In simple English
This app turns an old Android phone into a text message server. You plug a phone with a SIM card into power and connect it to your Wi-Fi. Your other programs can then send text messages through it using simple web requests. You can also receive text messages and send them to your own server using webhooks (a way for an app to send automated messages to another website). It saves you from paying expensive commercial text message services. The app is free to use on your own local network.
What it is
An open-source Android application that runs a local web server to handle text messages. It exposes an API (a set of rules that lets different software programs talk to each other) so you can send and receive texts from your own software.
