  1. Habana Amos-avatar

    This app is very awesome, it works very well when the phone is running slowly, the app helps and brings the normal speed. it has antivirus that helps me to keep my phone and document,apps, files safely.Actually, it has more for me I appreciate this app, and recomend it to everyone that owns a smartphone to use it and see how it is important. Thank you developers for this.

  2. A Google user-avatar

    I really like this app. It's far better than other "booster/cleaner/coolers" that I've tried. Plus ~ watching the little spaceship take off, is pretty cool, too. 😉. There's a still-frame AD after each completed action, but it's easy as pie to navigate back from, and perform another helpful thing. It also monitors your charging, ... And I believe it helps my phone charge faster, as well!

  3. Good times-avatar

    it's a good app!! you'll really need to make an ad blocker and maybe an Antivirus if you do with it what you did with this app it will be awesone because I'm being played by Google sending me and adjectives takes over the entire phone and does it 20 * in a 30-minute time frame it's made this phone nearly useless because I have to turn the data off to be able to text back and forth with a person. thank you guys.

  4. S Harris-avatar

    I downloaded this years ago on my Galaxy Note and it gradually took up all my memory even though I was careful not to add any features or extra apps. My phone was barely usable, always requiring boosting and cleaning and it would then tell me I was out of memory and the phone overheated yet I had done nothing but apply their apps. The day I deleted it my phone was like new. It's been good for a couple of months now and I say good riddance to useless rubbish.

  5. Eugenr Jacobs-avatar

    Just installed this app so far I like it. So as of now yes I'll give it stars!!!! I very much hope this app continues to perform as it is doing now. But if it starts slowing my tablet down or causes me any types of problems while I'm on any of my apps, I'll uninstall without a problem on my behalf.

  6. Mindy Riddle-avatar

    I did my research looking for a decent cleaner that does not have 1000 pop ups to get to your cell functions. So far this app has cleaned my cell properly. I haven't even had 1 annoying pop up advertisement to clear out to make calls, texts etc.. I'm happy with this app for now. Let's hope it continues being efficient.

  7. Suzanna Barrow-avatar

    it did boost my phone, I give it that. It did so by deleting every single download I had, all my gallery thumbnails so the pics I had became useless tiles, and a few other things it shouldn't touch. Gallery was instead full of ad pictures I'd never seen before. Completely messed up my phone, which is now working again, but still not right. I suggest anything else!

  8. Giuliano Basso-avatar

    Sucks. Even if this app "freeing" memory and clean junk, and close apps which consume battery, this app is nothing. Every process which this app does consumes battery and cpu. Just like clean master and all those app. And about the apps which consume battery, you van close them manually by go to settings and force stop those apps. Useless app.

  9. Daniel Collins-avatar

    its an OK app, but recently I'm starting to see fake "you have a virus" ads after completing tasks. This could easily pose a problem to some not-so-computer-literate users who may see that and think "oh dear, I should hit that button to fix it" and then get hit with some type of virus.

  10. Jade Clarissa-avatar

    Please add a option to remove adds or add option to purchase pro for the removal of adds, I have been forced to stop using this app due to adds, I just want a clean app, no adds just pure application, other than the adds this app is amazing, I write a blog and review alot of apps and games and this is far by the best cleaner app I have used, it offers alot of functions that are extremely useful and they work... also I would like to see a section dedicated to the performance/boosting of games, a feature like that would go very well with what is already available

  11. Wize B-avatar

    Used to be 5 stars, now bloated memory hog! 200MB+ Ram usage!Great graphics but too much silly animation wastes time and RAM to clean and boost! Too many annoying notifications. *Warning* This app heats up your cell a lot=bad! Lastly they broke away Auto features to make you install multiple apps..Good bye. *Make a Lite version please

  12. Babak Lkz-avatar

    It's a very good app and help to protect your device and helps you to use your device better. But unfortunately when I update this app today, my phone started ringing like message ringtone! And I couldn't stop it anyway. So I had to uninstall it. Wish to fix it soon.

