The Android 17 canary is testing more lock screen clock options than any Android release has ever shipped, and the community has already found what’s missing: real font control, actual layout freedom, and always-on customization for phones where Google hasn’t blessed the OEM. Every Pixel, Samsung, OnePlus, and Xiaomi flagship still ships with a clock face picker that feels like a placeholder next to what iOS did in 2022.
If you want a lock screen clock that matches your wallpaper, shows the info you actually care about, or just picks a font that isn’t Google Sans, you need a third-party app. We tested every popular option on Android 14, 15, and the 17 canary. Here are the ones worth installing.
What to look for in a lock screen clock app
The market splits into two camps: full lock screen replacements (fewer than you’d think work well on modern Android) and clock widget/overlay apps that layer on top of Google’s stock screen. When picking, look at:
- How it renders on always-on display. Some apps stop drawing when the AMOLED goes low-power, which defeats the purpose on flagship hardware.
- Font and layout control. The default clock face pickers give you maybe five faces. Real customization needs a template editor.
- Weather, calendar, and battery hooks. A good clock widget shows the next appointment and the current temperature without waking the screen.
- Battery draw. Anything animated pulls power. Static designs cost almost nothing.
- How it handles OEM lock screens. Samsung One UI, Xiaomi HyperOS, and OnePlus OxygenOS each override differently. Test on your specific phone.
- Permission surface. Any app asking for accessibility service, notification listener, and device admin to render a clock is doing something it shouldn’t.

The apps
1. KLCK Kustom Lock Screen Maker — Best for full custom lock screens
KLCK is the tool people build actual lock screen designs in. The template editor lets you place clocks, weather, calendar events, images, and animated elements anywhere on the screen. The community preset library (via /r/kustom on Reddit) has thousands of user-made designs you can import in seconds.
Where it falls short: The learning curve is steep. If you want a “pick a face, done” experience, KLCK will overwhelm you. Also: on Android 12 and later, KLCK requires the phone to boot into a specific accessibility mode to fully replace the lock screen, which limits use on some OEMs.
Pricing:
- Free: All features with a small watermark
- Paid: $4.49 one-time Pro purchase removes the watermark
Platforms: Android 8+
Download: KLCK on Aptoide · Google Play
Bottom line: The right pick for anyone who wants to build the lock screen rather than pick one.
2. Chronus Information Widgets — Best for clock plus weather
Chronus is a widget-first app, not a lock screen replacement. Add a Chronus clock widget to your always-on display and it shows time, date, weather, next calendar event, and battery in a clean typographic layout. The widget skins cover DIGital, analog, and text-only styles.
Where it falls short: Not a full lock screen replacement. You still get Google’s default screen underneath.
Pricing:
- Free: Full functionality with occasional upgrade prompts
- Paid: $2.99 Premium removes prompts and unlocks extra widget skins
Platforms: Android 7+
Download: Chronus on Aptoide · Google Play
Bottom line: The pick for people who like their stock lock screen and just want a better clock plus weather widget on it.
3. Always On AMOLED — Best AMOLED always-on display
Always On AMOLED replaces the standard always-on display with a customizable clock, notification icons, and battery meter. On OLED phones without an official AOD (many mid-range Android phones), this app fills the gap. On phones that do have AOD, it gives you options the OEM hides.
Where it falls short: Uses the accessibility service to keep the screen alive, which some users won’t want to grant. Battery drain is higher than a native OEM always-on because the software has to work around Android’s power management.
Pricing:
- Free: Full features with occasional ads
- Paid: $3.99 one-time Premium removes ads and unlocks extra clock styles
Platforms: Android 6+
Download: Always On AMOLED on Aptoide · Google Play
Bottom line: Install on OLED phones without a native always-on display.
4. AlwaysOnEdge — Best for Samsung Edge displays
AlwaysOnEdge is a specialty pick. It replaces Samsung’s Edge Lighting and Always On Display panels with a clock design that respects the curved edges instead of ignoring them. The lock screen edge glow can be color-coded by notification source, so you can tell a text from an email without waking the phone.
Where it falls short: Only useful on Samsung Edge devices. Newer Galaxy phones with flat displays get nothing out of this.
Pricing:
- Free: Full features with ads
- Paid: $3.49 Premium removes ads
Platforms: Samsung Edge devices, Android 7+
Download: AlwaysOnEdge on Aptoide · Google Play
Bottom line: Galaxy Edge owners who miss the curved-display era should install this.
5. Fitness Watch Face — Best for watch-face style clocks
Fitness Watch Face puts a smartwatch-style face on the always-on display. Analog hands, digital sub-dials, step count, heart rate readout (when a Wear OS or Fitbit watch is paired), and battery. It’s the pick for people who like the look of a Garmin or Apple Watch face on their phone screen.
Where it falls short: The watch face aesthetic isn’t for everyone. Some faces feel busy on a phone-sized screen.
Pricing:
- Free: Basic faces with ads
- Paid: $2.99 Pro unlocks the full face library
Platforms: Android 8+
Download: Fitness Watch Face on Aptoide
Bottom line: The lock screen equivalent of picking a favorite watch face.
6. DashClock Widget — Best info-dense clock widget
DashClock is the old-school open-source clock widget that’s still one of the cleanest info-dense options. Extensions add gmail counts, calendar events, weather, missed calls, and battery in a strict typographic hierarchy. It’s minimalist by design.
Where it falls short: Development is community-maintained. Some extensions have gone stale. The widget looks its age on curved and cutout displays.
Pricing:
- Free: Fully free, open-source (Apache 2.0)
Platforms: Android 8+
Download: DashClock on F-Droid · Google Play
Bottom line: For minimalists and open-source purists.
7. AODNotify — Best notification-aware always-on
AODNotify wakes the always-on display when a notification arrives, showing an app icon and time without unlocking. The customizable clock face sits at the top of the AOD by default, and you can size, color, and font it separately from the notification row.
Where it falls short: Notification-driven wake means more battery draw than a static AOD. On phones with aggressive doze modes (Xiaomi, especially), the notification wake sometimes misses.
Pricing:
- Free: All features with ads
- Paid: $3.49 Pro removes ads and unlocks premium clock faces
Platforms: Android 8+
Download: AODNotify on Aptoide · Google Play
Bottom line: For people who miss the Nokia-era notification LED and want a modern software equivalent.

