SD Maid 1 Pro - Unlocker

★★★★★ Used it to keep an old phone alive longer, perfect to the point of necessary for cleaning up dead files that deleted apps can leave on your phone. Had this app for what feels like 10 years and haven't regretted the pro ever.

★★★★★ This app rules! Well two apps, actually. You have to get the pro version it's only a one-time payment of three or four dollars. Don't let the 1990s UI fool you. It took me two months to figure out. I Had to learn how to use GitHub and register as an Android developer just to learn the terminology used. I would get these apps now because knowing Google they will probably put restrictions on the accessibility API soon and screw up more apps that used to be good, like "Malware bytes".

★★★★★ Already paid for premium, great app. Hopefully this one doesn't shut down, and I'm maid to pay for premium after one year for the new one coming out.

★★☆☆☆ I don't understand that if you are going to create a new app for newer Android version, why not just update the current app with new features?! Already paid for this version, and it was working fine. With new app, you disabled the app cleaner feature in this app and I now have to buy the other app pro version. At least allow the pro version users to use it.

★★☆☆☆ Totally waste of money. Now it doesn't clear the cache of apps for that you have to buy new app of sd maid that doesn't make sense I already paid, and you are asking to pay again for the same features.
