Comments on Good Lock : Custom Lock Screen for Android

★★★★★ dummy · Sep 5, 2026
This app has insane quality. I used every day and this app almostbhas no ad. and no ads are used to the point that it is not inconvenient. I really like this app.
★★★★★ Tobiloba Allison · Apr 17, 2025
I really love it, its was just what I needed, no hiccups or glitches, it works perfectly fine!!! The Wallpapers, homepage, widgets are really one of a kind and amazing!!! This is such a great lock app, and the opening of the lock system is also smooth and not stressful and/or frustrating at all. It's really a great app!!!
★☆☆☆☆ Michael Santangelo · Dec 14, 2024
All I want is a simple and cool looking lock screen, but I don't feel like this app needs contacts, phone, all these extra permissions just to be a lock screen. You can deny it permission, but it will just keep asking. A real shame because the lock screens look amazing. Immediately uninstalled.
★☆☆☆☆ Bryan Verdegem · Jun 26, 2024
Beware, this is not the Samsung Good Lock you're searching for. Its some bogus knockoff. You can only get the real thing through the Samsung store. Save yourself the time and just get the real thing

Description by heyUp (Good Lock) Written by the developer, not by AppBrain. Click to read.
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 you use every day carry no ads; ads appear only on the settings pages.



※ Works on any Android phone, regardless of manufacturer.



✨ Create Your Own Style: Aesthetic Phone Customization

- Download over 1,200 wallpapers for free and combine them with practical widgets to build a one-of-a-kind lock screen theme.

- New high-resolution wallpapers added every week.

- Use your own photos and videos as wallpaper, and style them with a variety of filters.



⚡ Instant Access Without Unlocking

- Clock widget: a wide range of stylish clock designs to match your theme.

- Calendar & schedule widget: see your monthly calendar and upcoming events at a glance, without unlocking.

- Music player widget: play your favorite music and view real-time lyrics directly from the lock screen.

- Quick memo: write down an idea, check an important note, and edit it on the spot.

- Tok Tok shortcuts: double-tap the lock screen to instantly launch a pre-configured favorite app.



🏠 Your Personal Quick Launcher: Mini Home

- Keep your frequent contacts, favorite apps, bookmarks and memos in one place and launch them instantly.
Swipe up from the bottom of the lock screen to open it.



🔒 Lock & Security

- Good Lock has no lock of its own; it uses your phone's lock.

- Memos, calendar and lyrics work without unlocking. You can also browse the apps, bookmarks and contacts in Mini Home without unlocking; your phone's lock (fingerprint, PIN or pattern) appears only when you tap one to open it.



-------------------------------



📜 Since 2015 - An 11-Year Journey as an Independent Lock Screen App

- 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.

- 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.
