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.

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.

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.

Fail. Plus Selling you location!

Horrible software & hardware.

At least now they’re selling your data maybe about your sick child to Clorox!

“Being able to target ads in this way is a big shift from even seven years ago, when the onset of cold and cough season meant buying 12 weeks of national TV ads that “would be irrelevant for the majority of the population,” Mr. Sarma said. The flu ultimately reaches the whole country each year, but it typically breaks out heavily in one region first and then spreads slowly to others.”

Original Kinsa stopped working when I went from an iPhone 5 to an iPhone 6. Kinsa never mentioned this in any app update notes. I complained so they sent me a replacement (eventually THREE REPLACEMENTS) that were all supposed to be iPhone 6 compatible. All failed with Error 3 4 despite two being the proper lot number. Why the sent me the first replacement that even they knew was incompatible? Beyond me. They even refunded my money and sent another Kinsa. It didn't work either and never replied to me. How are they in business if they can't even test the product before the ship it after multiple failures? I don't understand. A cheap drug store thermometer works better and is faster. The original Kinsa that sometimes worked with my iPhone 5 was slow and flakey. Totally unreliable. Who would have guessed the "iPhone 6 compatible" update would be worse and completely non-functional. Kinsa is 0-4. Hard to say that's a fluke.

Hello. To clarify, WE DO NOT SELL OR SHARE DATA ABOUT YOU OR YOUR FAMILY. Not now. Not in the past. Not ever. We take your privacy extremely seriously - because we are parents too.

We anonymize readings, group them together over a broad area, and then calculate whether illness is rising or falling over that broad area to create an illness signal. This illness signal is what we share with companies who align with our mission of keeping as many people as healthy as possible. This includes companies who make medicines to make sure that places where illness is high, don't run out of those vital medicines when and where they're needed the most.

Again, we do not share or sell your information, information about you, or information that could be used to identify you. Period.

Going back to the problems you've encountered with our hardware, we are deeply sorry for the frankly lousy experience you've had, and we’d be more than happy to make this right for you if you are open to it.

Our first thermometer model, the Smart Stick, the one that you may have had, came out many years ago, and we have since created a new thermometer which is far more reliable and compatible. It works independently from your phone and isn't subject to the myriad of settings on your phone which could interfere with readings. The new model is the Kinsa QuickCare and if you'd like to learn more about it, please visit KinsaHealth.com/QuickCare.

If you are interested in upgrading to this much newer and improved model, we can take care of that for you. If you could please reach out to us at KinsaHealth.com/ContactUs and mention your app review, our team will do whatever it takes to turn this around for you. Thank you for your consideration.
