About iProven
iProven began when its founders struggled to get an accurate reading on their own newborns with the ear and forehead thermometers available at the time, and decided to design their own. That original ear-and-forehead thermometer became the DMT-489, still the brand's best-selling product, and the company later expanded into fertility and ovulation tracking (its TTC line of basal body thermometers), blood pressure monitors, pulse oximeters, and personal-care items like light therapy devices. iProven states that its health products are designed to comply with FDA regulations, and every model goes through what the company calls its Family Test: staff take units home and use them in daily life before they're added to the catalog, backed by a 100-day replacement guarantee across the line.
In our own reviews, iProven products earned a place across five separate thermometer categories: basal body, Bluetooth, ear, infrared, and general adult use. The dual-mode DMT-489 and Pro Series models, which switch between tympanic ear and non-contact forehead measurement from a single device by capping or uncapping the probe, stood out in our testing for combining both measurement methods without requiring two separate devices. Its basal body thermometers stood out separately for publishing a genuine 1/100th-degree (0.01°F) resolution, the precision fertility charting requires, at an accessible price. iProven's own materials cite recognition from outlets including Business Insider, Health.com, Tom's Guide, and The New York Times, and our own ear-thermometer review separately notes the DMT-489's real-world validation: more than 18,800 verified Amazon reviews, the deepest review base of any dual-mode ear/forehead thermometer in our lineup.

Measures tympanic ear or non-contact forehead temperature from the same device, with a 1-second reading time at both sites and a 3-color fever alert that gives an immediate green/yellow/red read without checking a chart.

Automatic mode switching means capping the probe activates forehead infrared mode and uncapping it activates tympanic ear mode, with no menus to navigate. Readings take 1 to 3 seconds, a silent vibration alert replaces the audible beep for nighttime use, and a 20-reading memory with color-coded fever indicator covers a two-day fever episode without manual logging.
