Comments on PROFLEX for Android

★★★★☆ Tim Springer · Sep 19, 2025

I bought my Proflex second hand. I saw the app ratings and my expectations were very low. However, the app does work, it shows the ethanol content, I had to reload the app initially to show the E85 content but the app does its job so far.

★★★★☆ Meric Kilic · Sep 11, 2022

Much better user interface than previous app, hope they add fuel temperature display as well, like the AFE kit does. Maybe even fine-tuning options of fueling too? App is crashing since new update.

App was Garbage Before, Update Works Great Now, The Re-Scan Feature Works

★☆☆☆☆ Breckon Carter · Jun 22, 2022

Opening the app is fine. Once turning the key on to see how much ethanol I have in my car pressed on the device after a little bit the app couldn't connect. Was so disappointed. I hope this is just a glitch.

Like others say hit or miss now it's a miss on connecting its getting annoying this needs a serious update other than that when it does work it's a straight forward app that will show u how my ethanol you are running witch is needed cuz alot of these stations are lower than others and a great way to know if I will return to that station or not
