Prime Day is making it much easier to pick up a Fitbit without spending more than you want. Both the Fitbit Charge 6 and Fitbit Ace LTE are on steep discounts today. Right now, you can buy the Charge 6 for $85.45 ($74.5 off) at Amazon, while the kid-friendly Fitbit Ace LTE is $69.99 (a whopping $110 off).

The Fitbit Charge 6 is a great fitness tracker that combines a wide range of health and wellness features with some useful smartwatch perks. As someone who uses the Charge 6 every day, I especially appreciate its reliability and fast charging. I’ve also found the band stays securely fastened throughout the day, something I couldn’t say about the budget-friendly fitness tracker it replaced.

In addition to monitoring activity, sleep, blood oxygen levels, and heart rate, it features an FDA-cleared EKG reader, a feature that’s uncommon on fitness trackers even at the Charge 6’s regular price. Fitbit also upgraded the device with the ability to broadcast your heart rate to compatible gym equipment via Bluetooth, along with a new haptic side button that’s easier to use than the touch-sensitive controls found on earlier models. Other highlights include built-in GPS and turn-by-turn navigation through Google Maps, including support for driving directions. It also support contactless payments from your wrist using Google Wallet, and supports YouTube Music controls.

If you’re shopping for a child, the Fitbit Ace LTE is designed to get kids moving while giving parents added peace of mind. The smartwatch combines activity tracking with movement-based games that reward kids for being active. It also offers built-in LTE connectivity, location sharing, calling, and texting through Fitbit’s $9.99-per-month Ace Pass subscription. Using the Fitbit Ace app, parents can manage who their child can contact and view their location, allowing kids to communicate and share their whereabouts without using a smartphone.
