dfndr performance: clean, boost, speed & space

Edit 5/18/22 The new ads you all started are horrible! Now when I run Super Economy it jumps to a full screen ad that I have to click off two or three times before I can use any other tools! I won't go through that every time I go to close things on my phone! If you don't fix it I'll go find something else. I love this ap and use multiple times each day!

So far I do like this very much it has been one of the best so far I just wanted to keep using it for a little while to see what it had to offer and I do like this app I will be keeping it. Thank you for keeping my phone safe.WELL I USED IT FOR OVER 4 WEEKS NOW AND I LOVE WHAT IT HAS TO OFFER AND GIVES ME THE CHOICE TO DO SO. THANK YOU %100💜( 5/20/2022) Still here still like this app i'm not use to it yet still learning what all it done or is doing. But i will keep it still for a while longer.

Absolutely the Best Cleaning App plus lot's more.Does everything you need done to keep up your phone in good running condition. Keep up the Great work Guy's you ALL deserve 5⭐⭐⭐⭐⭐Thank You for such a Wonderful App👍

Animated Pop-up ads after using to this product defeat the purpose of cleaning cache and Ram! Go back to picture ads please.

I have been using this app for years, it works very well. It has several features in one.

It's a great app. It has helped me save more battery life and has also helped my phone run smoother. The only thing I noticed is whenever I run Super Economy, it sometimes uninstalls my apps instead of hibernating them... Not sure if that's a problem that can be fixed or not. Edit: The problem got fixed, thanks! Keep up the good work!

My phone has been draining the battery and working horribly for the past few months. It's an older phone but I prefer to save money and invest in my early retirement savings instead of always buying new things. I have been close to giving up and giving in when it comes to my phone. But now I can put it off since running all the optimization tools included. Thanks dfndr performance for a great product!!!

I was a subscriber for almost two years. I loved the app. Since the October update I couldn't use one of the features that was very important to me. The developer got in touch with me right away and their engineering department is working on the issue. The developer was very responsive and resolved my disatisfaction. An excellent app. I am told the update "defect" only happens to certain phones. Go ahead and try this app. It's great. Maybe when they get the kinks out it will work on my phone.

EDIT: 11-8-21: now the super economy doesn't work at all, just puts a blue block on my screen doesn't change anything and I have to close the app to get out of it because it doesn't go away. Sometimes it feels like it doesn't do much but other than that, itll say it cleaned 300 MB of stuff but it doesn't actually in the storage. Pops up ads outside of the app.

Giving an update on this app. I still like it very much, but it is sometimes a little too efficient. Whenever just a few kb of data are taking up space, it wants to clean my phone. Maybe adding a efficient, moderate, and strict mode would be more effective. Also, it barely makes a dent on my battery life, Still a great app, still a 5. Thank you!

Not worth my time. First, I have not seen any performance gains. Tried many of the free features and my Galaxy S7 still performs the same (slow). Second, I can understand seeing ads within the app but being subjected to random pop ups on my phone is ridiculous. I'll be uninstalling as soon as I post this.

It did a very good job when it came to cleaning (cache, junk, etc) however it kept doing an override of my (device) settings, changing things like brightness, shut off/sleep mode & font size (I have vision issues & had them set accordingly) - always had to go back & re-do them & I didn't even have that option enabled in the app, so it shouldn't have been changing them, anyway. Also, experienced a lot of lag & freeze of device with app installed, so ended up removing it.

11/16. App is doing less and less. Pretty clear that it's not working on Note 10 any longer. Promises for over a year and a half that they're working on fixes. Seriously?? I have unsubcribed, deleted app and moved on. 9/30:Advanced Cache Cleaner still not working. As a paying customer, I've been using this app for some time now and was pleased with it completely. However, last year (Fall 2020) the Advanced Clean Cache feature stopped working. I contacted you and was told "it's being worked on".

Great phone cleaner,and security's off the chain!!

This is the best, most efficient and hard working cleaner app. My battery life has improved up to 60%, annoying apps that I have set to not run in the background but they do anyway, get hibernated indefinitely until I reopen them, and this app cleans things most others do not. If perfect existed, this app would be an example of perfection.

Please add full support and app optimization for Android 11. Ever since updating my phone to Android 11, I have noticed a few tools have stopped functioning properly. Specifically it is the quick cleaner, deep cleaner and the advanced cache cleaner tools that have stopped finding as much junk to clean. I have been running all these specific tools for a while now on Android 11 and they have failed to find and clean much junk anymore. This was not the case on Android 10. Fix and I will give *****

Read storage at 45% when settings said 71%, hibernate resulted RAM usage at 14% use any tool after spikes RAM between 51 & 71%. Very shady app, I just can't trust it when accuracy is so far off. Go back to the drawing board and optimize for accuracy and performance. Subscription not worth it unless it unlocks better performance... the fallout 76 of utilities.

Very easy to use. Cleans it up easily and finds stuff I thought I had removed. I like the app security and fingerprint capabilities. RAM cleaner, stopping of background apps, and overall it just works. Just hate the annoying ads but there's a way to rid of them so it's ok. Thanks to you lot my mobile ain't so junky..

Update: this app seems ok now. I found something in settings that needed permission to operate. Now I can actually tell that it's closing background apps. The only thing I wish is that it would close apps in the background without me having to manually run super economy throughout the day. That wound be a feature I'd gladly pay for.

I'm in need of changing my review.The app works just fine but I have one major problem that caused me to uninstall it & maintain my 1* rating The problem is with the ads I know that they pay the bills.I don't mind the full screen picture ads that are easy to close, but when you use full screen live action ads that cannot be closed & prevents me from muting the ridiculously loud audio, your app has to go My search for a better app begins right after I tap the UNINSTALL button. GOODBYE

I don't mind the adds appearing when I'm using the app, but when endless notifications are interupting my work it's very distracting. They cannot be turned off and threaten to interfere with saved work. It's time to delete it and move on. Shame too, I liked it.

Its fast, easy, & get bundle-tasking of all sorts ready, up & going or a quick same-screen-unchechered-box or two to edit the suggested batch to execute "what ever ya do'n...". No need to babysit each & every (ex:) multiple app to put on pause/freeze, (that makes me SO SICK IN OTHER APPS, you check mark a bunch of apps for reason x, clicking "ALLOW & GO", BUT!, you gotta babysit the damn thing through THE WHOLE PROCEDURE, RECLICKING YES. NOT THIS ONE. I can take off to do something as I wait! 😃

I paid for this app to get rid of ads cleaning duplicate pics & cached. But it did not do so well I took a lot of the same pictures to see what it will do it did not clear them and I still had to go in each individual app to clear my cache Plus it always still have ads. Say things kind of pointless to waste your money on.

It's very and very interesting to have this on my phone because I really like the idea of having this app on my phone as well too,But I am grateful that they had made this app to protect and to help them with their problems on how to clean up their phone and how to keep safe from everything else and also from other people who trying to get their hands on there pictures or something like there personal stuff on there phone as well too!

This app is so annoying I don't like how when it goes to blackout or something it goes over my screen sometimes it's okay but sometimes I lose my entire screen that I also pay for a year and got commercials the whole time they never fixed it and you seem like the phone messed up more once I had it or once I downloaded this app

Just recently I got the complete app. It shows results of each recommended task. I just want to make certain that all of these wonderful and positive reports are true!!
