Workout, rest, repeat. Focus, break, repeat. Timers runs multiple timers automatically in sequence. Save them as a group, set how many times to repeat, and reuse your routine. Core features are free; ad removal is a one-time purchase. ■ Run timers in sequence Combine intervals such as 20 seconds of exercise and 10 seconds of rest, or 25 minutes of focus and a 5-minute break. Set a repeat count for each group. ■ Save your everyday routines Reuse groups for studying, workouts, stretching, or cooking. Templates and duplication help you set up another routine without starting from scratch. ■ Notifications, speech, and countdowns While the app is open, sounds, speech, and countdowns help you follow your routine. In the background or with the screen locked, notifications alert you. Notifications must be enabled in your device settings. Notification sounds depend on your device settings. ■ Make it your own Set durations, names, repeat counts, and sounds. Advance notices, auto-lock control, active timer badges, and Dark Mode are also available. ■ Remove ads with a one-time purchase Core features are free. Premium removes ads with a single purchase, not a subscription. Restore your purchase using the Apple Account you used to buy it. Keep your daily routine together, one group at a time.
MustDo

"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 servers of its own. No account, no sign-in. We never see your to-dos. ■ 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.

Verdict
The clearest difference is ads: MustDo at none against Timers's shown. Timers's advantage is iOS requirement (17.6 vs 26.0). On price, in-app purchases and device support there is nothing between them.
