Editor's Note: This review was refreshed on March 19, 2026, with new testing and new popular models from GoodBaby, Frida Baby, and Braun to the lineup.
For families, schools, or anyone looking for a reliable, touch-free scanner, we love the GoodBaby No-Touch FC-IR202. This low-cost thermometer tops the charts in ease of use and speed, delivering instant, accurate results. Plus, the large display lights up green, orange, or red to indicate whether a fever is present. One tester noted, “I love how quick and simple it is to use! Just point it at the forehead, press the button, and boom, your color-coded result is ready.” The touch-free design also helps reduce the spread of germs — an ever-so-helpful attribute when caring for potentially ill individuals.
The FC-IR202 is the most accurate touchless model we tested, but like all infrared thermometers, is sensitive to sweat, smudges, and the ambient temperature. This can throw the results off if you were just outside, have thick bangs, or wear hats. One reviewer said, “I had to make sure the sensor and my kid's forehead were both clean for the best accuracy.” If you need something more reliable in the face of sweat or hair, the Frida Baby 3-in-1 has options for both forehead and ear scans, though it's not nearly as user-friendly as the GoodBaby.

The Vicks SpeedRead is an excellent choice for anyone who needs a cheap option with reliable results. It's one of the most accurate models we tested, delivering consistent, dependable readings we could trust every time. Plus, it's single button design and crisp color-coded display keep things simple and intuitive, while its waterproof tip makes cleanups a breeze. With three different ways to read, the Vicks is suitable for infants, the elderly, and everyone in between. One reviewer noted, “For the few times a year I need a thermometer, the Vicks is simple and accurate, which is perfect for my needs.”
The biggest downside is the lengthy read time. One parent said, “I find my child has a hard time sitting still for the full eleven seconds.” We also don't love the rigid tip, which can make oral and rectal readings less comfortable than probes with a soft, flexible tip. If you need something faster, consider the touch-free GoodBaby FC-IR202. Or, the upgraded Vicks SpeedRead ComfortFlex is a more comfortable probe-style option, but both will cost you more. All in all, it's hard to find a better value than classic SpeedRead.

Taking your little one's temperature can sometimes feel like you're wrangling a squimy noodle, but the FridaBaby 3-in-1 keeps things short and sweet. This combination forehead, ear, and object scanner is the most accurate infrared thermometer we tested, delivering instant readings right on par with medical-grade probes. You do have to touch the forehead, so it's not technically touch-free, but it's just as convenient, even on sleeping kids. One parent noted, “I like that I can use the adult mode on myself, or the baby mode on my child, which makes it useful for the whole family.” We also love the large display, which lights up green, orange, or red to indicate a fever.
The biggest hurdle is learning how to operate this thermometer. One tester complained, “The buttons aren't clearly labelled, so I had to read the manual to figure out how to silence the sound. But once I did that, it was smooth sailing.” It's also pricey. If you need something cheaper and more straightforward to use, the GoodBaby IR202 is a great alternative, though it lacks the infant setting. And, for newborns, we like the Vicks SpeedRead. Still, if your budget permits, we think most families will love the quality and versatility of the Frida Baby.
The Frida Baby 3-in-1 is perfect for babies, toddlers, and big kids who want the accuracy of a traditional stick thermometer with the convenience of a speedy infrared model.
Easy-to-use controls and fast, reliable reads are what make the Braun ThermoScan 5 our favorite ear thermometer. One tester noted, “What I appreciate most about this thermometer is its simplicity. There are no fussy controls or hidden menus.” Sure, it's pared down design means there's no light-up display or fever alert like the upgraded Braun ThermoScan 7, but it nails the basics, which is all some users need. It's suitable for anyone over six months and has a stability sensor, which is a big help for getting a proper read on squimy kids. Plus, the lens filters make cleanup as simple as the push of a button — because who wants to deal with sticky earwax?
Can I use my ear thermometer on a newborn? Braun markets their ear thermometers for babies as young as 0-3 months, but most pediatricians recommend waiting until kids are at least 6 months to take an ear reading. This is because young babies' ear canals are simply too small to get an accurate read.
However, you must pull the ear back to get an accurate read, which might be tricky when using it on yourself or a fussy toddler. One reviewer mentioned, “My three-year-old refused to let me take an ear measurement when he was feeling crummy.” Plus, the ongoing cost of replacement filters adds to the already high price tag. The Frida Baby 3-in-1 adds an optional forehead mode for times when ear scans aren't ideal and doesn't require disposable filters, but it isn't as easy to use. Ultimately, if all you need are simple, accurate readings, you'll love the ThermoScan 5.

