Good Lock is a custom lock screen app for Android.
Combine aesthetic wallpapers with clock, calendar, schedule, memo and music widgets to build your own lock screen theme, and open apps, bookmarks, memos and contacts straight from the lock screen.
First released on March 15, 2015, Good Lock has been built and run by a single independent developer for 11 years.
Every feature is free, and no account sign-up is required.
The lock screen and Mini Home carry no ads; ads appear only on the settings pages.
※ This app is not affiliated with Samsung Electronics. It is a separate app that only shares a name with Samsung's Good Lock. (Samsung's Good Lock was released in March 2016.)
※ Good Lock works on any Android device regardless of manufacturer - on Galaxy phones and on non-Galaxy phones alike.

📜 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.
- Since another service with the same name arrived in March 2016, Good Lock is sometimes confused with it.
In fact it started a year earlier and has been operating independently the whole time.
- Progress slowed for a while due to budget and resource limits.
Lately I have used the latest AI tools to improve system stability and lock screen UI 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.
