadline-driven task
- Worth noticing
- Its pressure calculation uses sessions remaining, days left, recent pace, and sessions actually completed—not just a countdown.
Field notes
The page says the app works offline and needs no account; it describes four task inputs, with completed sessions and recent pace informing a forward forecast. Steady Burns credit completed quarters, Deep Dives count only when finished, and a Vent becomes available at Boiling; the timer can keep running while the app is closed. Finished sessions earn shards for cosmetic volcano, timer-ring, and sky options, alongside a streak and task history.
