IPV4 Text Chat can be used to send text messages to someone who also has IPv4
Text Chat installed on their device. It uses IP addresses instead of
phone numbers to exchange messages. This app is experimental and may
have a lot of bugs. It was developed with Pythons Kivy Module and uses
sockets to communicate via the IPV4 Protocol. A has to listen for
connection while B tries to establish a connection. After a connection
has been established text messages can be exchanged freely between both
entities. This app works on your local network, but can be used on an
external network if you forward a port to your device. For more
