WAKE UP ON TIME: Proper Alarm Settings
• Keep the app open and running to always have your alarm go off and play the sounds you’ve set for ‘Music'.
When your app is open, you can use the volume slider within the app. When the app is in the background, use the device volume to set your volume.

• Make sure your battery is charged and to have your notifications turned on before you go to sleep, when the battery level goes below 30% it might not sound. This is due to prevent the device from dying and the alarm not going off.

• Keep your Apple Music available on your device
The music you can select consists of everything you have available on your ‘Apple Music’ app on your device. If the music is saved on your iCloud, and not on the device itself, it won’t be available.

When you closed the app and not having it running in the background? The alarm will use the device volume instead and play the notification sound system.

The app will close itself automatically after 10 hours of inactivity. This is due to prevent the device from dying and the alarm not going off.

When your device is muted, set to ‘Do Not Disturb’ or your device volume is set to 0, the alarm won’t play properly. It will still show the notification without any sound. This is due to Apple’s restrictions as we are unable to access the app settings when the app is closed, only when it’s open or running in the background.

Great Alarm Clock

This has been my alarm clock for several years. I have it on my iPad and it’s very easy to use. I generally push the snooze button several times and I’m glad the snooze button and the off button are very clear. My one issue is that every night I open this app, click off the page asking if I want to upgrade and wait for the ad. I don’t mind the ad, however it takes at least 30 seconds to come up. Which may not seem long, but I’m ready to go to sleep when I put my iPad down, so I place it on my nightstand and wait, and wait, and wait while trying not to fall asleep ( I literally fall asleep the second my head hits my pillow) Most night about 30 seconds later, I have an ad. A lot of nights I think there’s not going to be an ad after all, and I lay down and get settled and the the ad pops up and I have to get back up to turn it off. And about 1 to 2 times a week, I actually don’t get an ad. I don’t mind the ads (and I really don’t mind the nights I get no ads lol), but to have to wait so long for it, is kind of a pain. I understand that this is a first world problem, but I am so tired when I go to bed that I just want to turn my clock on, get the ad, then go to sleep. But other than that, I love this app.

***WARNING: 5 star reviews are old

I like to read reviews and choose things based on highest rating from most people. Unfortunately, I didn’t see that all of the glowing reviews are from previous versions of the app. In the last year they started to change, and I’ve been finding out why.

This morning is the 6th or 7th time that my alarm failed to make any noise and wake me up (I’ve been using the app for several months now). I’m a teacher so more often than not, I keep my ringer on vibrate and don’t bother to switch it on when I’m not at work. It appears that (sometimes?) the app requires the ringer to be on in order for the alarm to sound. Most of the time a little warning message pops up saying that the alarm won’t sound because my phone is muted, so I remember to turn it back on. Sometimes it says that the alarm won’t sound when muted unless the phone is charging. Sometimes it pretends everything is fine until morning when it makes no noise at all. On these days, half the time it indicates that it’d been “going off” for an hour and (I’m presuming) has snoozed itself enough times to just stop trying. The other half it’s like I never set an alarm - no indication anywhere that anything happened at the time my alarm is set for.

It’s heartbreaking because I wanted something that I could customize, and this was perfect! It’s too much of a gamble to be worth it though - alarms need to be consistent, and there’s truly no room for the possibility of it not going off.

Developer Response ,

Thank you for contacting us with this issue, and our apologies for the caused inconvenience. We have received more complaints recently about the alarm not going off, but have not been able to reproduce the problem or pin-point the source of it. Right now we are busy investigating this and gathering data about the problem. If you could assist us in this by giving any information that might be useful in which your alarm went off (was it an overnight alarm, was the screen locked, was the app closed, etc.) then we’d really appreciate it. You can reach us at

Again, our apologies for the caused inconvenience.

Handy free alarm clock app.

New review: I consider this a great free alarm clock app. Very handy travel clock and alarm. Always easy to use. I like that the developers read and respond to feedback. So, for the dev team, here’s what got stuck.
The issue was a promotion for a game popped up (this is a free version so there are ads and offers) but it did not have an “X” to close the ad.
Close the app, reopen and it went to that ad. Kind of frozen. Ironically the game had snow monsters.
Eventually the app cycled ads and the next ad had an “X” and could be closed out.
Old review: Was great; now unusable. Very handy travel clock and alarm. Always easy to use. Recent update for the free version has automatically opened a game (I do not do cellphone gaming.) and gives me no way to exit the game screen except 1. Play the game for free or 2. Exit the app. Have tried three times to find an exit back to the clock without success. Will watch for an update then try again. It is unusable as is.
