LANPUSH

LANPUSH is a utility to exchange text messages between devices in the same local network.
No internet required! No login! Just send a message and all configured devices in the same LAN will be notified with it.

LANPUSH is available for PCs with Java (Windows/Linux/Mac) and phones with Android.
For the PC client, check the project on https://github.com/leandrocm86/lanpush

Important notes:
- Although the app consumes little power, Android often tries to kill it on the background. Because of this, the app has defense mecanisms to wake up on its own and might never stop unless you exit it properly. If you want it to stop, click the menu option Disconnect and close.
- To prevent missing messages due to Android killing the app too frequently, it's advisable to add LANPUSH to your device's optimization whitelist.
- Android devices might not receive messages coming from broadcasts. When that's the case, you may have to add each Android device IP on the IP settings from the sender devices.