If you need more than just a basic thermometer, the Braun ThermoScan 7+ Connect is an easy-to-use and reliable medication, symptom, and temperature tracker in one. No more scribbling on notepads or forgetting the last time you took your medication, the ThermoScan 7+ logs it all right on your phone. One tester said, “I think this thermometer is great for caregivers managing medical conditions, families with young kids who get sick often, or anyone trying to conceive.” Plus, the age-based fever indicator, nightlight, and disposable lens filters are thoughtful touches that make temperature checks that much easier, day or night.
The 7+ scored well across the board, but its dependable performance comes at a crazy high price. Another reviewer said, “It's slow to start up, which I found frustrating, but the actual read time is at least fairly quick.” If you need to cut costs, the Kinsa QuickCare Smart is a much more affordable, stick-style health tracker that doesn't require ear pulling, but it's glitchy. In the end, we think the ThermoScan 7+ is a great option for users who don't mind paying extra for a reliable, feature-rich model.

How We Tested
At GearLab, we purchase everything at retail price and never accept manufacturer samples, so you get unbiased information to help make an informed decision. Over the years, we have researched dozens of different thermometers and tested 19 different models to find the best. We use each thermometer in our home for weeks on end, testing each day how easy they are to use on ourselves and on impatient little ones. We take countless scans and compare the measurements to medical-grade probes. And we take note of special features that may be important to users. Scores for individual test metrics are weighted and combined to produce an overall score.
The thermometers in this review were judged by three rating metrics:
Accuracy (50% of overall score weighting)
Ease of Use (35% weighting)
Speed (15% weighting)
Even minor differences, like how soft and flexible the tip is, make a huge impact on our evaluation of comfort and overall ease of use. Credit: Lissette Velasquez

Analysis and Test Results
Below, we highlight the top contenders in each metric and those that fall short. The intent is to provide more granular information so you can assess each product based on what's important to you.
Worse Value
Better Value
What's the Best Value?
Value is what you get relative to what you pay. Based on our testing, the best value options include the GoodBaby FC-IR202 and the Vicks SpeedRead. If rapid reads and ease of use matter most to you, you'll appreciate the GoodBaby's touch-free design. Even if it isn't quite as accurate as pricey versions used by hospitals, it's reliable for routine checks or sick-day monitoring. Or, if you're looking for the most accurate reads at the most inexpensive price, the SpeedRead fits the bill. Its classic stick design proves you don't need fancy features to get dependable results.

Accuracy & Consistency
Accuracy is the most important aspect to consider when choosing a thermometer, because even small errors can affect care decisions. To assess accuracy, we measured our temperature with each model, then compared the measurement to that of the Welch Allyn Sure Temp Plus 690 medical probe, a gold-standard model widely used in hospitals and doctors' offices. We repeated this test numerous times on our forehead, in our ears and mouths, and under our arms to see how consistent the readings were.
The most reliable models include classic stick options like the Vicks SpeedRead and Boncare 10 Second as well as the Frida Baby 3-in-1 point-and-shoot infrared thermometer. All three options gave consistent measurements at every body site, with averages within 0.2°F of our control probe. They are also some of the cheapest options in our lineup, proving you don't have to spend top dollar for top-notch accuracy.

The IR202, ThermoScan 7+, and ThermoScan 5 also performed well, with readings that stayed within 0.2°F to 0.3°F of our control probe. We noticed some slight variability between the left and right ears, which affected the ThermoScan's score, but when used in the same ear each time, we saw great consistency.

The ThermoScan 7 and Frida Baby have unique child modes that make them especially reliable tools for parents who prefer infrared thermometers. The Frida's baby setting adjusts the reading to account for an infant's thinner skin, reducing errors typical of other forehead scanners. And the Brauns' newborn and toddler modes adjust the fever threshold to account for kids' naturally higher body temperatures.

Read the manual for the best accuracy: Modern thermometers don't just report the sensor's raw readings; they use complex algorithms to estimate your body's core temperature. They account for factors like the measurement site, skin thickness, and room temperature. But if your skin is sweaty or the thermometer isn't positioned correctly, it can throw the reading off. So, take a minute to read the instructions to avoid misleading readings.
When used with proper technique, most other thermometers fared well, and we think all but the GoodBaby Infrared FC-IR100 are reliable options. We've tested several IR100 units over the years and found that while some are great, others are incredibly inconsistent or inaccurate, sometimes swaying by over 3°F from one reading to the next. When it works, it works well, but when it doesn't, it's pretty darn bad. It's a gamble we'd rather avoid.