  13. joels 66-avatar

    I've used your product for years.. it's always been a good product but now it's getting crazy. you want me to download games to use the product to its fullest potential and also now you have 3 or 4 products with the same capabilities/and the same title and they do the same thing.wow. 5* lol..

  14. Edgardo Rizo-avatar

    not clear what next step after click/tap " move to SD" shall be tapped "force stop"/"uninstall" or nothing to do or clear cache & data / launch...Yet, result was not been moved. Simply, it didn't worked. Aweful!!! but I trust you others. need only to improve & check about it...also too much strictly detect background caused annoying....etc...

  15. Sunil Kumar A-avatar

    Awesome App, You want to Auto stop background Apps in a single click, Save your Battery from draining,Boosting your Ram from sluggish behavior, Clean your phone, Guys look no further here is the Saviour of your Smart Phone. Thank you Developers, For this free app. I have over 300 Apps, Never faced my phone hanging up, memory going low while playing games.

  16. A Google user-avatar

    had this app so many times I keep getting rid of it cause why it says install battery. then install du antivirus then it says too many photos sort them n get rid off some. sorry for you. but I will get rid of photos when it pleases me not you people. I have had many dealing in du apps everyone. but don't you tell me what the hell to get rid of. my mind knows better than what you people can think

  17. Mari Crayne-avatar

    seems to work ok but I DO NOT LIKE the Quiet Notifications tool. It puts apps into the "quiet" section on it's own, even after you've moved it to the "allow" multiple times. I finally had to disable it because I was tired of it quieting apps I want to hear.

  18. Renee Renda-avatar

    This constantly crashed and stopped me from opening apps, receiving , and making phone calls! The adds popped up so much it became virtually impossible to unlock my phone. And it totally dtained my battery at least 20% every time l boosted or cleared my cache'. WHAT A NIGHTMARE!

  19. William Mudd-avatar

    My phone was lagging and freezing and i tried to stay on top of cleaning and maintenance. But it took to much time going to all different locations and settings .... now all i do is hit a button its all done in a few seconds. Love this app great tool

  20. A Google user-avatar

    I have this app for years although I've tried others with the same rating I tend to go back to this app for the fast boost on memory plus trash with my laptop iPhone cell phone and Mac. Has very very few ads and advertisements,and keeps everything running smoothly.

  21. A Google user-avatar

    Best apparatus for cleaning the thrash files, boosting the phone, cleaning the clipboard, effective cooling, anti virus security and boosting the network signals. Most useful Cache Cleaner. I have tested all Apps for such activities but DU is the Best. I recommend this all in one uaeful App for everyone .

  22. Chris Wu-avatar

    This the worst cleaning app I hve ever download it not only doesn't clean the junk in my device but consume a lot of battery in my device. When I look at my application management in my device there still tons of junks that haven't been deleted same go to the network booster its a joke!!! This app is low quality than Clean Master or should I say same as Clean Master cheating on those who download this app!!! I uninstalled this useless app right away never trust this kind of malware app again!!!

  23. Greg LeRoux-avatar

    Once again,the reviews were bogus. Ridiculous amount of intrusive ads, confusing interface which is probably intentional bc they attack you with upgrade offers. You only get 3 services and you have to DOWNLOAD the others. Total scam. Their browser ,(CM) BC they hide their name, also sucks.

  24. Paul William Buniel-avatar

    Paul William Buniel


    very annoying ads! its effective when i used it but when it comes to ads, its very annoying! specially when ur doing something important on your phone, ads automatically appears on the screen. i cant keep with that so i uninstalled it but ads keep on popping up.. so ANNOYING!!!

