User Reviews

ThinkDiag+ is a capable, affordable diagnostic tool with a broad feature set and solid support, highly valued by DIY users for value and usability. However, recurring subscription costs, mixed UX, coverage gaps for certain vehicles, and iOS/app stability concerns are recurring drawbacks to weigh against the benefits.

Strong value for money; affordable bidirectional scanner compared to expensive alternatives.
Easy to use and helpful for preliminary diagnostics.
Good app-to-hardware integration, appealing to DIY users.
Reliable customer service and support.

Cons

Ongoing subscription costs after initial period; perceived as expensive.
UX/UI can be obtuse and not always intuitive; needs improvements.
Gaps in vehicle/brand coverage and some models lack certain diagnostics; some firmware/update issues.
iOS app reliability and cross-platform compatibility issues; some functions/workflows don’t work as expected on iOS.
Reports of accounts or activation issues and concerns about devices being dependent on subscriptions.

I’ve been using ThinkDiag for vehicle diagnostics and have been impressed with its features and ease of use. The app connects quickly, provides clear fault-code information, and offers useful live data that helps with troubleshooting. The interface is user-friendly, even for someone who isn’t a professional mechanic. It’s a convenient and cost-effective tool for monitoring vehicle health and diagnosing issues before they become major problems. Overall, it’s been a valuable addition to my automotive toolkit.
