Works really well. No issues so far!
works great
love this app so much
i mean it's good if you go to school i guess but im homeschooling
I adore this app! I hate getting up early but life calls for it from time to time& this app totally makes it happen & in the way thats customized to your very own personalized likings...its the best ive seen yet!!!
it's so great it had help me alot so I thank it
it's annoying and that's exactly what I need!!!
my first choice always
works everytime
great app
This app is the only one that will wake me up when I have to get up early. on crazy mode it's the loudest!
Timer feature and Auto snooze can be included
Heavy sleeper? This is for u! My issue isn't so much that I'm a heavy sleeper - as it is, I've just gotten so used to the sound of an alarm that I dont even notice it anymore. So this app is great because it's not the typical alarm sounds. Plus...it switches it up so u dont get used to one sound and accidentally ignore it. This app was exactly what I needed to stop being late for work!!
Was good but seems to have a very bad bug or software issue that makes the same alarm repeatedly go off even once turned off like 4 or 5 times after and won't stop alerting you unless fully deleted out of the app entirely. Goes off at the doc well past the initial alarm. At school etc...very inconvenient now I am deleting it.
this thing is LOUD HOLY MOLY. which is a good thing for an alarm app so 100/10. Recommend to anyone not waking up
Nice Alarm. Helps alot
best app 💯♥️♥️♥️♥️💯💯💯💪💪
cool
It works bro it really works
prwtty cool ans annoying sounds
wakes me up on time unlik my dad
This app is nice !!!
Great alarm. I'm a deep sleeper It gets me up in the mornings. it saves the day
i like it
loud
Great app
well I loved it because of the colors but I've tried to use it a couple different times and the alarm just doesn't work if my phone is on silent mode even with the alarm volume turned up, it will not go off! everything I read online says that it's supposed to still alert you even if in silent mode...this just DOESNT! also I'm coming back to add that it doesn't work when it's not in silent mode either! the only time it works is if I set it a minute before I want it to go off.. makes no sense!
COOL
App work pretty well. Like the loud obnoxious noises

Great 👍
easy to use, great app!!
Love this app, I use it everyday
I purchased the lifetime alarm and it didn't register as purchased. I'm still getting ads and asked if I want to subscribe
it always wakes me up!
One of the only alarms tha5 actually worked for once finally able to myself tf up
insanely loud and Annoying
very easy to use with a lot of different options for alarms
good
undesirable app/rude even to the hearing impaired.
great alarms
very nice app
I am a very deep sleeper. The normal alarms on my phone are never loud enough to wake me up. I used this app for about a year, working very well; progressively getting louder and louder and louder until it wakes me up. Today I slept through it. It got so loud at one point it woke up the whole house DAMN HOUSE and they had to come into my room plugging their ears to turn it off while I was still fast asleep. Works like a freakin' charm. (Ill have you note that my phone was next to my head)
no problems with app. It's been reliable which is what I need because of all my appointments I need to get to.
I woke up👍
15$ just to have "no ringtone restrictions" when tons of free apps have no restrictions at all
The alarm combinations are fantastic and very loud. However, the subscription is pricey and the free app is terrible. When it goes off, an ad pops up that I can't get dismissed. There is no X to close it. I finally get it shut off and somehow on my drive to work it goes off again. There is no way to dismiss that while driving when your phone has a security code. I have to turn the phone volume down until I can stop. Also, there are no snooze options. Idk if the paid version offers them.
Good
Good
without this alarm i would be late every day.
it's very very useful to me
why does my alarm stop ringing on it's own. today I woke up and saw that the alarm was on the screen but it wasn't ringing or vibrating. please tell me how I can fix that
random alarms going off that I never set
it's loud
If you don't buy the premium it won't run every time
works for me ....
works well
this is crazy but good I can easily wake up for this
Your app is 5-star, I'm just putting 2 to let you know that it's not working after latest updates. Besides that, your sounds are the only one that make me get up, thanks for that!
good
app doesn't make a sound when the set time hits. nothing happens
if u wanna be active at any time here is the soln
Best
crazy good is how Id describe it.
works really well that's my review
the alarm works great 👍
Crazy Alarm Clock activates existing alarms at random times. Otherwise this app is excellent.
best one
i love it
wakes me up!
so far so good
This alarm clock is my life saver!! I'm a very heavy sleeper and won't hear an alarm going off rt next to my ear. With this one, I haven't missed one yet. Great sounds, can create your own selection of sounds and the random play option is the best!
