It comes with a nice Android application available on the Play Store and F-Droid, that listens for events over a websocket.
I have been using it for about 10-12 days now, without noticeable impact on battery.
EDIT 03/2020: still using the Android app, and still no battery impact.
It is easy to send messages to Gotify:
$ curl -X POST "https://notifications.example.org/message?token=<apptoken>" -F "title=my title" -F "message=my message"
$ http -f POST "https://notifications.example.org/message?token=<apptoken>" title="my title" message="my message"
The token can be generated from the GUI or API.
When receiving a message, your Android will immediately notify you of any message.
The developers are very active, looks like a promising project!
Up until now, I was using Simplepush, which is basically the same concept but sends messages to Simplepush servers.
Also the Android app is not open source
Being not self-hosted you don’t control your data, and the developer can turn off the service overnight.
