Conversations in the InVision iOS app gives you easy access to notifications and @mentions for your prototypes and boards. Tap the conversation icon to launch your notifications in the InVision iOS app.  

The first time you access Conversations on your mobile device, you’ll need to tap Turn On Notifications, then select whether you’d like to allow the app to send you notifications.

In the Conversations feature, comments and conversations from all prototypes and boards display in chronological order, with the most recent comments first. To see comments from a specific prototype, tap on the prototype you'd like to view.
Once you select a prototype, you can tap on a comment to view, respond, add other comments or to resolve. Use @mentions to notify the screen owner, those who are collaborating on the prototype or participating in the conversation.
