You are curious what new features the new WhatsApp update will bring? New Emoticons? New functionality? New layout?
Why waiting so long untill there's a new version in the Play Store?
This app is looking for official pre-releases, that are released before a new WhatsApp release hits the Play Store.
If you want this app checks periodic if there's a new pre-release and notifies you. If you want it can install the new release. Yes the PlayStore-Version can become higher than the Server-Version. In this case this app notifies you that there is a new version and the download-button leads to the official PlayStore-entry of WhatsApp, so you can update as usual. Now there's a setting for tablet user to prefer server-versions only and disable notification on new PlayStore-Versions.
Stay bleeding edge and up2date :-).
To be able to install the prereleases you have to activate Allow app installs from 'unknown sources' option.
The new WhatsApp-Version is temp. stored in the default download-directory
