Always the last WhatsApp beta
If you don’t want to always keep an eye on the official website of WhatsApp or go to APK Mirror, you can use WhatsApp Beta Updater to get a notification when a new beta version is available. The application searches in the background for new updates (if the ‘Enable notifications is enabled), and can install it right away. This saves a few steps and ensures that you always have the latest version of WhatsApp.
Keep in mind that the beta version can have bugs. On the other hand, new opportunities, such as the call functionality of WhatsApp and backup via Google Drive were first available in the beta.
Download WhatsApp Beta Updater
WhatsApp Beta Updater was previously removed from Google Play because it would violate the terms of the app store. However, the app is now open source and available via Github and contains no ads anymore. There are several Material Design elements, making the app fits nicely into the design of the latest Android version.
