This is *not* a SSH client - you must install a client first (recommending Juice SSH, but we're not affiliated in any way). This application allows you to connect to clients of your hot-spot, without knowing their IP addresses.
Android hot-spots and USB sharing are a convenient way to connect to Raspberry Pi and other embedded devices - however, there is no good way to guess the IP address of the device afterwards.
SSH Back scans the hotspot network range, and launches the favorite SSH client.
This application was written to support my own use-case, but it's relatively common one, so I'm releasing it for others to use. If you like it - or want more features or flexibility - reach out, maybe there is a product in it.
