I know people are skeptical about Bluetooth-connected apps for devices that have existed without them for decades, but the Sonicare app is actually really cool. From Shane’s Inventory review:
It’s good then the app is amazing, and changes the toothbrushing game if you actually use it. The Connected app tracks where you’re brushing (and not brushing), how long you brush for, where you’re using too much force, and more. The app will also keep track of when you need to replace brush heads, and your dentist can even use the app to view your brushing data and make notes of where you need to make changes.
In terms of the brush itself, you get basically every feature under the sun—this is the top-of-the-line in the Sonicare family, after all—including that awesome wireless charging cup. Prices vary by color (white is currently the cheapest), but just be sure to clip the $25 coupon to get the deal.
