Track fever doses safely
2 min read·Updated May 15, 2026
The Fever Tracker helps you safely alternate Motrin (ibuprofen) and Tylenol (acetaminophen) by logging each dose and showing a live countdown until the next safe dose.
How the timers work
After you log a dose, PillArm shows when each medication is next safe to give: Motrin every 6 hours, Tylenol every 4 hours by default.
Always follow your pediatrician's weight-based dosing. The tracker is an organizational aid, not dosing advice.
