An as-needed medication tracker that remembers the last dose for you
Cadence logs the medications you take only when you need them. You set the spacing and the daily limit, and it shows when you last took one. Free on iPhone and Apple Watch, with no account.
What it does
Your own spacing
Set a minimum gap between doses, as your label or prescriber says.
A 24-hour limit
Set a maximum number of doses in any rolling 24 hours.
A gentle check, never a block
If you log inside the gap or over the limit, Cadence asks whether to take it anyway and lets you log it. It does not stop you.
A countdown on your Lock Screen
For as-needed doses with a gap, and for medications taken every few hours, the Lock Screen and Dynamic Island count down to the next dose when it is within eight hours. New in 1.9.29. Turn it off in Settings, under Reminders.
Taken today, at a glance
The as-needed card shows how many you have had today and when you last took one.
Scheduled and as-needed together
A daily medication can also allow an extra dose when you need one. The Medications list keeps scheduled and as-needed in their own sections.
Log from your wrist
Record an as-needed dose on Apple Watch.
A history per medication
Every dose, newest first, on one screen.
In your doctor report
The PDF report lists as-needed use separately from scheduled adherence. Pro.
