When baby’s sick, the last thing a parent wants is to wake him or her for a temp check. FeverFrida checks in on your babe every four seconds without waking him or her, thanks to a bitty Bluetooth monitor and patch placed under the arm. The FeverFrida will alert your smart phone when the temp goes above a predetermined threshold and continuously stores data for pediatrician visits and medicine dose reminders. Think thermometer meets very smart baby monitor!

FeverFridaTM The iThermonitor is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from FeverFrida is the best! FeverFrida is on the high end of the price scale but, when compared to other instant thermometers, it really is not that expensive. To be able to reliably see what baby’s temperature is, especially at night, without having to bother baby or wait for the thermometer reading is well worth the cost. If baby is in a separate room you will not be able to receive alerts should baby’s temperature reach a high level. But you can see the entire night, or days, worth of temperatures, which you can not do with any other thermometer. You do need to be within 10 feet of baby to receive the data. Personally I think the positives outweigh the negatives and would strongly suggest the FeverFrida.

Rated 5 out of 5 by from This is such a huge help and relief for my family...my daughter has a periodic fever syndrome and gets fevers every 3-8 weeks...this works so well and keeps my mind at ease. The app is very easy to use and keeps us updated constantly!

I just got my toddler a feverfrida, and I love it! We used it last night and it was so reassuring for me. My only issue is that it doesn't seem to stick to him very well. Is there something else I can use to stick it on him?

Thank you for reaching out about Fridababy's Feverfrida adhesive patches. We do not have other alternative than The Feverfrida Patches, unfortunately we cannot recommend any adhesive patches which why we advise to contact your doctor for alternative for health reasons. If you would like you may use 2 patches to make a big patch to fix the sensor on your child. If you would like to use a band aid to try & prevent from the Feverfrida to move out of place, you would need to contact your child's pediatrician if you will be using for a long period of time due to skin irritation. Please be sure the armpit is dry at all times once placing the Feverfrida with the patch. The best way to prevent this would be to make sure the FeverFrida Adhesive Patch is pressed tightly pressed against the battery compartment. We recommended to disregard the patch after every 24 hours, do not repaste adhesives. If an adhesive is already folded over, a new patch is required.

Can the iThermonitor feed in the body temperature to the health app found in iPhone? I tried by the health app would not capture any temperature. Thanks

Asked by: cristalle
Thank you for contacting Fridababy! The iThermonitor cannot be feed into the Health app. To monitor the temperature you would need to download the "iThermonitor" app from your App/Google Store.

I am trying to determine the best placement I read "armpit skin" in the manual but all the pictures seem to be at or slightly below nipple Level. Also is it better to place it vertical or horizontal?

Asked by: Daniellep

May sound like a silly question but can this thermometer be used on a baby with a pacemaker? Baby pacemakers are placed in the upper abdomen region. Wondering about any interference.Preparing for a baby with complete heart block so this is very important!

Asked by: boymomCJ
Thank you for reaching out regarding Fridababy's FeverFrida! We recommend that you reach out directly to your physician about this matter. Please let them know that the data between the FeverFrida and the iThermonitor app is transmitted via low-energy Bluetooth to see if there will be any impact to the pacemaker.
