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.

This clock App. is color!!👍🏼👍🏼

I like this app. it’s colorful and is a good clock app. wake-up for the weekends. There no problem’s with this app. and I like changing the colors all the time. 👍🏼👍🏼 This app has beautiful colors every time I use this alarm clock to wake me up. I love changing the colors for my alarm clock and this alarm clock app has never failed me. Just a prefix app. that I truly like and doesn’t need any changes what so ever.👍🏼👍🏼😊 Well I would like to change the alarm clock wake-up on it but, I can’t? Can we fix only that so I can wake-up to a different alarm sound instead of the same alarm theme all the time? Thank you 🙏that all I want! I still like this alarm App..😁
This alarm App is still a great alarm App for waking me up for work. I do have trouble after the alarm wake me up but, it’s not the alarm App fault, it’s mine. I still can’t change the alarm sound to something else but, I’m okay with it. I still like changing the colors all the time 👍🏼👍🏼. Thank you for this wonderful alarm 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.

Leaving after 5 years as a Premium Subscriber

This app has become un reliable all of the sudden. Have been using for about 5 years. I am a heavy sleeper and the last few month the alarms just go off when they feel like it. I use to set a time and the next morning it would go off like it should - Not Any More! For the past three months it’s been a couple times a week the alarm won’t go off. I have 3 different iPads connected to 3 separate jamboxexes of different brands connected via wire or through BlueTooth. Today was the last straw. NONE OF THEM WENT OFF, AGAIN except for my little home alarm clock that just happened to wake me up today. so it’s not just my device having an issue it’s the APP itself. Some just make the notification sound very 10 minutes and not the alarm sound. Some the alarm is up and blasting but only once I hit the home button to figure out why the piece of crap app wouldn’t work only to find that it is working but I had to physically hit the hope button, get into the iPad, and then it’s starts blaring the alarm. I’ve tried resetting my devices every night and it does no good. Also have made sure everything is up to date and no dice there either. I don’t know what you guys have done down there to mess up a beautiful thing but I’m sorry. I’m out. I’m gone and take your piece of trash app with you
