  1. 5/5Very buggy app

    I have used this app on and off for 6 years. WhileI like the unlimited alarms you get, I have written to the developers numerous times about thier bugs and they never respond nor fix them and they are serious bugs. There is a crazy idiotic bug where even if you set it to wake up to music, your music!, it will wake up to whatever sounds it wants. So at 6 am you need to get to work in a foreign hospital but little gentle fairy music comes come on that you did not choose and will NOT wake you up. SO YOU MISS WORK. But you did set your alarm to play loud aggressive music that wakes you up. But it decided not to play it for some crazy reason. The setting to differentiate sounds waking from music does not really exist in the 1st place. The is no clear setting. If you need an alarm that will get you to work and you have a serious job in the military or police Do Not Use this alarm!!!! It will let you down. The developers will not get back to you and they will not explain why there is no setting to turn off sounds. Good luck

  2. 1/5***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.

  3. 2/5App Is just OK. Subscription not OK.

    PRO: I have the free version. Now that I've learned it quirks, the alarm sounds every morning at the desired time. The app basically does what it's supposed to do. CON: (1) The UI and time/alarm display could use some functional and aesthetic updating. (2) There are too many ads, and most are annoying at best and at worst, obnoxious. I was prompted to write this review due to an ad this morning that wouldn't close. I had to kill the app and restart it. (3) I am always willing to pay a few dollars for permanent ownership of an ad-free, fully functional app. I have about a dozen paid apps on my iPhone. However, THERE IS ABSOLUTELY NO WAY I WILL ENTER INTO A SUBSCRIPTION FOR A SMALL APP LIKE THIS that has plenty of alternatives. It's not so much the money; it's the fact that I already have too many subscriptions: magazines, streaming services, software, and news sources such as the NY Times and WaPo. Each one adds to the time and cognitive burden of supervising them: keeping payment methods current, scanning my credit card bill to watch for subscriptions I no longer use. I know that app developers want the steady income from the subscription payment model. However, the devlopers of this app will not get a penny from me unless they allow a one time purchase.

  4. 1/5Ads make alarm clock unreliable

    When I first considered using this app for my alarm clock, I noticed several reviews talking about the ads. Since these reviews were several years old, I thought the developers had that handled. Apparently not. Since I installed the app, I have been rudely awakened on several occasions by loud, obnoxious music from slots ads that played between 1 and 4 in the morning. And then there are the silent ads that don’t self close. I leave the app active on the Home Screen on my iPhone. When an ad appears in the middle of the night, it knocks the alarm app of the the Home Screen and the alarm doesn’t operate like an alarm. This morning is a prime example. The alarm never went off because of an ad that appeared sometime during the night. When I closed down the ad, the alarm app appeared on the Home Screen and showed that it had been waiting for a snooze or stop response for an hour and 20 minutes but the alarm never sounded. This not the first time this has happened. Today was especially irritating because I had an appointment that I didn’t make because the alarm never went off. Most of the time the app works fine. But when these ads show up and interfere with the alarm app’s functionality then it makes the app unreliable. The ads need to self close.

  5. 1/5A must until the last update/upgrade

    The one star is for the current version out there in the past you’ve been a 5. I have used this alarm app for years over the built in Apple one and never had an issue until this morning. Sorry to say the issue forced me to delete the app so I could use my phone. This morning the alarm did go off but muted my phone volume so no alarm. This caused me to sleep in and because the alarm had muted my phone I didn’t hear the calls from my work wondering where I was. When my internal body clock woke me I was already an hour late and could not access my phone because the alarm app was looping and kept setting off the muted alarm. If I came out the app the volume indicator was also looping and showed the phone as muted and a constant notification alert that the alarm was going off. I switched the phone off and when it rebooted went straight into the alarm sounding. Once I entered my password it went straight back into the alarm muted loop. With some difficulty I managed to get the app deleted as all attempts to stop the alarm failed. Let me know when you fix the bug as you have a good product that I’ve used for years with out trouble and I’m willing to give you another chance. Everyone is allowed an error just can’t trust the app until the issue is resolved.
