However the app crashes throughout the day which gives very annoying notifications. As far as I can tell there’s no way to turn off these crash reports without turning off all app notifications. Needs to be fixed or I won’t be paying for the premium version! ### 3/5 — GLITCHES ARE OBNOXIOUS *2026-01-15, version 7.2.4* An alarm will go off. I will hit “stop” then 1 minute later it will annoyingly start ringing again. I did NOT snooze it, I’ll shut it off and it will still go off 1-2 more times. Now it will just freeze the whole phone, continue ringing and not let you snooze it. This app had potential, but the glitches aren’t getting better they’re getting worse…. I will be forced to permanently delete it soon if these aren’t fixed. ### 3/5 — Alarm clock *2025-12-01* Great clock but uses half my battery! Went down 50% in 5 hours! ### 3/5 — Ok, I’m up! *2025-11-20* I often sleep with an earbud and some sleepy stories. I needed to get up really early and so wanted an alarm that would work through my earbuds. Other alarm apps would not play through my earbuds and I couldn’t risk being late again. It got me up, but I couldn’t shut off the alarm. It just told me to keep moving! I did not want my travails to wake my husband as well. I finally had to reboot my phone and delete the app to get it to stop. So, it worked, played through my earbuds - and sent me into a panicked state on an important morning. ### 2/5 — no alarm sound *2025-10-27, version 7.2.4* the alarm never actually goes off for me. it’s always just the backup buzzing which doesn’t wake me up. now i set it for two minutes after a regular alarm to help me get out of bed and that helps, but it would be nice if it worked as intended. ### 2/5 — Keeps crashing *2025-10-18, version 7.2.4* Works okay (although the camera takes a second to load up if you’re using the barcode scanner), BUT I keep getting notifications saying “crash notification” that are starting to get annoying ### 3/5 — Please Fix the Glitches *2025-09-26, version 7.2.4* An alarm will go off. I will hit “stop” then 1 minute later it will annoyingly start ringing again. I did NOT snooze it, I’ll shut it off and it will still go off 1-2 more times. IT’S SO ANNOYING. I like your app, but I’m going to be forced to delete it if this keeps happening. Can you please fix it? Thank you. ### 3/5 — Poor execution *2025-09-22* I just woke up with the alarm for my first time and it kept telling me to scan “the barcode” and I went to my bathroom and scanned every barcode, including my toothpaste, and none of them worked so I had to just delete the app to get the alarm to stop. Also, it did not break through my do not disturb mode and there were no instructions to get it to do so. ### 2/5 — keeps crashing *2025-08-15, version 7.2.4* i like this app, but it crashes like. twice a day. the backup ringtone is very quiet and i sleep through it.. ### 3/5 — Great alarm but *2025-08-01, version 7.2.4* This is a great app. The alarms are loud and annoying just like they should be but you have to keep the app open or it spams your phone with notifications every hour until your phone explodes ### 4/5 — Awesome App *2025-04-28, version 7.2.4* I love this app overall and i use it everyday. I used to fall asleep through my alarms, and the missions here helped me wake up, since the alarms are loud. Would recommend, and has a lot of features. Only no ads is slightly expensive and sometimes the alarm bugs and delays. ### 5/5 — Life changing! *2025-04-14, version 7.2.4* Nothing else has been able to get me out of bed. I’ve tried everything. The scanning feature to make you get into your bathroom is genius ### 5/5 — Like it *2025-03-11, version 7.2.4* Helps me wake up but there does need to be a different version, I routinely delete the app on weekends cuz I forget to turn the alarm off. ## Most critical reviews (10 lowest-rated) ### 1/5 — Oh my gosh *2026-05-15, version 7.2.4* I tested this, and everyone in my house started yelling at me. This sound was horrendous, worst sound I ever heard. ### 1/5 — crashes like every two secs or smth *2026-05-08* yeah ### 1/5 — Why am I being women up in the middle of the night *2026-01-16* I’m too tired for this I did NOT set an alarm for 9pm I need to wake up early tomorrow not be woken up with blue screen when I’m trying to fall asleep ### 1/5 — Extreme price hike, no updates *2025-11-30* Well, I gave 4 Stars when the Ad Free Version was about 5 € (and I bought it). But now with no Updates since 1 year it's suddenly 29,99€. Can not recommend this any longer. ### 1/5 — Doesn’t work!! :( *2025-05-17, version 7.2.4* How disappointing. I had an alarm like this years ago and it was a GEM but the developer scrapped it. Here I am, absolutely NEEDING to wake up at an odd hour and downloaded this is good faith. I even tested it before falling asleep. Great. I woke up an hour late with dozens of silent notifications on my screen. Yes, my sound was on and all the way up. So, if you absolutely need to wake up, skip this app and find a different one. Thanks to this app for ruining the day. 