Love it.
Wakes me up!!
So good
It's so awesome us it by Downloading. It today
it's a good app
Helps make sure I am not used to my alarm around and it wakes me up everytime, highly recommended for those who travel and had to wake up early.
It's the best
Loud enough to wake the dead!!!
JUMPSCARED THE LIVING SOUL OUT OF ME 🤣 when testing. it Looking forward to using it more
OH YEA!!!
It would've been a good app as it really is effective to wake up someone like me. However, a week of using this app I just cant turn it off and nothing can be done. I can't find the dismiss buttons or snooze. Please fix this for me. Im gonna give it 5 star if its is fix
Good sounds
This is the best thing since sliced bread
Love it 😍
This is the best app for me because it help me wake up p
It helps me
This app is best for set my school when it's streak my cute are broke
It's amazing
It does as it should
It doesn't ring at all
Good
Super
Love it..
I have been looking for a better alarm because I have been late for everything for the past week because the default ones that came on my phone don't wake me up even when I set 8 alarms that are 3 to 8 minutes apart and have them keep repeating. Default ones are to quiet. This app is great. It's amazing how much louder it is. I love the fact that u can pick several tones to go off together which makes it even louder and annoying as hell so I wake up pretty fast now thank God lol 😂.
Well
Very nice app
Great app. It works.
Very good loud alarm.
I love everything about this app Crazy Alarm Clock! I love it, and lots of different alsome sounds, loud, best Clock out there. I give a 5 star 🌟
Awesome!!..this crazy person needs a crazy alarm to wake. And it works for me!
Always wakes me up with ease. I can't live without this alarm. This app puts my mind at ease.
This clock only worked once and every time I set it it would never ring I would not recommend it
This alarm clock app is basically the same as any old alarm app that I've ever seen or used. However, there is one very important difference with this Crazy Alarm app. I have a very hard time waking up to an alarm in the morning, or anytime, for that matter. The reason I like this specific app is because of the alarm sounds to choose from. There are several that are loud and obnoxious enough to actually wake me up. It's as simple as that. Cheers! -Casey-
Crazy alright, this app went off at 4:00am scared the **** out of me. I did not set that alarm. Developer is f***ing with y'all.
You can choose between snooze or close. I chose close and it acts like snooze and the alarm comes back on later. I uninstalled it to shut it off.
Apps been damn near perfect but two days in a row alarms didn't go off well they did but no sound played my volumes were all up and now I got a write up 😭
This alarm will wake me when no other one has!! Definitely recommend!!
Works better than other alarm apps I've used, but the alarm just keeps going off randomly after I close it. A 7:00 alarm is still going off at 8:30 even though I've closed it ever time. Sometimes keeps going off all day
Constantly over sleeping with my other alarm. This one wakes up the dead! Love it!
I can set the alarm but after that the app closes and won't open back
it noisy and I cant hear my old one but this one wakes me up and sometimes my naybor ang I got five bucks cause the noise was waking up a girl next door that was almost late for her opentment so thx sorry I have bad writing cause I'm on pc
i love this app like omg i can wake up early and i can also time my gadgeting and reading
Horrible. Went off in a library, twice. The only time I had set was at 6am and it chose not to go off then but to instead blare at full volume in this quiet library. I'd love to give it no stars but it was pretty loud, I'll give it that.
I am mostly reliant on the app because of it being able to wake up more deep sleepers fairly quickly. Well, this was the second or third time of the app not working. I do not know if it is a phone issue or an app issue, but it made/almost made me late to school and / or work multiple times. I will be un-installing the app, and I will not be re-installing it.
