I am a PHP developer and work with a small team of ~20 real estate agents. Lately there's a need for some server-to-person notifications (real time notifications, otherwise I could have used email for this).
There could be around 20-30 messages/day/person, mostly on iOS, but also a few androids.
So I've been looking at push notifications, which seem to do the trick, but all services I found (parse.com, for instance) seems to be for android developers (they need an app). I'm not an Android developer, and creating an app for this would probably take me too much time.
Does anyone have an idea on how to achieve this with a simple API?
I considered SMS at first (clickatell api), but the boss wants a free service (or a flat charge). Thank you for your advice!
[Update] - seems that I did not explain the situation correctly, I apologize for that I'm looking for a (maybe free) service that has it's own app in Google Play and Apple Appstore and will allow me, as a PHP programmer, to send push notifications in near realtime to any of the ~20 devices in my organization.
