You can connect the fully configurable acoustic vario Blues via Bluetooth as an external sensor to a mobile phone, and you can use a cheap mobile phone without a barosensor as a full-fledged flight computer.

All vario parameters can be set from mobile via the new Blues vario application! You can find a detailed description of the application here.
