Update

Said I’d speak when the update came so here I am. Spelling correction made. Good onya. Still a loss of control. I’ll give you one more chance to restore the first version or two versions ago controls….

Useful Ipgrade

I wasn't expecting them to add some
Of these useful tools, plus I like the graphic layout and its focus on the apps that uses the active memory!

Used to work great

Does not work as it used too.

IT WORKS…..

AFTER FURTHER REVIEW I
DECIDED TO CHANGE MY PREVIOUSLY NEGATIVE REVIEW. THE APP DOES WORK VERY WELL.

It used to

Worthless - The new version is not functionally equivalent to the old version. If that’s inaccurate, the developer can list the main functions side by side.

1. Memory Scanner - actively attempted to reclaim RAM, rather than merely displaying RAM statistics.
2. Normal, Deep and Automatic scanning modes.
3. Smart Learning - automatically selected scanner parameters for the particular device.
4. An Advanced Mode allowing the user to configure the scanner manually.
5. Automatic scanning at startup.
6. Options concerning whether inactive memory was counted as free.
7. Disk Scanner in the Pro version, explicitly described by the developer as cleaning “junk / cache files on disk.”

Big Update and Change

This app has definitely evolved. It used to focus on clearing system memory, but since iOS now handles that automatically, it’s shifted into a photo‑ and data‑cleaning tool — and honestly, it does that really well. If you’re looking to tidy up your pictures and streamline your storage, this app is fast, simple, and surprisingly satisfying to use. The feature set is focused, but that’s part of the charm: it does exactly what it promises and does it smoothly. If the price feels right for you, it’s absolutely worth grabbing.

Where’s my useful system tool gone?

This is not the same. It’s useless

Υπέροχο!

Πολυ καλό!

Free RAM no more!

I paid for this app many years ago because of the ability to free up/clear RAM and now its just useless to ke and anyone else who used it for that. Such a shame on a good app.

garbage purchase for ram cleaner only

update changes what i purchased to don’t want or need …

Not good, no value

Doesn’t clean memory, photo cache or anything else.

Response from developer

Hi, the Pro version has just been updated to the latest version as well. It will be updated automatically through the App Store, or you can update it manually from the App Store if needed.

Stopped Working iPhone 17Plus

Mine stopped working this last year.

Crashes

This app crashes with every settings combination on an iPhone 17 pro max. This was and may still be a good app on older phones. It needs work on new ones.

Works, sort of

On an iPhone 17 Pro Max, it crashes constantly while running a memory scan.

ชอบมาก

อัพเดทบ่อยๆหน่อยคับ แต่รวมๆคือดี

N’ARRÊTE PAS DE PLANTER Applications close automatically, it's annoying

Depuis la dernière mise à jour iOS 26.4.1 l’application, n’arrête pas de planter en se fermant automatiquement quoi que l’on fasse.
Pourriez-Vous mettre à jour votre application s’il vous plaît.
Bien cordialement.
Rivkah.

Since the last iOS 26.4.1 update, the application does not stop crashing by closing automatically no matter what you do.
Could you update your application please.
Sincerely.
Rivkah

Needs an update for new iPhone models, 17 Pro Max.

It's been crashing all the time.

IPAD-Pro 2025 kein RAM SCAN

Nutze den Vorgänger schon seit vielen Jahren für iPhones und iPads. Seit iPhone16 Pro Max stürzt der RAM SCAN ab. Mit dieser neuen Version habe ich gehofft, daß diese Problem behoben sei! Leider tritt es hier auch wieder auf.

Help!

How do I adjust the settings to make it stop crashing? I haven't been able to use it at all.
