User Reviews

Users largely report PROFLEX Connect as unreliable. The main pro is that it can display ethanol content when the device is connected. However, the app suffers from persistent Bluetooth connection problems, missing or stale data readouts (0% or blank), and instability after updates. Compatibility with newer iOS versions is poor, with several reviews noting it hasn’t been updated for years. Some users also report crashes when scanning and the need to enable location services as a workaround. Overall, the app experience is repeatedly problematic.

Pros

The app can display ethanol content/level when connected.

Cons

Frequent Bluetooth connection failures and inability to reliably connect to the module
App often shows 0% or no data readouts instead of the ethanol level
App becomes unstable after updates and often stops working; poor iOS compatibility
App crashes during scanning or when attempting to read data
Requires enabling location services as a workaround; app settings are unreliable

Device itself great app 🚮

Absolutely love the product. The app on the other hand, is just bland. Seems like it was thrown together in about 20 minutes. I’d think for paying $1,000 USD they would at least put some effort into the app. The one and only thing is just seeing the ethanol content. Am I missing anything? Is there more?