Some infrared thermometers in our review, namely the IR100, IR202, and Frida Baby, also feature an object mode, where you can measure things like bottle temperature, bath water temperature, or room temperature. Although convenient, it's not very accurate and can be off by several degrees. So, we wouldn't rely on these measurements for safety-critical tasks.

Ease of Use
An easy-to-use thermometer makes daily health monitoring or fever checks on toddlers simpler. To assess ease of use, we scored how comfortable each model feels, how intuitive the controls are, how easy the display is to read, and how simple it is to clean or change the batteries. We also gave extra points for thoughtful features that make temperature checks less stressful.
Our favorite thermometer to use, by far, was the GoodBaby FC-IR202. It's about as comfortable and hygienic as it gets, with a touch-free design that even little ones won't protest. The buttons are clearly labelled, and the large display lights up green, orange, or red, taking the guesswork out of fever checks. For middle-of-the-night reads, you can mute the sound. And it can recall up to 35 previous reads, which makes it easy to track temperature trends The FC-IR 100 has all of the same benefits when used in forhead mode, but lost points because the ear mode a bit more uncomfortable than other ear models.

The Braun ThermoScan 7+ smart ear thermometer was another favorite, with loads of features that make temperature taking and health tracking easy. With the Braun app, users can track medications, symptoms, and temperatures for multiple family members. The device also has a color-coded fever indicator, a nightlight, and a silent mode for easier nighttime reads. Plus, the disposable lens filters make cleanups easy. However, the startup is a little slow, and you must pull on the ear, which isn't as straightforward as a forehead scan.

If you don't need all the extra features, the ThermoScan 5 ear thermometer and Vicks SpeedRead oral, underarm, and rectal thermometer are excellent basic, easy-to-use options. They're a bit more invasive than touch-free forehead scanners, but the controls are fuss-free. No confusing startups or hidden menus, just simple, straightforward temperature reads. Plus, they're easy to clean, too.

Speed
When you're not feeling well, waiting for a thermometer to take a reading can feel endless. To ensure the most comfortable and convenient experience, we timed how long each device took to display a temperature. We repeated the experiment five times at each measurement site, then averaged the results.
All the infrared thermometers scored high in this metric because they provide near-instantaneous results, while classic stick-style thermometers scored lower because they take around 10 seconds. Still, modern stick thermometers are a big improvement over mercury-style thermometers of the past, which take several minutes to develop.

The fastest models include options from GoodBaby, Frida Baby, iHealth, and Exergen, which all took only 1 second to produce a reading. The Braun lines were a little slower, but still pretty darn quick, measuring in at 2 seconds. All of these options are the best choice for quick, stress-free scans.

How to Choose The Best Thermometer
Choosing the right thermometer can make a big difference in keeping your health in check. These tips will help you find the best one based on your needs and budget.
Infrared or Stick?
Stick: cheap and accurate. If you don't mind a more lengthy, invasive approach, stick thermometers are easily the best bang for your buck. They're highly accurate and can be used orally, rectally, or under the arm, making them suitable for all ages. However, they're less convenient for restless kids and must be carefully sanitized to prevent the spread of illness.

Infrared: convenient. Infrared thermometers are a fast, low-fuss option that comes with a higher price tag. Touchless forehead models are perfect for school or office settings and minimize the spread of germs, but their accuracy is conditional. Sweat, hair, hats, and other environmental factors can influence the measurement. Ear thermometers are more reliable, but proper placement is crucial, which can be difficult to achieve with squirmy kids.

What's The Best Measurement Site?
Rectal measurements are the most accurate, but let's be honest, they're awkward and uncomfortable. Oral, ear, and forehead measurements are more comfortable and can still be highly accurate, but you must follow the manufacturer's recommendations to a tee to avoid skewing the results. Armit readings are convenient, but the least accurate, which can make it difficult to identify a low-grade fever. So, select the site that balances your needs for comfort and accuracy and is appropriate for your child's age.
AAP guidelines for temperature taking: Adult measurements can be taken at any body site, but kids are more restrictive. Below are the AAP's recommendations. 0-3 months: Rectal is best, though forehead scans can be used for quick screening. Armpit reads are less reliable. 6+ months: Ear canals are now large enough to support an ear thermometer. 4+ years: Kids can now hold a stick thermometer under the tongue to get an oral read.
Underarm measurements are convenient, but they are the least accurate method. Credit: Lissette Velasquez
What Features Should I Look For?
Some features just make life easier, but they often cost extra. Thermometers with memory can help gauge the progression of fever. A large, light-up display is easier to read in low light during nighttime checks. An app can track symptoms and temperature trends. And disposable covers provide a more hygienic experience. Consider if these are things you need and if you're willing to pay extra for them.
