Microsoft announces Office Insider Fast for Android and iOS

Basically, the Office Insider program will receive a Fast level, which should provide users with even earlier builds of Office. According to Microsoft, this level of access is the same that its employees have for testing applications internally.
If you want to be among the first to get to test new Office pre-release builds, the Fast level is what you should go for since you'll be getting them at the same time as Microsoft employees.
The Redmond-based company does mention that Android and iOS will receive the Fast level “soon,” but an exact release date has yet to be announced.
If you haven't tried Office Insider until now, then you should know that this is aimed at users who want to try out the earliest preview builds to identify bugs and provide feedback to help Microsoft patch them out before releasing it for the public.
