Alarm Clock Ultra: The Best Clock App for Your Android Phone

alarm clock appSometimes, the regular clock apps The 10 Best Alarm Clock Apps for Android in 2016 Having a solid alarm clock app is important if you want to wake up on time. Try out one of these. Read More that come with Android just aren’t enough. They’re fine for simple things, and features like Smart Alarm make them decent, but that’s all it can do. In any case, if you’re not happy with the stock alarm clock, there’s only one thing you can do – get a new one.


However, there are plenty of alarm clocks out there, so making the right choice on your first try can be difficult. So what’s the best one out there?

About Alarm Clock Ultra

Alarm Clock Ultra is one of the most comprehensive clock apps on Google Play simply by its large amount of features. The app does come in free and paid versions, but the free version has plenty of features to keep you satisfied. From new alarm sounds to quick sleep alarms for your daily power naps to a little surprise that I’ll reveal a little farther down.


Installation is easy as pie. Simply search for Alarm Clock Ultra in the Google Play Store on your phone, or follow this link in your browser. Hit Install, and you’re already done! Compared to a lot of previous Android apps that I’ve reviewed, this one does not have an iOS counterpart, so those users might have better luck next time!

Getting right into the app, the first thing you’ll see is the clock itself. Besides showing the time, date, and battery level, there are also buttons in the bottom left and top right corners of the clock. The bottom left button lets you adjust the brightness while the top right button turns it into night mode, where the brightness is extremely low but the screen does not turn off, which is perfect for an alarm clock. It’s better if you try it out than me trying to explain it.

The app doesn’t have any menus that are available through the menu button on your phone, but you can navigate the app via the buttons on the very bottom of your screen. The next screen is where you can configure alarms, and there are plenty of settings you can change. Besides the basics, you can choose to play random sounds, gradual alarm increase, length, methods to dismiss and snooze (including puzzles and math), snooze length and maximum limit, math difficulty, and more. In other words, you can tweak just about everything imaginable about your alarm.

The next screen is for your quick sleep alarms, a.k.a. power naps. Here you can simply choose your desired length of 15, 30, 60, or 120 minutes and then hit quick sleep. Your phone will immediately start counting down until it’s time to wake you up again.

In case you don’t like the stock stopwatch or timer, or your phone simply doesn’t have one (it’s happened to me before), then the next screen is all about a stopwatch and timer. These I hopefully don’t have to explain to you, but if you don’t know what they do, just try them out.

As the last little secret goodie, Alarm Clock Ultra also has an egg timer, where you can adjust your preference as well as the size of the egg. The app also displays instructions on what to do so that you get exactly the right egg.

The final screen displays all of the app’s settings. There are some pretty interesting ones too, such as a selection of backgrounds, different icons, shake sensitivity, night mode, vacation mode, and a double tap flashlight setting. This is very useful as well when you can use your phone as a flashlight, directly from the app.

Paid Version

The paid version of Alarm Clock Ultra also contains a few more features, such as social media updates and current weather directly on the clock. They’re pretty cool features to have, but don’t really add functionality to the clock itself.


Alarm Clock Ultra is a really nifty app that can easily be called a “super app” for alarm clocks. I’m surprised that I haven’t discovered this app before, but I’m glad that I have now and I must say that I’m impressed with it. Give it a try and you might say the same!

    Danny, I am addicted to th Alarm Clock Ultra. I came across it several years ago however there is a MAJOR problem with theAlarm Clock Ultra. The app has NOT been updated in several years and has not worked with my last 2 android phones: Galaxy S 7, Galaxy S9 note. I have tried other alarm clock apps but have yet to find any thing that comes close. What can I do? THANKS

    Looks like a winner.

    I've been using Alarm Clock Xtreme, and i'm always open for alternatives.

      Looks pretty cool! But it doesn't seem to be configurable and it doesn't even have alarm functionality!

    i have been using alarm clock extreme and this one seems to have more feautures than it. I see than it has slighly lower rating than alarm clock extreme but i am still going to give it a try.

    I've been using this alarm clock for 2 weeks now and got to say it works like a charm. Love the different settings and the sounds for the alarm are excellent. Started with the free version but quickly upgraded to the paid one. Well worth it.

