Let Kinsa guide you from the first sign of sickness through recovery and beyond! As seen in Apple’s “Parenthood” commercial.

Easily track temperatures, symptoms and medication for each family member. 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.

Kinsa’s new Care Recommendation feature gives you peace of mind with age-specific fever and symptom guidance in real-time - so you can know when it’s important to take extra precaution or see a doctor.

The free Kinsa app works best with one of Kinsa’s award-winning, pediatrician-recommended thermometers, available for purchase online and in retail stores across the U.S.

Early warning always worth knowing.

My old thermometer did not work and every store I checked in Madison Wisconsin and even on-line stores were out of thermometers a few weeks ago. I am 80 years old and like to work for the elections; the April primary was coming up - I was helping mail out absentee ballots downtown. I finally ordered a Kinsa and was looking forward to some “peace of mind” knowing I had technical proof of no fever. (Retired nurse in infection control). Impressed when Rachel Maddow explained your data program. I am encouraging my own friends and my adult children to join me in this so simple daily act while this virus rages. Wisconsin carried out a foolishly-timed election which may result in many infected people here in the next two weeks. I am happy to have a reliable thermometer to be an early warning of illness and need for testing.

Dangerously inaccurate

We bought this thermometer for our newborn who is under 2 months old. For newborns under 3 months, a fever of 100.4 is an emergency. This thermometer indicated that our newborn had a fever on 3 separate occasions, one reading as high as 100.9. This caused us to go to the emergency room where they drew blood (which is very hard on a baby under two months). They had to try twice to draw her blood because her veins are so small. They also took urine samples to rule out a UTI and talked about a possible SPINAL TAP to find out if she had meningitis! At this point, we wondered if the thermometer was the problem and we bought a rectal thermometer at CVS. The Kinsa thermometer consistently read high compared to the CVS thermometer, as high as 2 degrees. Based on the CVS thermometer, our baby never even had a fever! This was also verified at the hospital when they re-checked her temperature. This thermometer is highly inaccurate and needs to be taken off the market. Had we not thought to verify its accuracy, we may have put our newborn through more invasive procedures (spinal tap) that were unnecessary.

Easy to useand well made

I bought four. Two of the sticks and two of the ear model. I’m mailing a set of them to my daughter in Boston. I’m in a rural setting and she is in a big urban area. She has roommates and I have family here. It seemed reasonable to have the larger thermometer for others in our homes and the stick for personal use. It is quick and easy to use. I am very pleased with them and will feel better knowing my daughter has them too. I really like the idea of data sharing to catch infection in hot spots, or areas that may be heating up. I hope you will continue to make this side benefit of data available to folks and make a nice forecast of healthy areas vs not so healthy areas before they get bad. It is so important and will, I believe, save lives. Carry on!!!
