Review summary

Reviews are mixed: users praise Ediag for its ease of use and broad, capable feature set and good value for money. However, many report compatibility gaps with certain vehicles and older data, frequent app instability and connection problems, and weak onboarding and support. Overall, the app shows potential for many users but reliability and model coverage are recurring concerns.

Pros

Easy to use and intuitive, with a simpler setup for many vehicles.
Broad diagnostic capabilities with many functions and advanced options.
Good value for money, offering features comparable to pricier scan tools.
VIN memory helps remember vehicles after the initial setup for quicker scans.

Cons

Compatibility gaps and outdated data limit coverage for many models and newer cars.
App instability and crashes, especially after updates.
Frequent connection issues between phone and device.
Poor onboarding and documentation; unclear terminology and slow initial setup.
Limited or slow customer support and responsiveness to bugs.

2026-05-29	An*****	This app and dongle have an absolutely amazing number of functional tests, live data, and perameter resets and even adaptation resets that would rival the very best scanners available under 1,000$USD.

2026-02-26	Gr*****	Phone losing connection with device repeatedly and on two different GM vehicles, false codes for exterior lighting are being thrown. Same code l, two different vehicles. Highly unlikely that both have the same failure. Observation of those lights does not confirm problem.
