Ratings and reviews

Please bring back landscape mode. Also, it asks for access to location, I thought it would have a speedometer next to the tach. That would be a huge plus.

App doesn't reconnect to the eflexfuel unit unless you power off your phone on a Samsung Galaxy S23 Ultra.

Otherwise 4 or 5 star app, depending how do you like the visual and UX design. BUT the Bluetooth connection is pretty dodgy. When it works though it's pretty great; clear and easy to use and does exactly what it promises.
