garbage. did the little dances they want you to do and watched the ads, ended up watching four before I could actually do anything. then was told if I want to view more than the most recently installed app to backup, I'd need to pay for pro. do you want to know what the most recently installed app found was?? SAI. absolutely ridiculous. I uninstalled it and will never touch this thing again. use zarchiver. it's free.

We're sorry to hear about your experience. Access to older apps in the backup feature is part of the PRO version, while the free version includes core installation functionality. Thank you for trying the app and for sharing your feedback

So I wasn't able to use it because of Secure FRP, but even without allowing install apps from unknown sources it still tried unlike other apps. The only reason it's four and not five stars is because it had a bunch of ads. Anyways I have an idea for this app that you should totally put in. An android emulator. Instead of needing to install the app directly you can just use it through yours. It would be awesome because you would be able to make it so you have to watch an ad for every apk you use.

The amount and frequency of ad's is unbearable! 😵 Also not the original open-source SAI by Aefyr on GitHub. This app source looks if it's "stolen" from that Git user. I get the ad part but not to this insane level! Ease down! Uninstalled.. Will use APKmirror instead. That is also stuffed with ad's, but not as much as this one.
