No. This app (good-lock.net) is an independent lock screen app run by an individual developer since March 2015, unrelated to Samsung Electronics. Samsung's Good Lock is a suite of Galaxy-only customization modules launched in March 2016.
This app (good-lock.net) launched on March 15, 2015, about a year before Samsung's Good Lock, which launched on March 30, 2016.
No. Samsung's Good Lock is a suite of modules that changes the whole Galaxy phone UI. This app is a cover that lays over your existing lock screen and deals with the lock screen only. You customize the lock screen with wallpapers and widgets, and open apps, bookmarks, memos and contacts right from it. They share a name, but their direction is entirely different, so the two are hard to compare on the same terms.
No. Samsung's Good Lock is a system-level tool that changes the whole Galaxy UI. This app only displays a screen over the lock screen; apart from the "Display over other apps" permission it has no ability to change the system. Your existing fingerprint, PIN or pattern lock keeps working exactly as before.
Yes. This app (good-lock.net) works on any Android device regardless of manufacturer. Samsung's Good Lock only works on Galaxy devices.
If your goal is to customize the lock screen, yes - it is a solid alternative. You can install it without any device restriction, and it gives you wallpapers and widgets to build your own lock screen. It does not change the wider Galaxy UI, though, so it does not stand in for Samsung's other modules.
Yes. They are separate apps, so installing both causes no conflict. Samsung's Good Lock customizes the Galaxy lock screen itself, while this app shows its own cover screen on top of it.