      Haha I'm considering upgrading as well. Just have to question myself if the extra features are really needed for me. ;)

    This app looks solid, but I'm happy with Gentle Alarm, and I suspect everything is a little closer at hand in the GA interface, from setting quick alarms to making one-time changes to upcoming alarms (skip, +/- 15/30/60 mins) to turning on the "Night Display" bedtime clock (which can also silence your notifications until you dismiss the next alarm). I have it set up on two devices to wake me up gently with nature sounds on my phone and play an emergency alarm on my tablet that also launches Google Reader.

    I am curious about the timer, as I've found all the timer apps for Android cumbersome compared to every dumbphone I ever had. One pro of having a dedicated timer app, though, is that you can set most digital clock widgets to open the timer when you tap the minutes, whereas with any "all in one" app you have to go through a couple layers of menus to get to the actual function.

      Thank you for finding this great android alarm clock app! It has alot of muscle under the hood but most important it reminds me of a fully loaded Battleship. Does it get any better than Alarm Clock Ultra? I used Xtreme,Plus and Gentle Alarm but the last thing I want to do is tell my friends that my alarm that I am using is gentle :)

      The timer seems pretty straightforward to me. In any case, I personally don't have any issues with it.

        Actually, not long after this post there was an item in How To Geek's tips box about the Android timer Ovo. Ovo lacked some functionality (namely, the ability to set a timer for longer than an hour), but it did lead me to a new crop of single-screen, non-ugly, touch-interface timers. I ended up with Doomsday Timer just because I like the old-school green LED look, but HandyTimer and Ovo looked good, too.

    Wooow! Super brilliant review! I appreciate to see that ,this App. Alarm Clock Ultra is actually noticed and appreciated. I am the user of this App and I have to admit, thanks to this app my HTC became fully updated in many functions Alarm Clock :) What a creative developer, has created such a reach in function App. Which provides me full package of amazing function and do not have to jump from one App to another, which I think is troublesome. At night I get live updates feed from my profile on facebook and tweeter sound .... and Sounds Sooter is a hit! always wanted to have these features in my smartphone! It is really great App, meets the requirements of the pickiest App connoisseur !

    It is indeed an ultra app, but I would never use 90% of the features. I use Alarm Clock Extreme (free), which has some very similar features, but doesn't include ones I wouldn't need like stopwatch, timer, flashlight, etc. Alarm Clock Extreme Free has things like puzzle / math problem to snooze, increasing volume, custom alarm sound and so on.

      This is a great review and I must say that I have used this app the last 2 weeks on my HTC One X and I love it. I even Post My Twitter and Facebook from the Alarm Clock itself. It also provides me news from CNN and BBC from any category I want new from. I love it. But the real best feature of this Android Alarm Clock Ultra is? The Ultra Sleep System. This is a built in soother system that allows you to relax and meditate before bedtime and it also has the option to allow you to wake up to them. You cannot compare this app to Any other out there including Alarm Xtreme or Alarm Clock Plus. Xtreme and Plus both have primitive UI and they are truly very ugly to look at. They have done nothing over the years to make it better except to continue fixing the issues. So Now here comes the new kid in town, Alarm Clock Ultra. I love it and I recommend it to all you Alarm Gurus who want the Swiss Army of all Android Alarm Clocks on your Android Phone!

        I need an alarm clock that wakes me up and doesn't take up too many system resources on pointless features. Alarm Clock Xtreme may not look the best, but it gets the job done. If I want to admire something, I'll go look at some amazing scenery photos.

          You must be a developer from Alarm Xtreme.I am a true customer that used your ugly thing for 2 years. Go Back to your application and fix the look so I don't need to wear sunglasses and take immodium while I am looking at that ugly grandmother.What I recommend to you is getting a good graphic artist that can do something to help you and also fix this pandora garbage you have going on. You must be sweating because Alarm Clock Ultra is coming home for Christmas. Get the egg nogg ready Angle Labs! Alarm Clock Ultra is my new destination now.

          Dude, you just wasted a whole lot of words. I'm not the developer, and I'm not associated in any way. Hell, I don't even have the premium version. I am, in fact, a web developer for a small company in south-west England. But believe what you want, I'm done with this conversation.

      • Danny Stieben

        I'd love to try out the Ultra Sleep System if I ever get the Premium version.

      Do you know how well it compares with Alarm Clock Ultra? As ACU has those features as well, I'm curious as to exactly how much more resources it takes up...

      • Scutterman
        June 1, 2012 at 12:05 pm

        I've never used ACU, so I can't offer a direct comparison of resources, but I've never noticed Alarm Clock Xtreme running, and it never seems to slow anything down.