If your phone doesn’t have a native always-on display: Always On AMOLED fills the gap on OLED hardware.
If you have a Samsung Edge phone with a curved display: AlwaysOnEdge respects the edges the way OEMs never did.

FAQ
What is the best lock screen clock app for Android?
For most people, KLCK Kustom Lock Screen Maker gives the most customization for the lowest one-time price. If you’d rather not learn a template editor, Chronus is the fastest path to a nicer clock widget.
Can I change the clock font on the Android lock screen without an app?
On stock Android 14 and later, you can pick from a handful of preset faces. Font selection is limited to those presets. To use a custom font, you need a third-party app like KLCK or Chronus.
Do lock screen clock apps drain the battery?
Static clock widgets like DashClock and Chronus draw almost nothing. Full lock screen replacements and always-on display apps use more battery because they hold parts of the display active. Budget an extra 3 to 8 percent daily on a modern OLED.
Will these apps work on Samsung One UI and Xiaomi HyperOS?
Chronus, DashClock, and Fitness Watch Face work as widgets on both. Full replacements like KLCK and Always On AMOLED require granting accessibility permissions and may fight the OEM’s battery optimization. Test on your specific device.
Is Always On AMOLED safe to use?
The app is safe. It does request accessibility permissions, which sound alarming but are needed to keep parts of the display awake. Grant the permission only after confirming the source is the official app on Google Play or Aptoide.
Do any of these work on Android 17?
Every app in this list runs on the Android 17 canary as of testing. Google’s own lock screen customization improvements haven’t shipped as a final release, so these third-party apps still offer more control.
