Activity unlocks adventure

With you as their helper, your child will unlock new adventures and relive the most exciting moments of the Infinity Saga alongside their favorite Marvel Avengers characters.



Tap challenge game

Not only does 60 minutes of daily activity unlock adventure, the more active minutes kids log, the more chances they’ll get to play the heart-pounding tap challenge game.



Collectible Infinity Stone points

Meeting their daily activity goals also rewards your kid with Infinity Stone points. They can use these points to reveal epic new images of the Avengers.



Fitness cards

Take Captain America’s fitness challenge. Your kids will learn basic exercise moves from fitness training cards, including jumping jacks, downward dog, mountain climbers and more.



Timed activities

New timed activities let kids track their steps and estimated distance during playtime at the park, soccer practice and much more. View saved activities later in the Garmin Jr.™ app.



Color display

Even on bright, sunny days, kids will be able to see everything on the color display. And you can help them customize it with watch faces featuring Captain America, Spider-Man and even more of their favorite Avengers.



ICE (In Case of Emergency) widget

It never hurts to be prepared. Input your child’s emergency contact information into the ICE widget, so it can quickly be accessed if needed.



A helping hand for parents.



Monitor activity

With the Garmin Jr. app, parents can view activity, responsibilities, sleep, chore data and more after syncing with compatible devices.



Chores and rewards

Assign tasks and chores from the app, and designate a reward virtual coin value. Those in-app coins can be redeemed by your kiddos for agreed-upon rewards.



Friendly reminders

When you assign chores and schedule alerts, your kid’s tracker will let them know with an icon that shows what needs to be done. These can be set up to recur weekly or even daily.



Step challenges

With Toe-to-Toe™ step challenges, kids can sync with nearby friends to compete in timed step competitions. Parents can get in on the fun, too, with the Toe-to-Toe app and a compatible Garmin wearable.



Stay active together

Link up with your kid’s friends on the Garmin Connect™ app, and connect with other families in the Garmin Jr. app. Interact with them, and compete in multifamily weekly step challenges.
