It was only a few days ago that we saw the Terrain launcher debut on the Google Play Store, the home replacement app via Samsung Accelerator. Now Nokia is also getting into the game. Yesterday, Z Launcher was announced and released in pre beta form to Android users. The predictive launcher aims to bring relevant apps to the forefront before you have to search for them.
Z Launcher is different compared to many other Android home replacements, especially when it comes to accessing your apps. There is a small icon at the bottom of the main screen that shows all of your apps in a list, but a (somewhat) quicker way to get to the app is to draw a letter on the home screen to bring up apps and content beginning with that letter.
Given that it's in pre-beta status, it's not surprising that Z Launcher is severely lacking in features. It lacks the flexibility of even the most simple of home replacement applications, but it's novelty may be enough to at least give it a try. It's predictive nature is definitely interesting, as it will get better at guessing what app you want to use, based on time and location, over time.
According to the Z Launcher website, official support is limited to the Nexus 5, Samsung Galaxy S3, Galaxy S4, and Galaxy S5. I was also able to install it on the HTC One (M8) Google Play Edition and the LG G2. The G2 I installed the app on was rooted, which kept Z Launcher from opening.
Keep and eye out for Z Launcher, as Nokia will bring more device support and features in the future. Until then, it's a novel but severely lacking home replacement app that you'll probably get bored with quickly.
