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. 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!

It’s important to note that lock screen apps aren’t as popular as they once were. As a result, we generally recommend sticking to the regular lock screen or using your device’s always-on display (if available). In most cases, you’re hitting a fingerprint reader to bypass it entirely anyway. Plus, third party lock screen apps aren’t more secure than regular ones anyway.


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.

Always On AMOLED

Price: Free / $1.99 (other options)
DOWNLOAD ON GOOGLE PLAY
Always on AMOLED isn't a lock screen, but it does emulate one. It basically mimicks the Always On Display feature of many smartphones. The app shows things like the time, notifications, and other such things. It also includes features like clock movement to avoid burn in. The app can even initialize doze mode while running. We only recommend this on devices with OLED display, including Samsung's AMOLED. It loses a lot of its luster on LCD screens.

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.

Floatify

Price: Free
DOWNLOAD ON GOOGLE PLAY
Floatify is a popular, somewhat modern option for a lock screen replacement app. It actually looks like a stock lock screen. It's a simple background with the time on the front. You can add things like weather, notifications, and other data. You can also customize the shortcuts on the bottom of the lock screen. It also has other modern features like turning the display on when you pick up your phone, themes, and a chat heads feature similar to Facebook Messenger. It's actually surprisingly good for a lock screen replacement. It hasn't seen an update since late 2017, though, so we're not sure this one is in active development anymore.

Hi Locker

Price: Free / $1.99

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.

However, it's competently done for the most part. There are a few quirks here and there, but it otherwise works okay.
