The Android lock screen has evolved many times over the years. There have been various slide-to-unlock methods and OEMs have always put their own spin on things. As it turns out, there are also a lot of lock screen apps in the Play Store that can do even more. They’re not as popular as they used to be. However, many people still enjoy the allure of a new lock screen. These days, we usually recommend people just use a finger print scanner to bypass the lock screen altogether. It’s okay if you don’t want to do that, though. Here are the best lock screen apps for Android! In 2018, we lowered the number of apps on this list from 15 to 10. Lock screen replacement isn’t quite the bustling and energetic market that it used to be and we didn’t want to stretch the list for the sake of numbers because we were starting to recommend old, discontinued, non-functioning apps. There are still some good stuff here, though!


AcDisplay

Price: Free / $1-$80
DOWNLOAD ON GOOGLE PLAY
AcDisplay is one of the most popular lock screen apps. It emulates the always-on lock screens of devices like the Moto X, Galaxy S8, and others. Users can play with notifications without unlocking their display. It also features some customizations. For instance, you can set it to work only during certain hours to save battery life. More and more devices are coming stock with something similar. Thus, we'd only recommend AcDisplay to those with older devices that don't already have this feature. Its last update was in 2015. We're not sure if the developer is doing much with it anymore. At the very least, it's free to download and play with.

CM Locker

Price: Free
DOWNLOAD ON GOOGLE PLAY
Most of Cheetah Mobile's apps are trash. This one isn't so bad. It's a lock screen app and applock hybrid. It features the usual array of security precautions along with the ability to lock apps as needed. That way even if hackers get through the lock screen, they still can't easily get into your apps. The app also features HD wallpapers, notification support, a news feed, and intruder selfies. There are some advertisements. They may or may not bother you depending on your tolerance for such things. It is otherwise free with no in-app purchases.

DashClock Widget

Price: Free

DashClock Widget isn't technically a lock screen app. It's actually a lock screen widget. However, it still works for a list like this. It delivers the basic stats like time, weather, and some notifications. There are extensions available that increase the number of things you can do. It's actually more effective than most lock screen apps. However, it's only available on devices running Android 4.2-4.4. The number of people with devices running that gets smaller every year. It's still perfectly usable as a home screen widget, though!

Hi Locker

Price: Free / $1.99
DOWNLOAD ON GOOGLE PLAY
Hi Locker is a fairly typical lock screen replacement app. It'll show you the basics such as weather, notifications, calendar events, etc. You can also have it greet you with funny quips and greetings. It even has fingerprint support on devices with fingerprint readers. You can also have it auto-set wallpapers from Flickr. There are some customization options as well. For instance, you can have it hide notifications from certain apps so people can't see it. It's not even close to the most complicated lock screen apps, but it's a great replacement for those who don't need a ton of features.

LokLok

Price: Free with in-app purchases
DOWNLOAD ON GOOGLE PLAY
LokLok is different from most lock screen apps. It's almost kind of a mash-up of a lock screen and Snapchat. Turning on the device will open your camera. You can take a picture, draw on that picture, and then send it to your friends or loved ones. They'll see the image when they unlock their phone next and can respond accordingly. It's not great for sending risque pictures, but it's excellent for reminding someone to grab milk on their way home from work. The app is free to use. There are in-app purchases for things like sticker packs.

Screen Lock Guardian focuses more on security than most lock screen apps. It works with you setting a code. Those that break the code will have their picture taken.

The app also shows you the weather, has a quick launch bar with up to five apps, and more. It isn't the most customizable lock screen. It will definitely show you who's been trying to peep at your info.
