KNOW WHAT TO DO NEXT Our care recommendations give you peace of mind with age-specific fever and symptom guidance - so you can know when it’s important to take extra precaution or see a doctor. REMEMBERS FOR YOU Easily track temperatures, symptoms and medication for everyone in your family! Remember details such as when symptoms began, how high the fever got, or when to give another dose of medication and share it with another caregiver or your doctor. Temperature data integrates seamlessly with HealthKit and the Health app. WHAT PARENTS ARE SAYING “The app tracks and organizes our family’s temps and symptoms and keeps the history. This is a wonderful app for a busy and sleep deprived mom!” “Hands down my favorite feature is that the app gives you suggestions on how to keep your little one comfortable and gives practical advice for a speedy recovery!” “The Kinsa app keeps all my data in one place and makes doctors appointments a breeze…” “We are a family of 6! Kinsa helps us keep track of everyone’s medical situation!” “This has to be one of the best products on the market for families, especially families with little ones!” The free Kinsa app works best with Kinsa's award-winning, pediatrician-recommended QuickCare, QuickScan, and Smart Ear thermometers, available for purchase online and in retail stores across the U.S. If you have an older Smart Stick thermometer that plugs into the headphone jack of your phone, please use the Kinsa Smart Stick app instead.

Verdict
The clearest difference is in-app purchases: Kinsa at none against Thermometer's 5. Kinsa also leads on rating (4.8 vs 4.4) and ratings volume (45K vs 24). Thermometer's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.5). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Thermometer sells 5 in-app purchases, starting at $6.99 per 7 days. Kinsa asks for nothing beyond the download.
Kinsa holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Kinsa has 45K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 50% of Kinsa's written reviews are positive against 55% of Thermometer's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
