Was told it could be a bad ground. This is not the case. It all started, or stopped I should say, after the updates. Same issues with android as well, not just iOS. With no way to monitor, I pulled the system from the vehicle. Worked for about a year+. ### 3/5 — Update issue *2023-05-20, version 2.5.0* After update today. It connects after a while. Shows status of everything good. Then nothing. No percentage or even a button to push and see it. ### 3/5 — Cannot Connect *2023-04-25, version 2.3.7* After the update I can seem to connect to my module. Seems based on the past reviews this is a issue for more than me. ### 2/5 — Used to work *2023-04-22, version 2.3.6* For some reason it won’t connect through the blue tooth. It gives a weird message like it’s unsupported. ### 3/5 — Not connecting at all now *2023-04-20, version 2.3.5* After latest update, will not connect at all now ### 2/5 — Can’t connect to my Proflex module *2022-05-14, version 2.1.1* My app won’t connect to my Proflex fuel module! How do I know if it is still working? ### 4/5 — This app needs to be updated *2021-05-03, version 1.0.1* This app needs to be updated, doesn’t work with iOS 14.5 ## Most critical reviews (10 lowest-rated) ### 1/5 — This app it TRASH *2024-02-08, version 2.5.1* Garbage app never connects even though in blutooth settings will clearly show DUAL-SPP available to connect.....this app is GARBAGE 🚮 ### 1/5 — Can’t connect still after update *2023-04-27, version 2.4.0* Still won’t connect to the module. ### 1/5 — Won’t connect anymore *2023-04-26, version 2.3.7* My iphone no longe detects the device via Bluetooth. Used to work perfect but now just keeps searching and doesn’t find the device ### 1/5 — App not connecting to device *2023-04-26, version 2.3.7* After installing this today, the app is not connecting to the device. ### 1/5 — App is trash *2022-06-11, version 2.1.1* For the money I paid for the kit this is the only way to know if it’s working and it does not display anything but 0% on the live gauge and that’s if you can even get it to connect fix it or I’m returning it ### 1/5 — Gauge does not work.. reads 0 Ethanol *2022-05-23, version 2.1.1* Only reason I bought this kit was to use the Ethanol gauge to read the content but the app had not been updated in years apparently. Wish I would have known this before it would have saved me $499. USELESS!!! ### 1/5 — Broken *2022-03-05, version 2.1.0* After update I get no read outs, says it’s connected but no information ### 1/5 — App not supporting the latest IOS update *2021-05-05, version 1.0.1* Hope an update come soon ### 1/5 — Doesn’t work *2021-04-29, version 1.0.1* Just updated to IOS 14.5 and the app no longer works. App also hasn’t been updated for 3+ years. When will the app be updated? ### 1/5 — The App doesn't work, crashes when trying to connect. *2020-11-25, version 1.0.1* Like the title says. When I try to scan the pro-flex system. The app crashes. I have no idea how much ethanol I am running. For that mater how do I know the Advance Fuel Dynamics system even works? I click on app support and or goes to a dead page on the AFD website. ## Most praised reviews (10 highest-rated) ### 5/5 — Fix app for IOS!!! *2022-03-17, version 2.1.1* Cant read Ethanol % it takes a while to connect too. Sometimes it wont read at all. Plz fix this issue thx ### 5/5 — Help *2022-03-05, version 2.1.0* Needs fixing with the new updated app. Not able to read ethanol content now ### 5/5 — Flex fuel Installation *2020-04-29, version 1.0.1* This kit is so easy to install and use, anyone can make their vehicle flex fuel capable! Awesome product! ### 4/5 — Is that it? *2024-10-04, version 2.5.6* 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? ### 4/5 — Great sensor *2023-05-18, version 2.4.2* Had an issue with connecting at first but figured it out after I went in and enabled location in settings!! The app settings do not work so I had to manually do it ### 4/5 — Bluetooth *2023-04-23, version 2.3.6* After update can’t connect to the the device anymore to read the ethanol level anymore ### 4/5 — App connection *2023-04-21, version 2.3.5* Ever since update I haven’t been able to connect to the app via Bluetooth and can’t read mr ethanol levels. ### 4/5 — Need to fix *2022-06-13, version 2.1.1* App keep saying 0% ### 4/5 — Please fix *2022-03-05, version 2.1.0* Please fix app before update my real time ethanol value would read fine bow it just says Zero?? ### 4/5 — Update needed *2021-05-08, version 1.0.1* The developer needs to update this app because now I can’t access it with the new IOS ! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
