PushBots is a scalable, reliable push service for sending notifications out to application users, including those who use iOS or Android devices. It can be linked to an app's Twitter account to push Tweets as messages. Messages can be sent out to specific groups of users based on factors such as their location or their interests. The service also provides real-time analytics for tracking and evaluating messages and campaigns. PushBots' functions are made accessible for integration via REST API.
