Good Lock : Custom Lock Screen

Good Lock is a free lock screen app you can use on any Android phone in place of the default lock screen.
Combine aesthetic wallpapers with clock, calendar, schedule and music widgets to build your own lock screen theme, and use your schedule, memos and music right away, without unlocking.

Unlock Good Lock and go straight to the fingerprint, PIN or pattern set on your phone - no stop at the default lock screen.
Your phone's own lock stays in place, so it's safe to use.

First released on March 15, 2015, Good Lock has been built and run by a single independent developer for 11 years.
No account sign-up is required.
The lock screen and Mini Home carry no ads; ads appear only on the settings pages.


※ Not affiliated with Samsung Electronics. This app only shares a name with Samsung's Good Lock (released in March 2016).

※ Works on Galaxy and non-Galaxy phones alike, regardless of manufacturer.

📜 Since 2015 - An 11-Year Journey as the Original Independent Good Lock

- You may see it written as Good Lock, GoodLock or Goodlock.
The official name is "Good Lock" - a blend of "Good" and "lock screen".
Your phone starts at the lock screen, so the name also wishes you good luck each day.

- Often confused with a same-name service from March 2016, Good Lock started a year earlier and has always run independently.

- Progress slowed for a while due to limited resources; lately I have used the latest AI tools to improve stability and performance myself.

- There is no flashy marketing here - just a lone developer's persistence.
Leave your thoughts in a review and I will reflect them in the next update. Thank you.
