It's a mobile app that polls an endpoint for json, after the user configures it (seemingly with a QR code), that's all. There's no middle-man server, and it's also not push.

Neat idea, low barrier to entry. Can't tell from docs how authz/authn are handled.

And who maintains the message queue until the client pools next(the service provided by these middle-man servers) ? And what about message by user identifier ?

And client app will eat my battery because one more service is constantly polling now ?

You can configure the refresh interval in the service response: https://refl.me/docs

Would be nice if you could override this client side as well.
