If you know this, you distribute an app and develop iteratively. In the meantime, your testers report bugs that you have already fixed? This very often leads to tedious waste of time and a lot of overhead. We at Updraft know this only too well. Therefore we have developed a feature that should solve this problem: Autoupdate your app.
If the current app version of your beta tester is lower than actual uploaded version on Updraft, your beta testers will be informed with an in-app notification to install the new app.
To use the autoupdate feature, you have to implement the Open Source SDK available from us and enable the autoupdate functionality in the settings of the app within Updraft.
