These apps are being updated regularly, so support for the VIECAR 4.0 may be added in the future. If you want to check if an app that isn't on the list is compatible, the best way would be to check the adapter settings in the Apps you have to see if there is support for "VIECAR". If there is no "VIECAR" option, try connecting to Bluetooth LE or Bluetooth 4.0.
