Downloaded about a week ago the free version and knew that it could clean more. The price is 99 cents so I splurged on it.It cleans a little more deeply and free’s up more memory. I checked the results using the iPhone settings on my phone and it’s pretty much on mark. I only gave 4 stars because I believe that app developers should at least answer peoples questions or at least post a link that takes us to frequently asked questions. I think it would be a top app if they added a CPU cool down and battery check. Otherwise, it’s a decent app and please remember that iPhones older than iPhone 6 will have issues due to Apple requiring apps to uphold privacy on the apps.

Downloaded the app, and though it appears to work, I have no real way of knowing. The total lack of any user instructions is baffling. It tells me to adjust for maximum performance, but I don’t know what per cent to enter. Entering numbers larger than 50% appears to crash the app on latest version of iPad Air. On older iPad Air the app crashing starts about 45%. Why wouldn’t I as the user want performance in the 90% plus range of my device? Please consider inserting a small txt explaining the speed selection or write a routine that determines memory installed and processor and automatically adjust settings for optimum Performance as default.

I’m sure there is others out there that are similar to this app but I found this app about 3 yrs ago and after using it for a few months I made the one time purchase for the Pro Version. It is an extremely easy hassle free way to speed your phones CPU up dramatically. The Pro Version can scan deeper and free up a glitchy or slow to react phone in a matter of seconds. I recommend the pro version but the free version is well worth trying out. Hope additional updates continue to become available. It is literally the most used app on every phone abd iPad in my family.

It seems we don't have all that many apps to choose from, but I will admit it, this for a free app is not bad at all. I have told some of my friends about it and they too have downloaded the app themselves.If your looking for something simple to use, don't look any further, you hit a home run with this app. Normally I'll write my own review, but this is ok for this program.
