Total waste of money and it doesn’t tell you what’s supported until you buy a pack. ### 1/5 — App issue *2024-11-19* App issue can’t load the previous application ### 1/5 — Not working AP200 *2024-06-23* Since last update I can no longer activate my tpms relearn. Smh bug fix yeah right ### 1/5 — Für Ford Bezahlt und funktioniert nicht! *2022-06-18* Die App zeigt nix an und lässt keine Diagnose durchführen. Unverschämtheit ### 1/5 — They broke the app. *2022-03-16* “fix some bug” is what they said the update was. Yep, you fixed it alright. Locked my VCI box and made it a brick. No response from support at all. Shame on a company that randomly locks your device from being used for no reason at all. ### 1/5 — Doesn’t connect via Bluetooth *2022-03-08* The device does not connect via Bluetooth to the phone app. I want a refund. 😡 ### 1/5 — Not connecting , payed over $100 for additional features for nothing! *2022-02-14* Not connecting , payed over $100 for additional features for nothing! ### 1/5 — Won’t bind or connect *2021-09-04* Won’t bind or connect I had one a couple years back that was great and I lost it I recently had purchased one at the swap meet for 45.00 and it’s trash won’t do anything I know it’s not broke because the package was in open so I’m giving one stare for that reason I really really need it and it won’t work ### 1/5 — Keine Funktion seit Update *2021-06-21* Nach dem vergasenden Update lässt sich kein Ford mehr diagnostizieren. App ist leer, Verbindungen funktionieren nicht. Obd geht noch, immerhin. ### 1/5 — Doesn’t Show anything *2020-08-14* When I open this app the boxes that pop up don’t show what they r ## Most praised reviews (9 highest-rated) ### 5/5 — Jeep Wrangler JL update *2020-06-23* Please update Jeep Wrangler JL ### 5/5 — Check your junk email to register *2020-06-18* My registration email ended up in junk. Just mark it as not junk or add sender domain to safe list. Software works. Not sure if worth $60 and another $22 for additional car makes.. seems like the generic software works just fine. 👍 ### 5/5 — Locked VCI BOX **HELP** *2020-04-02* What do I do about this? Why is it happening? ### 5/5 — Works Perfect *2019-04-11* Read and followed the directions and it works perfect. ### 4/5 — Goes crazy *2022-01-22* Getting dtc’s is a bit tricky ### 4/5 — Works as advertised *2019-10-18* Honestly nothing impressive here. not that there should be, but I think it could use a redesign in my opinion. Also just so the developers are aware, the icon for the USA app has a silhouette of South America. I chuckled a while but honestly not a big deal. ### 3/5 — Bluetooth function is garbage *2021-06-27* I have to fight this stupid app to get to acknowledge the device. It says connect to Bluetooth yet Bluetooth says it’s connected device light goes from green to blue. Still the app says it connect to Bluetooth. ### 2/5 — Не особо *2021-02-23* Мало функциональный. Под одно авто, остальные платные. Бывает зависает. ### 2/5 — Nice when it worked *2020-07-16* It use to work great but after not using it for a while then needing it it no longer works I did the updates and still won’t work right. And it keeps having me download other apps. For how much it all cost this is stupid I had to go out and it and normal reader bc I couldn’t get this one to work --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
