I removed a habit from my dashboard—how do I add it back?
If you want to see what those previous goals are and view your stats with them, on Android or the Web tap your profile icon at the top right and choose Archived Goals. Tap on each goal to see your stats and use the Rejoin button to add it back.
On iOS, tap Me and then tap your profile icon at top right. Choose Settings; at the bottom you'll see a link for Archived goals. Tap to view details about the goal and use the "Rejoin" link at the top to add it back to your dashboard.
