Wasn’t able to make one anyway because my usual and only email is “invalid” by this app’s standards ### 5/5 — Danny *2026-03-24, version 1.15* The app was easy to install and using my iPad pairing was straight forward I did full diagnostic on my car and fully satisfied with the results. Highly recommended. ### 1/5 — Does not connect *2025-10-18, version 1.12* Rubbish.. This does not connect to my 2020 fiat 500 Abarth 595 so therefore cannot reset the maintenance light..??? ### 1/5 — Waste of money *2025-09-20, version 1.12* Can only be used on 1 car or phone changer either and the device stops working saying already registered to another vehicle ### 2/5 — Doesn't really have info *2025-07-15, version 1.11* This gets the basic codes and some extra codes that I think are Toyota codes. But not codes i can change like turning off the seat belt alarm. Also doesn't turn off the maintenance light but did automate filling in the search field on Google so i could research how to. I'm familiar with doing that because it displays detailed information about every trouble code the same way. I've been asleep it seems witb uses of LLM Ai like ChataGpt or even their country's Deepseek. I use those to summarize my Internet content searches now to save lots of time. But to say I've been asleep, then they are Rip Van Winkle. I can imagine them now saying what is this Rip van and what is Ai? Be ready to do your own research on the codes because this app doesnt have it. It actually doesnt have info on my 2015 Toyota Camry which is a common car in the USA. Maybe they only have info in Chinese made cars like Ford and GM. Feeling a bit bamboozled about the lack of info. That would drop it to a generous 3 star. But after an update that I had to do and want to because it might actually have the info it lacks but it never does. Two of the bonus features that they generously give is having to log in with a user name and password every time i use the program. I dont know why it need that. I guess if im borrowing someine elses phone and happen to be in tbeir car and I'm showing off my Advancer. AD20 and they don't have the app then i can install it and get my car info. ### 1/5 — can’t do anything *2025-06-30, version 1.9* Hopeless device, can’t register, can’t login, can’t contact support, in fact can’t do anything, the dongle was a total waste of money. I would not recommend. ### 1/5 — Sad support *2025-05-14, version 1.9* God forbid you need support at 11AM on a Wednesday. That's not "standard business hours" account recovery is non existent, and if you create another one you can't use your device. If you lose your log in, you've thrown your money away. Do not purchase unless you prefer to piss money away. ### 1/5 — Doesn’t work *2025-04-17, version 1.9* This app worked for a while but now it won’t let me log in or connect my device. Every time it loads the request times out. ### 1/5 — No working *2025-03-23, version 1.8* I have changed the phone now the app doesn’t logins ## Frequently asked questions about Advancer AD20 ### What does the Advancer AD20 app do?
