I tried Unified Remote and obviously it is much better having been under developement for so much more time.

Unfortunately it keeps disconnecting from my phone, both WiFi and Bluetooth. The app is very bad at signaling if you're connected or not and at managing the connection parameters, and that doesn't help. They could copy JuiceSSH, which is not supereasy but better, or Syncthing.

Still, it doesn't work so I uninstalled it. Power-touch seems potentially better because it does so little that there is no danger of misconfigurations. It's much more hackable too.
