THINKDIAG is an automobile diagnostic tool with professional-grade functions. In the past, mechanics and car tuners have to use bulky diagnostic tools with large screens and connector cables, or laptops plugging into the OBD II port. 

THINKDIAG changes that. Plug the THINKDIAG dongle into your car, connect it to your smartphone via Bluetooth, and your smartphone becomes a professional diagnostic tool.

Manufacturer software

Each THINKDIAG you purchase comes with one free 1-year manufacturer software subscriptions. Each manufacturer's software has a retail price of $39.95 per year.

Each manufacturer software subscription gives you access to ALL diagnostic functions, including read/clear codes, live data streaming, actuation tests, and ALL maintenance functions of the manufacturer you picked. 

You'll have access to the car models from the same manufacturer! For example, if you purchase the Lexus software, you will be able to use it for Lexus AND Toyota since they are both under the same manufacturer!

Why did we choose to offer subscriptions?

This decision is made after careful thought and review of user feedback. Instead of charging you high one-time fees, we give you the flexibility and choice of renewing your subscription after one year. Users who change cars after one or one years can choose to switch to a subscription to another car manufacturer.

After activating the device, depending on your pledge, you may select any one or more manufacturer software at your choice in ThinkStore.

Each manufacturer software subscription comes with all 16 maintenance functions for car models from the manufacturer.

For example, a repair shop needs to use the ABS bleeding function on all car manufacturers since their customers will have all sorts of car brands. Maintenance function software has a retail price of  $49.95 per year.
