Is this Good app lock for Samsung M31?

[MShafiq023]

I have installed App lock, but the app lock of Do mobile consumes much battery due to adds and every time when you open locked app, it shows adds, its very annoying. So that I uninstalled the app lock app. I searched a lot to find a good app lock withut adds but did not find any, I have read somewhere on this forum about good lock app. I like to know that good lock app by Vora Harsh Kumar is good app and trustable. Please guide . Thanks

Samsung's official good lock app is a customisation app, not app locker. Don't get confused with the name "good lock".
