# ntfy Android App # ntfy Android App
This is the Android app for [ntfy](https://github.com/binwiederhier/ntfy) ([ntfy.sh](https://ntfy.sh)). This is the Android app for [ntfy](https://github.com/binwiederhier/ntfy) ([ntfy.sh](https://ntfy.sh)). It is available
in the [Play Store](https://play.google.com/store/apps/details?id=io.heckel.ntfy).
## Current limitations
* The app on the Play store only works with ntfy.sh, not with other hosts, due to the fact that background services in
Android are pretty much impossible to implement.
