Build step-by-step alarm routines that actually ring. Alarm Stacks lets you create stacks like Wake β†’ Hydrate β†’ Stretch β†’ Shower β†’ Leave. The first step can be Start in (a countdown) or Fixed time; later steps can be Fixed time or After previous. Alarms use the system’s full-screen interface and ring even with Silent or Focus enabled. Follow along on the Lock Screen with a Live Activity, skip or snooze a step, or control stacks with Siri and Shortcuts. Highlights β€’ Real alarms β€” System-grade ringing that works even with Silent/Focus on.