Don't like my default alarm coz it has no access to my own music. Tried several alarms, but they only offer their old outdated sound, Spotify & Google music. Maybe of more than 10 Alarm Apps, this is d only one that match my ideal alarm . Thank you so much developer. If i have to rename this alarm, i would name it - "Perfect Alarm".
Cool loud sounds great for notifications or ringtones!!
Not a bad app, except that it decides to turn on the alarm throughout the day, despite not being set. I then have to watch an ad after dismissing the alarm.
I totally rely on this app in it's Crazy mode. It's one of the few phone apps that actually wakes heavy sleepers like me. Kudos for an incredible design!! Karen C.
They go off on time and are super loud, so it definitely wakes me. Through it does startle me awake. I like that it's random sounds each time because my brain gets used to the sound over time and stops waking to it. My only complaint is how hard it is to dismiss the alarm. I hit ready for the day, and it puts me out of the app and doesn't dismiss alarm. And when I hit dismiss outside of the app, just snooze it . It's very annoying.
Extremely extremely loud. Lots of different alarms
Definately loud. Only alarm that wakes me up.
I have Narcolepsy and I can sleep through ANYTHING!! BUT NOT THIS!! I absolutely LOVE this app!! Thank you for creating this!! It's a MUST have if ur a HEAVY SLEEPER like I am! I even bought the Premium Lifetime package because it WORKED on waking me up. UPDATE: DAMN ALARM DOESN'T GO OFF ANYMORE AT THE TIME I SET IT FOR! BEEN TARDY TO MY JOB TWICE NOW! IF I LOSE MY JOB, IT'S FROM THIS STUPID APP!!! DO NOT INSTALL THIS APP!!! IT IS JUNK!!!
I seem to not wake up by this app the alarm didn't go off on what I set it to be going off by I set it for 8:20 am and 8:30 am and it did not go off fix this issue dev so that I can wake up on time
It's good. It doesn't always alarm on time. Just be sure to have a couple of alarms set just in case one doesn't work.
An alarm that actually wakes me up on the first one! No more setting 10 alarms and hoping one of them actually gets me up!!!
Was not going off when it was set to, however it was going off at random. I once had it start alarming at 2pm one day. I had never set it for that, but it did. That was the final straw, I don't trust my school schedule to this at all
When You can Sleep thru All Your regular Alarms, It's Time to GET Crazy ALARM !!! Pick the Type of Alarm Sound that Works for You!! So Many to Choose From and Right on Your Phone so It's with You All The Time!!! ENJOY!!!
Absolute garbage alarm don't go off until I open my phone 2hours after it was supposed to go off but then it goes off every 20 min all day no way to stop it
This app is great I am waking up on time it's just amazing and you don't have to sign up or anything get this app your love it
Definitely a crazy alarm wakes me up but I haven't used that long, will update soon.
Best alarm there is. Super loud as well.
Love it. Can't say enough about it. It reminds me of a classic alarm clock and I absolutely need that to wake up.
The alarm is super loud and always helps me get up, thank you.
Works as advertised! Cool and different alarms to choose from! 5/5
I am a deep sleeper and tried many one of the only ones to actual wake me up for a long period of time and still does and easy to use.
If you don't wake up to these alarms, you MUST be dead (or you seriously need to have your hearing checked)
I like that it has its own sounds. Other ones I've tried all have the same sounds. I needed nee ones and was happy to find that here!
It's a good alarm but i have a computer so when i shut it does not work .
Best alram. I don't wake up for nothing. Always missed my alarm but this app you have ur alarm so loud it wakes up the dead.
Good app. It fit It's name crazy alarm, it is crazy in fact 😅
Easy to use. Really annoying tones which is a good thing
I love the app so much the alarm is so loud it is good for all havy sleepers.
It gives you many options in terms of your alarm sounds
Badass alarms. You will wake up! And use to stay on point! Helps!
