Comments on Alarm Clock for Heavy Sleepers for Android
★★★★★Melissa Markham· Jun 19, 2026
I used to oversleep all the time by turning off my alarm then going back to sleep. The fact that I have to do a math problem to turn it off helps a lot with that. But the real magic is the post alarm confirmation, which *really* makes sure I'm awake! I love this app. It's easy to use, full of great options, and very effective for this heavy sleeper.
★★★★★Amanda Pagett· Apr 30, 2026
So far so good, with clear times for when the alarms go off and a clear interface and one off charge to remove adverts!
★★★★★Man Thianching· Jun 16, 2026
It always wakes me up on time, and it's the best alarm I have so far. So must try or use.
★★★★★Soul· Jun 1, 2026
It's great for getting out of bed because you can't snooze with typing in the letters
★★☆☆☆Alexandre Lopes da Silva· May 28, 2026
Overall, the app is good, but the UX feels like 2000s. It needs a real interface and usability update. And there's no support at all. Don't buy this app, like I did, If you appreciate technical support. If you rely on daily updates that can't be missed, be careful: now and then when you snooze an alarm, instead of ringing again, it gets dismissed.
★★☆☆☆MH E· Apr 29, 2026
Would be a great app but intrusive loud ads make me want to uninstall it and never use it again.
★★☆☆☆WIFIGHOST CRUISER· May 10, 2026
I hope you people know that whenever you solve that math problem which stops the alarm and returns you to your home screen that this app remains active in the background. This is a waste of your battery and there is no need for it to run continuously in the background. It's wasting your battery. It almost seems to be purposely and nefariously running in the background.
