Alarmy alarm not going off? 8 causes and fixes

An Alarmy alarm that doesn't go off is almost never a bug in the app. It's iOS doing what iOS does to third-party apps — throttling background activity, muting notifications inside a Focus, or simply not delivering a sound because a permission got flipped. Apple's own Clock is exempt from all of that. Alarmy isn't, and it has to be set up to survive it.

Work down this list in order. It's sorted by how often each one turns out to be the answer.

Quick answer: the usual culprits are Alarmy being force-quit before bed, a Sleep Focus or Do Not Disturb that silences its notifications, notifications or Time Sensitive alerts switched off, low Ringtone and Alerts volume, or Low Power Mode. Fix those, then run a two-minute test alarm with your night settings on.

1. You force-quit the app before bed

Swiping Alarmy out of the app switcher is the single most common cause. Third-party alarms depend on the app being alive in the background to ring continuously and show the mission screen. Once it's killed, at best you get a single notification chime; at worst, nothing.

Fix: open Alarmy before bed and leave it. If you clear your app switcher out of habit, make Alarmy the exception.

2. A Focus is silencing it

Do Not Disturb, Sleep Focus and custom Focus modes silence third-party notifications unless the app is allowed through. Sleep Focus is the sneaky one because it turns itself on every night once you've set a sleep schedule, so Alarmy can work for weeks and then stop the day you configure Sleep in the Health app.

Fix: Settings → Focus → the Focus you use overnight → Apps → add Alarmy to the allowed list. Also allow Time Sensitive Notifications in that Focus. The full breakdown is in does Alarmy work on Do Not Disturb.

3. Notifications got turned off

Settings → Notifications → Alarmy. Check that Allow Notifications is on and that Sounds is enabled. A banner that appears with no sound is what this looks like; tapping "Turn Off" on one notification weeks ago is usually how it happened.

4. Ringtone and Alerts volume is down

Alarm sound from any app follows Ringtone and Alerts volume, not media volume. If "Change with Buttons" is on, pressing volume-down during the day lowers tomorrow's alarm without telling you.

Fix: Settings → Sounds & Haptics → drag Ringtone and Alerts up, and turn Change with Buttons off so it stays there. Seven more volume fixes in iPhone alarm too quiet.

5. Low Power Mode throttled the background

Low Power Mode restricts background activity, and alarm apps that keep a background process to guarantee ringing can be the ones that get cut. If your phone dropped below 20% overnight and auto-enabled Low Power Mode, that's a plausible reason the alarm was quiet or late.

Fix: charge overnight so it never triggers. If you want distance from the phone, move the charger across the room rather than skipping it.

6. Silent mode, depending on your version

Whether Alarmy rings through the silent switch depends on how that version of the app delivers sound. On iOS 26, apps that have adopted Apple's AlarmKit ring through silent mode like Clock does; you'll know because the app asks for a separate alarm permission. If yours hasn't, keep the switch off at night or test it explicitly.

7. The phone was off, dead, or restarting

No app can ring a phone that's off. A battery that died at 3 a.m. takes the alarm with it, and a phone that restarted for an overnight iOS update may not have relaunched the app. Check Settings → General → Software Update if an update landed overnight, and consider turning off automatic overnight installs.

8. It rang — and you dismissed it

The cause nobody wants. A non-repeating alarm that's switched off in the morning means it fired and something stopped it. Alarmy's missions make that harder than a normal alarm, but every mission still happens on the phone in your hand: math gets done on autopilot, shake takes four seconds, photo missions accept anything within reach. People clear them and have no memory of doing so. If this is your pattern, why you turn off alarms in your sleep explains the mechanism — and no settings fix addresses it.

The two-minute test

After any change, test with your real night conditions rather than assuming:

1. Turn on your overnight Focus and flip the silent switch.
2. Set an Alarmy alarm two minutes out.
3. Lock the phone, put it where it sleeps, wait.

Full volume with the mission screen means you're fixed. Banner without sound is cause 3 or 4. Nothing at all is cause 1 or 2.

If the missions have stopped working on you

Alarmy is a good app, and most "not going off" problems are the iOS setup above. But if you've fixed all eight and the honest story is still "it rang and I turned it off," the limit isn't the settings — it's that the off switch is in bed with you.

WakeUpBroo removes it. There's no mission and no dismiss button; the alarm stops only when you type a rotating code from wakeupbroo.com/code, which you open on a laptop or another device across the room. It doesn't test whether you can do a task half-asleep. It tests whether you're standing up. See how it stacks up in Alarmy vs WakeUpBroo.
