Do your children often have a fever? Do you sometimes get confused remembering when exactly it started, how it progressed and what other symptoms occurred? Having trouble explaining the exact course of the fever to the pediatrician? Keep track of body temperatures and medication for your whole family with Feevy. TEMPERATURE, MEDICATION AND NOTES With Feevy you can not only record temperature measurements, but also track medications and enter text notes. This way, you can verify if medication was effective and capture additional information, e.g. regarding the patient’s condition. Be perfectly prepared for your next visit to the doctor! BEAUTIFUL CHARTS Entering data is worthless if you can’t analyze it later. Feevy comes with a beautiful and very detailed interactive chart, which makes it easy to get a quick overview, as well as to analyze temperature curves in more detail. You can freely zoom and pan it to see all the details you need. PRINT AND SHARE YOUR DATA Of course you can also print and export your data. This way you can bring your fever curve with you to the doctor or even send it via e-mail. The PDF contains all measurements, medications and notes, as well as a full-page chart showing the temperature curve. TRACK MULTIPLE PEOPLE Feevy lets you track the fever curves for multiple people. It is perfect for keeping track of your children's conditions and illnesses. To represent your family with some personality, Feevy comes with a set of cute profile icons to choose from. SYNC WITH FAMILY MEMBERS Especially if you use Feevy to track your kids' illnesses, you will appreciate its sync functionality. No matter who measures the temperature or administers medication, both parents will always see the same data on their devices. UNIVERSAL APP Feevy supports both iPhone and iPad, including iPad multitasking (Slide Over and Split View). Use your iPhone while on the go or to quickly enter a new measurement, and use the iPad to have a detailed look at the charts. Feedback is always welcome: feedback@feevyapp.com or via Twitter @feevyapp. IMPORTANT In case of fever and sickness, please always consult your doctor. Using this app to track body temperature and symptoms is not a substitute for a visit to the doctor! OF COURSE YOU CANNOT MEASURE YOUR BODY TEMPERATURE WITH THIS APP! You can only record, visualize and archive the measurements obtained with a fever thermometer.

Verdict

The call

The clearest difference is price: Kinsa at Free against Feevy's $2.99. Kinsa also leads on rating (4.8 vs 3.5) and update cadence (monthly vs every 14 months). Feevy's advantage is review sentiment (65% vs 51%) and device support (3 vs 1). On ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Kinsa is free to download; Feevy costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Kinsa holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Kinsa has 45K ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 65% of Feevy's written reviews are positive against 51% of Kinsa's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Feevy ships an update every 14 months, Kinsa monthly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
