Excellent Company & App

Some of the best work being done to enable all cars being more safer. Appreciate the hard work and effort to have a reliable app to control the systems of your car. It’s a Great world we live in now for a company to take on the auto industry just using your phone and OBD2 port of car. Keep up the great work!

1080p 60fps? Clever app tho

Clever app though. Very very simple to use and it doesn’t even require to save videos to your phone. Also, any way you can have different camera setting in the app for those people who have the 12 MP camera to record at 1080p 60fps? Thanks.

Good app, needs bug fix

When I try to scroll through previous drives to find a specific time in the drive, the video doesn’t keep up with the scroll bar. I could watch the entire drive to get to the point I am searching for but that takes forever. Please fix and will rate 5 stars.
