Zen Launcher is an Android personalization app developed by ZMenGames. It aims to simplify the usage of phones and tablets by uniting daily actions through its search feature. With Zen Launcher, you no longer need to open different apps for contacts, settings, calling, messaging, alarm, calculator, and more.

Zen Launcher is based on an open-source project, and its code is available on GitHub. The app has recently added several features, including a QR and barcode reader, an alarm clock that allows you to set alarms by typing or speaking, a lock feature, notification bubble support, multiple widgets, and blue light filter. It also supports direct dial or message to contact with social media apps like Signal, WhatsApp, and Messenger.

Zen Launcher's badge support shows the number of unread messages from your favorite apps, and a button allows you to quickly see apps that have unread notifications. Additionally, the app has an improved calculator, contacts can be shown separately in their own list, apps can be shown in grid view, and gesture support is included. As a bonus, Zen Flashlight widget is also included in the app.

Overall, Zen Launcher is a great app for those who want to simplify their daily actions and keep their phone usage as Zen as possible.
