## What is PRN Dose Timer?

When did I last take my pain reliever? When can I take it again?

• Log a dose with a single "Taken" tap
• Real-time countdown to your next dose
• A notification when it's time for the next dose

For anyone taking as-needed (PRN) medication — pain relievers, allergy medicine, etc. — who wants to avoid taking it too soon.
This app does not diagnose or prescribe. Set your dose interval according to your doctor's or pharmacist's instructions.

Free for 1 medication. A one-time ¥300 (or local equivalent) purchase unlocks managing multiple medications at once.
