iGaugeBLE

iGaugeBLE is a free app that is part of an accurate fuel level reporting solution for vintage Volkswagens. The iGaugeBLE app is a Bluetooth LE fuel gauge that works together with a custom designed fuel sensor and a microprocessor. The sensor's readings are transmitted to the app via Bluetooth LE then displayed as a gauge graphic displaying the tanks current level from empty to full and updates in real time. There are currently four different gauge styles to choose from and are easily selected by just swiping left or right on the gauge face. Also included in the app is a speedometer that can display either MPH or KPH and requires no additional hardware to use.

Verdict
The clearest difference is update cadence: Fuel at every 10 months against iGaugeBLE's every 25 months. Fuel also leads on iOS requirement (13.4 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
