Templates are included so you can start quickly, and you can also create your own checklists from scratch. Features - Create and edit checklists - Create from templates - Run a checklist one item at a time - Move items later and optionally save the new order - Choose checklist colors - Sync run state with Apple Watch - Haptic feedback while checking items - Double Tap support on Apple Watch CheckOne Plus CheckOne Plus unlocks every feature with one purchase, including creating multiple checklists, choosing any color, and moving items later.
