MustDo: To-Do Alarm

"I'll do it later." Later never came. The notification came and went while your phone was face down on the table. MustDo is for the things you cannot let slide. Add a to-do and a time. At that time, a real alarm rings and keeps ringing until you stop it. Stopping it means you did it. Not yet? Snooze until you do. ■ A real alarm, not a notification MustDo uses AlarmKit, the same system behind the Clock app's alarms. It rings full screen. It rings through Silent mode and Focus. It keeps ringing until you reach over and stop it. A notification you can swipe away is not a reminder. ■ Stop it when it's done Stopping the alarm marks the to-do as done, and it moves to Completed in the Today tab. Tapped Done by mistake? Swipe left to undo. ■ Not yet? Snooze until you do it "10 min", "1 hour" and "Tomorrow" are right on the alarm screen and in the Live Activity on the Lock Screen. It comes back and rings again, as many times as it takes. Tomorrow rings at the same time, or at a fixed morning time if you set one. ■ Repeats Daily, or weekly on the days you pick. The medicine at 9 PM, the bins on Tuesday, the report every Friday. Snoozing a repeating to-do to Tomorrow skips today's occurrence only. ■ Your to-dos stay in your iCloud Everything is stored in your own iCloud (CloudKit private database) and synced across your devices by Apple. MustDo has no server that stores your to-dos. No account, no sign-in. ■ Add with Siri and Shortcuts Say “Add a to-do in MustDo” to Siri and it's saved with an alarm set, without opening the app. Ask for “Today's to-dos in MustDo” to hear what's left. Also works from the Action button and the Shortcuts app. ■ Add to-dos from AI (MCP) A small MCP server for your Mac lets Claude and other AI clients read and add your to-dos, straight into your iCloud. Tell your assistant what needs doing; MustDo rings until it's done. ■ Make it yours 25 alarm sounds, or vibrate only. Light, dark, or match your device. Optional Face ID lock: alarms still ring and can be stopped while the app is locked. ■ Free for 30 days, then a subscription Try everything for 30 days. After that, a subscription (monthly or yearly, auto-renewing) is needed to add new to-dos. To-dos you have already added keep ringing without one, and you can still stop, snooze and delete them. An app like this should never go quiet because of billing. Requires iOS 26 or later.