I have not been using this app long, but I am already very Impressed with it, it has all the I want and more besides. I will write a further feedback on r I have got used to it, as I am still finding my way round and gain more experience with it, then I'm sure I will have fun with it, I have already gone Premium which for me this means I'm Confident with the Developer. Give it a go you won't be disappointed with it 😁
Would often bug out and put 6-10 snoozes on its own when snooze wasn't an option on any of the alarms, and then that would happen as an alarm was going, and it would turn off
It actually wakes me up LOL . I sleep through smoke detectors.
Very good alam. It does what it promises to do. SUPER LOUD ALARM CAN WAKE THE DEAD Highly Recommend !!
I'm a deep sleeper and these alarms wake me up... I don't know how to get into the music part on it though
Still not going off when it's set checked for updates no are needed think it's time to find a new app.
The only thing I HATE about this app is when you clear the alarm it still goes off and the ADS ARE RIDICULOUS you can't even shut off the alarm and the ad still plays
Who doesn't love hard to get rid of ads when they first wake up! F this. Looking for a new alarm without ads everytimw the alarm goes off
Worst alarm clock ever. Doesn't go off and all the time when set and sometimes when it does go off it doesn't actually make a sound.
This is a 5 star so far. It is a very loud alarm. It has many sound selections to choose from. Of course it does give you an option to buy a premium service...I didn't. Only because I just need a simple loud alarm to wake me up. I will edit my review and rating in couple months.
This alarm is fantastic! I have used it for a couple of years now, and in all that time, I have never been late due to an alarm not working right. I highly recommend this app to everyone!!!
These alarms will seriously wake you up. Sure, you could turn it off and go back to sleep, but no WAY are you just sleeping through this racket
Very effective!! The only alarm clock that has actually woke me up..
It's a very good app because It is the only app that wakes me up, or other wise I tried many apps but none woke me up this is the app I've been looking for since one month.
Just what I was looking for variety of loud alarms that wakes you up to make sure you won't lay back down 😘😁😁😁👌❤️
It wakes me up when I need it and I can use any ring tone or sound I desire and it has never failed me. What more could I want?
Love this app easy to set, LOUD ,and lots of options!!
Very loud and gets the job done. I have my phone hooked up to some speakers as well. Haven't missed an alarm yet l.
I love it so much it helps me wake up every morning just on time thank you crazy alarm clock app app
Awesome alarm if you have any hearing problems
Volume will not stay up loud enough to hear it.
I downloaded this yesterday bc the alarm on my phone was acting up. I tested this app three times to make sure it would go off and be loud. I have to be at work at 4am so I get up every morning at 2am. Per usual I double check the time set and alarm volume. The alarm didn't go off at all. Unreliable
Very helpful I always wake up late for work,But thanks to this app i don't wake up late very helpful
I'm hard of hearing with extreme hearing loss and this custom alarm that I was able to customize is the only alarm that has been successful in waking me up in decades.... Thank you so much for this app creation that is awesome & the only alarm that wakes me up when I need to wake up @4am & does so in less than a minute
Through Bluetooth , this app works exceptionally well. If this alarm ⏰ can't wake you up then someone may need to call a coroner..
This is awesome❤i love this app really❤❣for sound fir customize and other feature❤❣
Nice & loud, which is what I was looking for. I thought the option of typing a message to stop the alarm would be good to ensure I woke up. Bad idea. Was so drowsy, couldn't make my fingers work. All the while, this LOUD alarm is SCREAMING. I live in a duplex w an old lady. She complains about everything. Here, I'm panicking bc i can't type fast enough to turn this off & I can't think straight bc of the panicking so I don't have her complaining to the landlord!! It works. Just not for me, lol
It's a good alarm clock, it does its job very well. I love its features but the ui is not so good. The premium charges are very high for an alarm clock considering the fact that it lacks appealing elements of ui. Hope to see better ui in future.
Very worst when alarm is ringing The volume button Is Automatically Going Down.
It was good as. I woke up eaisly with the alarms
