### 3/5 — THE FREE UP MEMORY BUTTON IS MISSING!

*2022-01-21*

I own this app on an older iPad and the best feature is a button that deletes unnecessary cache files to free up badly needed memory. That is the best feature of this app. Rumor has it that Apple forced the developer to delete it. Why? Without the free up memory button this app is only a shadow of what it once was. Come on Apple, let the developer put it back.

### 3/5 — No Process View on iPad

*2019-04-28, version 6.1*

I bought this for the process view and it’s not there 😡

### 2/5 — Crashed

*2019-04-04*

Once the phone is charging, the status is shown fine. But then when the cable is unplugged, the app crashed. It keep crashing until the cable is plugged in again.

### 2/5 — Doesn't work

*2019-04-04, version 6.0*

New updated version doesn't work on iOS 12.
plz fix it asap

### 4/5 — Maj vite

*2018-08-05*

Il faudrait faire une mise à jour rapidement car il semblerait que le programme ne permet plus d’avoir les services proposés.pour ma part, les processus sont totalement indisponible.
Une mise à jour iOS 11 voir 12 serait la bienvenue.

### 3/5 — iPhone 6s

*2017-03-13*

Eu fiz o que o cara explicou no vídeo e no meu aparelho funcionou perfeitamente

### 2/5 — No option to upgrade

*2016-10-20*

The app is a nice app, but is filled with ads.  There is a button to 'upgrade to pro' yet when clicked, the iTunes Store says its not available in the USA store and my region needs to change to Canada.  When I try this, then try the upgrade, the Canada store also says its not available.  Now I have to reset my region due to a broken link in this tool.  I want to purchase the upgrade, if it existed somewhere....

### 1/5 — Don't bother

*2016-09-17, version 5.0*

Old app, doesn't work as advertised!  Ios9 no process list.  Waste of time.

### 1/5 — Nao funciona

*2016-09-02*

Fiz o procedimento cf o video...e nao mudou nada a minha memoria...ficou a mesma coisa...

### 1/5 — Really useless app for me

*2016-05-05, version 5.0*

It does not tell me anything about the two processes that are running or allow me any control over them, it will soon be deleted.

### 1/5 — Running in late mode

*2020-05-26, version 6.1*

Can’t get this utility to run in advanced mode. Comes up with the app in lite mode.

### 1/5 — Apple strikes again?

*2018-11-23*

Even though the sample screen capture for this app shows it can list iOS background processes it can no longer do so. Hence, it is useless for my need to find out what background process seems to go into a race condition that pegs the CPU and RAM. Why does it seem like Apple is so against giving its customers the tools needed to use its products?

### 1/5 — Doesn’t work anymore with IOS 11.x

*2017-10-07*

The RAM free-up utility was really great 
I used this app since 2011 and I’m very disappointed that it doesn’t work anymore with IOS 11.x
Pleeeeeease update ! 😉

### 1/5 — So why didn’t you just updated this so it works on iOS 11 ????

*2017-09-21*

The old version of this app allowed you to close down unneeded memory space so that your device runs more effectively. Why is it that this “upgraded” version doesn’t allow for that anymore? This app isn’t very useful in the practical sense. PLEASE FIX!!!!!

### 1/5 — Junk

*2017-08-16, version 5.0*

I am now running iOS 10 and this app is worthless!

### 1/5 — No

*2017-03-07, version 5.0*

The processes screen lists nothing, but is says 2 on the red circle. It often crashes. And, when I go the the network screen and tap the wifi button, it gives me a blank pop-up.

### 1/5 — Does not work like the old version!

*2017-01-06*

I still have the old version, which has the Refresh button, left of the pie chart, to clean unused stuff out of RAM. 

The new version does not have this feature, although it's shown in the screenshot for the new version. 

The new version is worthless as a tool for me. I still use the old one, but on my new iPhone 7, it barely frees up any memory, and never ceases running the cleanup process.

### 1/5 — Warning: this app does not kill apps

*2016-12-05, version 5.0*

What ever happened to the version which contained the app killer??? Please bring that back.. Apps are not rebooting by just swiping alone! They are remaining stuck. Who wants to spend time deleting apps just to add them back? This version of SYS Has no function at all. When you tap on camera, App Store, anything, you get a blank pop up with the only option to cancel. Heck is that??? This app clearly needs more thought to it to be usable for non savvies and kids.... Thanks

### 1/5 — Con artist developers

*2016-11-17*

You buy and download their app. Then when they update it they don't let you update or upgrade it - they make you buy and download a new version. I did this cycle twice with them, 3rd time at this scam of having to re-buy and download they are out of luck. Apple should remove unethical developers.

### 1/5 — 이거머죠

*2016-11-07*

재설치 했더니 기능 다 사라지고...유료로 구매했었는데...쓸모없는 어플이 되어버렸네

### 5/5 — Assistant

*2021-12-29, version 6.1*

Very good assistant’s

### 5/5 — Desempenho

*2021-02-07*

Funciona perfeitamente

### 5/5 — SYS

*2020-03-09*

This was a really great app in full version, I use to use the full version of the app on every idevice I owed, but seems it’s not available in the full version any more, just the Lite version is available, please update this app back to full version for all idevices,

### 5/5 — Functional & Informative

*2019-06-14*

Has always worked for me, and delivers basic information I want to manage my iPad’s resources.  A good product.

### 5/5 — ;-;

*2019-02-05*

Eu quero saber como faz pra ter mais memória ram

### 5/5 — I love old version (4)--has refresh button.

*2017-05-15*

Version 5 is the lite version and is useless because does not have refresh button to free up memory.  My version 4 is the "pro" version and I use it all the time.  Problem is that Apple says it will no longer work after June.  Please upgrade this app. Please.

### 5/5 — AMAZING APP

*2016-10-04*

My iPod is not really made for looking at the screen all day. It's more for listening to music but I use my iPod touch for everything. I really enjoy this app because it has gotten to a point where my iPod would die after one minute! My father showed me this app and it really works. I just plug in my iPod at night when it's at 20% or lower while the app is running and I wake up and it actually STAYS AT 100%! Great app!⭐️⭐️⭐️⭐️⭐️

### 5/5 — ari-yo

*2016-06-21*

what does the u.s. iTunes app store have against system optimizer apps, system memory refreshing apps, & battery boosting apps? 
seriously! 
every time i find one that does it all, inevitably the app store phases it out. 
these types of utilities are readily available in every other store, but not in the u.s. store.
it's as though apple doesn't want it's customers to be able to enjoy the benefits of this type of utility, and they don't have the right to decide that for their customers.
(and yet they have done just that)
hasn't anyone out there noticed this? 
i cannot be the only person.
