Fast, Flexible Dual-Mode Readings
9.2/10The GoodBaby FC-IR100 delivers a one-second reading in both ear and forehead modes, making it one of the quickest thermometers in its price tier. For a restless toddler, the ear probe can slip in and read before they notice, while the forehead mode works even from a slight distance. In comparison, the iHealth PT3 offers similarly fast no-touch readings, but the GoodBaby adds the option of an ear mode for older kids who won't sit still. The dual-mode flexibility is a real advantage for families managing different-age children or adults who prefer ear readings.
If you need a thermometer that works quickly for squirmy kids and adults, the GoodBaby is ideal; if you only need no-contact forehead readings, the iHealth PT3 is a slightly more accurate alternative.
Accuracy and Consistency
8.5/10The GoodBaby thermometer boasts ±0.2°F accuracy in body mode, which is adequate for home use but not hospital-grade. In our analysis of thousands of user reviews, many parents report consistent readings within 0.5°F of their pediatrician's measurements, though some note that ear readings can vary if the probe isn't positioned correctly. In comparison, the iHealth PT3 uses a tri-point sensor to gather 100+ data points per second, often yielding slightly more consistent no-touch results. However, the GoodBaby's forehead mode is generally reliable when used per instructions. For the price, its accuracy is solid.
If you can tolerate a slight occasional variance and follow ear-placement instructions closely, this thermometer performs well; for demanding clinical-grade consistency, consider the iHealth PT3 at a higher price.
Ear Mode: Not for Infants
6.5/10The ear mode on the GoodBaby FC-IR100 is not recommended for babies under 12 months, as pediatric guidelines and community feedback both warn that ear canals are too small for accurate measurements. Across Reddit threads in r/beyondthebump and r/NewParents, users consistently report that ear thermometers give unreliable results on infants, with variations of over a degree. If you need a thermometer for a newborn, a rectal digital thermometer like the FridaBaby 3-in-1 is the safest and most accurate option. For older children and adults, the ear mode works well, but skip the GoodBaby if infant use is your priority.
This thermometer is a poor choice for infants; use a dedicated rectal thermometer instead, and consider the GoodBaby only once your child is over a year old.
Everyday Use and Display
9.0/10Using the GoodBaby thermometer is about as simple as it gets: point, press, read. The backlit display is clear in the dark, with large digits and a color-coded fever indicator (green for normal, red for high). The memory recall button lets parents track a fever over time without needing an app. While it lacks the smart connectivity of the Kinsa QuickCare, many users in parenting subreddits appreciate the simplicity and lack of Bluetooth headaches. The auto-off feature saves battery, and the whole unit wipes clean easily — though it isn't waterproof, so avoid submersion.
If you want a no-fuss thermometer that works without an app and is easy to read at 3 a.m., the GoodBaby is a great fit; if you need app tracking, upgrade to Kinsa.
Memory and Battery Life
8.0/10With 35-reading memory, the GoodBaby outperforms many pricier competitors that store only the last reading. This feature is handy for tracking fever progression over a day or sharing data with a pediatrician. However, it relies on two AAA batteries (included), which are not rechargeable, and some users report low-battery alerts even with fresh batteries — a minor annoyance. Compared to the Kinsa, which relies on phone memory and Bluetooth, the GoodBaby's on-device storage is more reliable but less sophisticated. Battery life is adequate for typical family use, lasting several months with daily checks.
The generous 35-reading memory is a standout budget feature; if you can overlook occasional battery quirks, it's a valuable asset for monitoring fevers at home.

Reddit Community
On parenting subreddits like r/beyondthebump and r/NewParents, the GoodBaby thermometer is frequently mentioned as a budget-friendly alternative to the iHealth PT3. Users appreciate its ear+forehead dual mode for older children, but many caution that ear mode is not suitable for infants. The 35-reading memory is often cited as a useful feature for tracking fevers without an app. However, some Redditors note that forehead readings can be slightly inconsistent and advise using it as a screening tool rather than a definitive diagnosis.
YouTube Reviewers
In a Best Baby Thermometer video by Best Reviews, the GoodBaby No Touch Thermometer ranked second overall, praised for its sub-second readings, ergonomic design, and memory storage. The reviewer highlighted that its backlit display and fever color alerts made it easy for sleep-deprived parents to interpret results. The video also noted that the dual-mode capability gave it an edge over purely forehead-based models, but cautioned that ear readings should be used cautiously in very young children.
Expert Publications
Tom’s Guide names the iHealth PT3 as the best overall thermometer for its no-touch accuracy, while Consumer Reports emphasizes the importance of proper technique in ear thermometers. Although the GoodBaby FC-IR100 isn't directly tested by these outlets, its design mirrors many recommended features: fast readings, dual modes, and a large display. Experts universally advise against using ear thermometers on infants, which aligns with the GoodBaby’s own age recommendations.

Frequently Asked Questions
Is the GoodBaby Ear Thermometer worth the price?
At under $20, the GoodBaby FC-IR100 offers excellent value for families with children over one year old. It combines ear and forehead modes, a 35-reading memory, and a backlit display—features typically found in more expensive models. However, if you need a thermometer for an infant, a dedicated rectal thermometer is safer and more accurate.
How does the GoodBaby compare to the iHealth PT3?
The iHealth PT3 is a pricier no-touch forehead thermometer with tri-point sensor accuracy, while the GoodBaby adds ear mode and 35-reading memory at a lower price. The iHealth may give slightly more consistent readings, but the GoodBaby is more versatile for families with older children who prefer ear checks. For infants, neither ear mode is recommended; the iHealth is a safer bet.
What problems does the GoodBaby thermometer have?
Ear mode readings can be unreliable for babies under 12 months due to small ear canals. Some users report occasional inconsistency in forehead readings, and a few note a persistent low-battery alert even with fresh batteries. The unit is not rechargeable and lacks app connectivity, which may disappoint tracking enthusiasts but keeps the price low.
Can I use the GoodBaby thermometer on a newborn?
No, pediatricians and communities like r/beyondthebump strongly advise against ear thermometers for newborns. For a baby under 3 months, a rectal reading is the gold standard for accuracy. The GoodBaby is suitable for children over 12 months and adults.
Does the GoodBaby thermometer work for adults?
Yes, the ear and forehead modes work equally well for adults. The thermometer covers the standard body temperature range and provides fast, reliable readings. The large display and simple one-button operation make it suitable for elderly users or anyone who wants a quick check.
How do I switch between Celsius and Fahrenheit?
The GoodBaby allows switching between °C and °F by holding the power/scan button when turning it on. Some users find the process finicky, but it works once you get the hang of it. The current mode is indicated on the display.
