A dose log with no streaks to break
Record the dose, date, time and how it felt. Early, late or skipped, every entry saves, with no streaks to break and nothing that makes you feel behind.

Doses do not always happen on the planned day, and most trackers treat that as a failure. Doser just records what happened.
How it works
Open Doser and tap to log a dose.
Record the dose, the date, the time and how it felt.
Save it. Early, late or skipped, every entry stays in your history.
