  • able to activate full brands with service functions unlocked (check: How to activate thinkdiag full brands?)
  • able to see data that other cheaper scanner couldn’t do
  • Downloading the app and setup was very easy.


  • You do have to pay an annual software update/license fee for the enhanced/bidirectional software. (Basic OBDII always works.)
  • The locked bootloader can only work on thinkdiag server. After the subscription expires it turns to a normal usb dongle and they want $40 dollars per make.

  • Various advanced service functions.
  • Picks up car information automatically (Auto-VIN).

  • Costly if you want to use on a second vehicle.

  • Good tech support.


  • Inconsistent;
  • not support ABS and transmission for all cars.
  • no other special functions

In sum:

Thinkdiag and Ap200 are subscription per make. Both come with 1 year free subscription for 1 make.

thinkdiag is bidirectional code scanner and can do actuation test and special functions.  Similar to thinkplus or X431 pro scanner.

AP200 only read, clear codes, live data, and some resets. More similar to an MK808.

Bluedriver is a simple obd2 code reader, only read, clear codes, live data. Similar to ELM327 and its app.

If you are a DIYer, we would recommend Bluedriver over ap200 in terms of per make subscription and update cost.

If you are a professional user, we would recommend Thinkdiag over Autel ap200.