👍🏻 ### 1/5 — I hate math *2025-05-17, version 7.2.4* Especially if it’s not optional ### 1/5 — Great when it works *2025-03-07, version 7.2.4* This app is wonderful for waking you up and getting the morning going. That is, when it doesn’t crash which is every single day since the first three days I had it. Off to find a better one. ### 1/5 — Awful *2024-12-18, version 7.2.4* That was like a bad practical joke trying this app for the first time. A never ending string of questions while making annoying sounds is a terrible demo. Immediately uninstalled. ### 1/5 — Crashes daily *2024-03-20, version 7.2.2* This is garbage. Don’t rely on it to wake you up. It crashes almost every time I use it. When it crashes, be prepared to go through every single alarm that it missed, one after the other. I wish it worked. ### 1/5 — Crashed the first night *2023-10-03, version 7.2.2* I was very excited about this app and it crashed the first time using it, I over slept and hour and a half. I will not be using it again. ## Most praised reviews (10 highest-rated) ### 5/5 — Love it! *2026-03-29, version 7.2.4* Love this alarm I’m a heavy sleeper been late to work and sleeping thru alarm but not with this alarm app love the shaking phone mission to make sure I’m awake. ### 5/5 — Great! *2026-01-30, version 7.2.4* Has a nice loud alarm that actually wakes me up and makes me use my brain so I don't go back to sleep ### 5/5 — It works *2026-01-17* I have a smart watch that tracks my sleep. I was looking at my sleep consistency bar charr for the last 30 days today and i was pleasantly surprised to that there is a clear distinction in the data from before i used the app to after. My wake-up time has been the exact same every day since i started using this app. It forces you out of bed. ### 5/5 — Pisses me off every morning 10/10 *2025-12-24, version 7.2.4* Does exactly as intended ### 5/5 — slay slay slay *2025-12-23, version 7.2.4* i literally have the WORST time waking up, i’m just literally the worst morning person ever and my bed is so comfy but this gets me UP!!!! ### 5/5 — Worst alarm *2025-10-12* It’s so loud. It’s unbelievable loud and it never stops it has literally haunted my dreams making me wake up in a cold sweat. It wakes me up tho I wish there was a way to prevent me from deleting it since I’ll occasionally do that then go back to sleep. Perfect otherwise I hate you :D ### 5/5 — I HATE / LOVE this alarm *2025-09-22* I’ve tried every alarm there is. The dumb bell, the one that rolls off your bedside table, the photo match one and none have worked as it’s easy to stop the alarm and go back to sleep or just turn your phone off. The sound this alarm makes is so horrible that I wake up BEFORE it goes off just so I don’t have to listen to it!! ### 5/5 — Love *2025-09-10, version 7.2.4* Great stuff ### 5/5 — I never review apps but this one is life changing *2025-06-24* There were bugs before so I use my phone alarm as a backup, but I think the new update is supposed to fix this. Otherwise, the functions of the app and ALL the features are perfect for helping me get up despite hating it. I highly recommend ordering the missions like this to help wake up more smoothly: phone shake (can do with eyes closed and help get blood flowing), color memory, math, then barcode to make sure you get out of bed. ### 5/5 — This is my plan c *2025-04-18* I usually sleep through my 15-20 phone alarms, and I always set this one as my last line of defense. It is nearly impossible to sleep through and the challenges help me get out of bed ( mainly as a result of pure rage). I feel like aliens are abducting me every morning. Sometimes I can’t get the math questions right and I just delete the app to get it to stop. Even then it still works though. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
