We need to create a notification application that could be run on iOS and Android platform and have the ability to receive notifications (whatsapp kind of notification).
1. iOS and Android users to download the app from App Store
2. For the first time use, users to authenticate themself with a userid and password (assume a seperate webservice not in the current scope of work available for this authentication)
3. If authenticated, users phone will be registered along with their user id in the backend (assume a sepeate web service is available for this).
4. Finally when a backend systems wants to send out a notification, it will call a web service with the message and device id and it should be shown on the respective phone
1. It should be possible to create messages on different subjects
2. Messages will be shown to the user based on different subjects
3. Users can subscribe/un-subscribe messages froma specific subject
If there some 3rd party notification service that needs to be purchased for this application, please let us know.
