iOS 10.3 introduced new app review tools for developers in the form of the Reviews API. The goal is to allow developers to ask for feedback in a less intrusive way while also giving them the opportunity to respond publicly. The end result should be a win-win for developers and app users alike.
Pusher has released Beams, a push notifications API for mobile app developers. Pusher Beams allows developers to manage device tokens for iOS and Android apps. Developers can also use Beams to trigger notifications based on the in-app activity of users so that users remain engaged with their apps.