  25. Elizabeth oluwadipe-avatar

    Elizabeth oluwadipe


    This app is very good, but give the next update feature that will make it rotate to any direction it is bent to, so that if the upper part of the android does not respond to touch, it can be rotated to another direction

  26. Stephen Smith-avatar

    Not sure. Hadn't had ad's til download. Now every time I use my APS. Game's, social media. Everything interrupted with annoying ad's at least every 5 minutes. Or less. Then they either go back to start delete my conversation or back to home screen

  27. A Google user-avatar

    Have tried to download one of its associated apps to keep out unwanted stuff! Unfortunately it stops me answering calls, getting msgs etc. Its a nightmare! chocker with adds. Always end up wiping it & reverting back to just this. 😐

  28. elizabeth hall-avatar

    Had to install another app that actually cleans out my app cache since this one did NOT CLEAN OUT APP CACHE as advertised. I checked my apps before and after using it and it did NOT clean out app cache. This app does other cleaning of junk pretty well, however. Some cache cleaning apps only clean out cache on phones that are Older, or below 6.0 software updates, and this may be one of those. I've now installed a Cache Cleaner that actually Stated that it works on 4.5-7.0 software updated phones

  29. A Google user-avatar

    It is a good app. The only problem is it always tell to either boost or to do cleaning up the phone on something like that so it sometimes irritates. Other ways its a good app. 💯 on 💯 marks from me

  30. Trev T-avatar

    Installed easy enough and from then on it was full page ads after every action. Shame you put so many full page ads, in because l just uninstalled it and wont bother using it again. Plenty of others with less intrusive ads.

  31. A Google user-avatar

    2nd comment. I've used it for a few days now. Bit of a "flashy car" situation with the main face. Ads are needed for it to be a freebie. But it should be available for purchase to eliminate them. Services seem to to do as they describe.

  32. Lavetta Lewis-avatar

    Over the years, I have been using the DU Cleaners, and there was no year at the top of the app icon, and when I received the updated formation of the icon, I refused to use it again, and want it removed before I use it again.

  33. Dakota Genieve-avatar

    Great app ! looked and looked for good cache cleaner as my phone has had issues collecting too much cache etc ... makes it crash freeze you name it. Very satisfied with finally finding a cache cleaner app and more that does what it says. Thanks so much team. Great Job!!!

  34. Mr Stephen Lowe-avatar

    Mr Stephen Lowe


    Excellent all round optimising your device app excellent running app had not many problems at all with the app it is my choice for my android phone cleaner booster,that's why I give it a good old STARS ,,in capital letters

  35. ASMR For fun-avatar

    Addictive and helpful, It entertains me but sometimes it makes false data about some trash that's useless but there isn't. Other than that it's just perfect. Contains ads lol.

  36. A Google user-avatar

    i bought a new android phone and within days had issues id not had with my apple. this app was recommended and has fixed all issues and i now feel my phone is well managed and protected. Thoroughly recommend

  37. Steven Hale-avatar

    Only problem i have with the app is the little on screen icon. It can get in the way sometimes and I'm unsure if there is a way to remove it. The app works though and is great for cleaning trash files and boosting your phone speed.

  38. A Google user-avatar

    I think this app Is very good and suggest everyone uses it. My phone kept running slowly but after I got this app I confidently say my phone is free...but my problem it contains too much ads .

  39. Fran Ossman-avatar

    this app definitely works to boost speed, but i'm not so sure about the cleaning aspect. everytime i go to use the cleaning tool it says i have 1.2 GB of trash and proceeds to "clean" it. i could immediately go back to the tool and it would say i had 1.2 GB of trash. its always there.

  40. Calamity Bane-avatar

    Only one word. Brilliant. My phone is now working faster, cleaner and has a ton more battery than when it was first bought. Just utterly brilliant!

  41. A Google user-avatar

    DU antivirus has been always number one for me. This app is a must. I highly recommend this to anyone looking to make life much easier. Simple easy to use, hassle Free. "KEEP it UP" u DU App clang. Lol

  42. Jesse H-avatar

    If your phone is lagging this will fix it BUT BE WARNED: be very careful about what you delete because it will autonatically delete EVERYTHING including photos. app or game data. music audio and video. and any other downloaded stuff you have.

