The Garmin Jr. mobile application features a daily step challenge where kids can compete with their parents and siblings every day to see who takes the most steps. The daily step challenge resets every day at midnight and can be accessed from Challenges at the bottom of the app and then Daily Steps Challenge. Step totals as well as the date and time of each participants' last data sync will be displayed.

Mutual connections of the family administrator and family guardian in the Garmin Jr. app can be added to Challenges. This can include people such as older siblings, aunts, uncles, other families, etc. Select in the top right and then Add or Remove Participants to see individuals and families that can be added. The family administrator and family guardian can edit their connections by selecting More > Family > Connections.
