The lock screen and Mini Home carry no ads; ads appear only on the settings pages.

📜 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.
