No complaints. Cant be much easier to use. Even a child could use the app. No issues connecting BE (note: tester needs to be connected to battery BEFORE trying to connect phone. The tester obviously needs power, hence why it must be connected to battery before opening the app)

Useful set of tests from app. I had a problem with my original BT20 which was swiftly resolved by Topdon - very impressed with the service. 1 star deducted from review because the app reports an error when I try to check for a firmware update. 5 stars if this is resolved.

SOC & SOH were added to the app. Please add the measured CCA, so I can compare it to the rated CCA. Lots of cheap battery testers show the measured CCA, so it's strange that this doesn't. This app wants questionable permissions, including: my contacts, my precise location, access to the camera, photos, videos, & storage. The app also requires you to create an account just to see the device's current firmware version and to install firmware updates (none yet, but it gives a null error pop up).
