Bouncie helps you monitor both your fuel levels and your fuel economy for most vehicles. Sometimes, this information is not reported to the OBD port, so Bouncie cannot read the levels.
To see your fuel level, pull down the blue header in the app. If fuel level is being reported, it will be shown alongside your battery level.
If fuel economy is being reported, you can view the information within the details of each trip. Tap on a trip in your history to view the details. You will see details for the trip including how much fuel you used on the trip and your fuel economy in a MPG format.