  43. 100 Nation-avatar

    Most clean apps require the user to go to settings and insist the user to use grant permission on every part of their app. DU speed simply cleans without the irritation dealing with that..great app!!!

  44. LM-avatar

    Works great but was causing black-screen glitch while using the Youtube app. Videos keep playing sound, but image is black. Once the app was uninstalled, the glitch stopped occurring.

  45. A Google user-avatar

    Its the best! It helped me find the file that was making my storage have so little space left! The boost also works well!

    I've been through many cleaning apps in the last couple months & none even begin to compare to this one. It's the best cleaning app for an Android hands down!! Thanks & keep up the good work DU APPS STUDIO!!! 😊😊

  48. Dele Ikeorha-avatar

    Great app. Only problem is size and uninstalls apps in wsys that hurt. I stopped using it for over a year snd sm just trying if its clearing algorithms is still craxy.

  49. bill g-avatar

    I've used this for years, the new update stinks. I keep getting alerts for no reason and my phone won't stop alerting from it. Uninstalling again!!

  50. čžš žčš-avatar

    does not clear cache. cache of the several programs i checked is the same size as it was before cleaning. also the cache cleaner keeps offering me to clean cache no matter how many times i clear it and the cache sizes are always the same.

  51. Nahiyan Syed-avatar

    Nice app but if there was an option to turn off specific notifications and change the color of UI then it would be awesome! Hopefully in the future!

  52. Raja R2k-avatar

    Sometimes, when we touch to security, it done 75% and then it stop the work , and takes too much time. So please repair it , anyway it's amazing app

    Generally good, advanced cleaning found obscure useless filed and released over 400 MB from soft memory (not ram). Ads are not too intrusive.

  54. Michelle Riley-avatar

    Good App for cleaning files and management of them. Doublez up as security checker as well as numerous other tools for boosting ur phone in different areas ....overall a busy wee app that keeps your phone in the check..!!😍 😍 😇

  55. James George-avatar

    An excellent App.... Have been using for years. Neat interface. Will give 5 stars, when 'auto memory clean' option will be available...

  56. Terry martin-avatar

    This app is so lost it has no idea it is installed on a garbage govt. phone, and its scanning my 4 core cpu what a laugh considering it has no cpu at all. It has no idea how much if any ram there is! What a joke! Oops dosen"t know my name either.

  57. aliey 93-avatar

    junk clean likes to remove my homebanking app, I have to push buttons twice or hold longer my thumb on it before something happen, and strange messages are coming from alone. I don't like it .....

    it does help speed your tablet,mainly by shutting unused running programs. also does a good job of cleaning up leftovers.

  84. Logan-avatar

  87. A Google user-avatar

    i have lots of problems with the Apps, once I fixed them it make me redo them I don't know how many times a day.

  88. David Ekwu-avatar

    It's a good app but the ads are annoying and at times it slows down my phone

  89. Sobhan Javi-avatar

    This app is the best one in it's category. but the "speed +" part doesnt work to the end and end the optimizing in the begging... please fix it

  90. A Google user-avatar

    It is one of the best app in the market in its field.It is easy to use.But sometimes tell exaggerated network speed and other informations.

  91. #AS GameR-avatar

    this app is good but it says my ram always above 70 . If i open any bog file like free fire I saw ram 80 but in previous cleaner there was no broblem like this. overall good app😊😊

    I have used this cleaner every time I get a new phone and I've been through my fair share of phones it's consistent so don't fix it if it is not broke.

    There are some ads but they aren't too intrusive. Good app so far. Cautiously optimistic

  97. A Google user-avatar

    Du group of boosters,cleanersand free up space quaity, is unrivalled in the world today.Even this quality is known and envied by other competitors in this game.Actually u have done a great job that attracts a price from guinness book of records.

  98. Ethan Reno-avatar

    Has built in antivirus, as it claims, but has "gift" ads that are very sketchy and Macafee stopped me from viewing them.

  99. A Google user-avatar

    Its a really good app . It helps in managing ones space on your phone. And it also detects phone with virus

  100. john gillen-avatar
