Raspberry SSH Lite is an app that allows you to control your Raspberry Pi, Router, PC and other devices via SSH. You can use it with your mobile device or PC. The app is completely free, and you can download it from Google Play. It offers a trial version that allows you to use the app with two buttons. It is limited to these two buttons for now, but you can buy a full version for a small fee if you find it useful.

The app has been designed to be easy to use, so if you don't know how to set up an SSH server or how to connect to your device, you can just download the app and follow the instructions. It is designed to be compatible with all devices that use the standard SSHD protocol.
