LockCal puts your schedule where you already look all day: on your Lock Screen. YOUR AGENDA AS A LIVE ACTIVITY Start your day's agenda with one tap — it stays visible as a card on the Lock Screen. Use the ‹ › buttons to page through the coming days right on the Lock Screen, without unlocking and without opening the app. FIVE DESIGNS Night Sky, Classic, Retro 2010, Minimal or Timeline — pick the layout that matches your Lock Screen. With calendar color dots, locations and a configurable number of events per page. WIDGETS ON TOP Your next events as a Lock Screen widget above or below the clock — plus a Home Screen widget. AUTOMATIC EVERY MORNING With a Shortcuts automation, your agenda starts into the day by itself and can clean itself up at night. YOUR DATA STAYS YOURS LockCal reads your calendar strictly on-device. No servers, no account, no ads, no data collection — the app does not even have internet access.
