I’ve just released version 1.0.0 of the Push gem. Which allows you to send push notifications to iOS (APNS) and Android (GCM/C2DM) devices from a Rails application. Right now it’s used in a production environment and I’m sending 500K push notifications a day. This gem uses the Rails database to store your messages so no additional dependencies are required. The daemon includes a customisable feedback service to integrate the feedback in your own environment (for example the removal of device tokens).
