If you “Stopped” the plan: Unfortunately, no. When you stop a plan, YouVersion removes it from your profile. You will have to start it again. However, if you remember where you left off, you can start a plan as new, then manually check days off as complete.
If you did NOT “Stop” the plan:
1) Home screen: Tap Plans.
2) My tab: Tap the calendar icon next to the plan you want to catch up.
3) Tap the Information icon (the “i” in a circle).
4) Scroll down.
5) Tap Catch Me Up.
