LOG READINGS IN SECONDS • Enter temperatures in °F or °C, switch units at any time • Add medication and notes, such as symptoms, to each reading • Optionally record blood pressure (systolic/diastolic) with a reading • Text Size option and support for larger text UNDERSTAND THE TREND • Color-coded categories: low, normal, elevated, moderate fever and high fever • Charts and statistics by day, week and month • Calendar view to see every reading in context • Health insights that highlight highs, lows and changes REMINDERS • Medication reminders so you know when the next dose is due • Measurement reminders to check temperature on schedule REPORTS FOR YOUR DOCTOR • Create PDF and CSV reports of readings, symptoms and medicines • Share by email, messages or print before an appointment LEARN ABOUT FEVER • Short, illustrated guides: what a fever is, how to measure temperature correctly, first steps when someone has a fever • Fever in babies and children, and the warning signs that need a doctor or emergency care • Hydration and common medicines such as acetaminophen or ibuprofen • Every guide is sourced from trusted bodies including the NHS, CDC, WHO, AAP, NICE and Mayo Clinic IPHONE, IPAD, APPLE WATCH AND WIDGET • iCloud sync keeps your diary up to date on iPhone, iPad and Apple Watch • Apple Watch app: log a temperature and see history and insights from your wrist • Home-screen widget shows the latest temperature and its status • Apple Health integration reads and saves body temperature GET PRO • A one-time purchase, not a subscription • Family profiles: track fever separately for children, parents and anyone you care for • PDF and CSV export for your doctor • No ads IMPORTANT Fever Tracker does not measure temperature.

If you think someone is seriously ill, call 911 (or your local emergency number) right away.

Verdict
The clearest difference is ads: Thermometer at none against Fever Tracker's shown. Thermometer also leads on update cadence (fortnightly vs every 6 months) and ratings volume (411 vs 1). Fever Tracker's advantage is rating (5.0 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Thermometer sells 6 in-app purchases, starting at $5.99 per 7 days and Fever Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Fever Tracker holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Thermometer has 411 ratings behind it against 1, so its average is the more settled of the two.
Thermometer ships an update fortnightly, Fever Tracker every 6 months. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
