Microsoft launched Microsoft Flow not too long ago in an effort to combat IFTTT and originally when the Flow service launched mobile devices like the iPhone were unsupported.
Flow supports Microsoft tools like Office 365, Dynamics CRM, PowerApps, and Yammer.
With Flow installed and configured users can do things like get a text message to your mobile device when your boss emails you or save results from a twitter search to an Excel file to share.
For users who handle lots of photos or other files, you can do things like copy photos from Instagram to Dropbox or copy other file types from OneDrive over to SharePoint.
The app also has an activity feed so users can keep an eye on recent Flow actions in one place.
Microsoft plans to expand the capability of the app over time including the addition of the ability to add flows from the mobile app.
