TezLab

TezLab is a companion app for your EV. Track every trip you take in your car, compete against your friends on various metrics like distance traveled or efficiency. Control your car's climate, max charge level, and locks within the app.

It's the app your EV deserves.

A supported EV is required to use TezLab.

Note: Only Tesla vehicles are supported at this time. We've been unable to get the support of owners/other EV vendors for connectivity to other car types

Disclaimer: This software and documentation are not provided or endorsed by the EV makers. Use TezLab at your own risk. TezLab uses some of the same interfaces used by the official EV apps, however, those interfaces are undocumented and unsupported by the EV vendors and HappyFunCorp cannot guarantee proper operation of TezLab. You are responsible for any changes to your car by using TezLab (car controls) as TezLab can unlock the car, and perform other functions on the car. HappyFunCorp is not liable for any damages to you, your car or any other object in conjunction with the use of this app.
