The 10 Best Smart Thermometers

The companion app for the Kinsa QuickCare (around $12) provides personalized recommendations on how to combat symptoms and whether or not it's time to consult a physician. Each family member has an individual profile, so it'll be easy to keep everyone's results straight.

The award-winning Bongmi Earmo (about $34) has an infrared sensor that delivers results in just one second, making it a great choice for use with sleeping toddlers who you'd prefer not to wake if you can help it. Plus, it has a large LCD screen in case you can't find your phone.

When you're trying to conceive, every bit of information that can help is welcome. That's why the Femometer Basal (appx. $29) automatically charts your cycle to predict the best window of fertility. It's also accurate to within a tenth of a degree.

It can be a struggle to get kids to sit still, especially when they don't feel good, but with the Elmo version of the Kinsa Ear (about $48), you can introduce a trusted friend, so the experience will be a little less scary as you check on them.

Ideal for women who are hoping to become pregnant, the Easy@Home Tracker (around $33) stores up to 30 records in its own memory, plus it gives you unlimited cloud storage. You can chart the changes in your body to pinpoint the most opportune days for conception.

The Withings Nokia Temporal (appx. $64) sends readings to your device via Wi-Fi, eliminating the annoyance of having to sync it every time you want to use it. Up to eight different people can store their results, making it a solid choice for large families.

Certain medications, like insulin, are temperature sensitive, meaning they can be ineffective or dangerous if not monitored. The MedAngel One (appx. $49) has a large built-in database that can inform you if something is too hot or too cold, even when you're away from home.

The Vavcase Wearable (around $29) is worn like a watch, allowing you to check the screen at any time, and can alert you based on parameters you set in the app. It's also rechargeable, so you won't have to be running out for batteries at an inopportune moment.

The Captain Eco Baby (around $25) can take measurements either in the ear or on the forehead, giving you options depending on how fussy your child is about certain areas. The info can be transmitted via Bluetooth along with dates and times, so you'll know exactly when you last checked.

The more data points you have, the better your analysis can be. That's why the TempTraq Intelligent (around $20) provides round-the-clock sensing in the form of a patch. There are both 24 and 48-hour versions that will immediately alert you of any spikes.
