Doesn’t work

Did not work with the OBD2 device I got. I could not find the device when clicking can when connected to nothing. I connected to the unit via WiFi and it never popped up as a selectable device under scan and the app froze.
If I am on my home WiFi I click scan and it picks up devices connected to my personal network. I don’t know if the TACKlife unit works with this app.

All the 5 star reviews are because it makes you give it a 5 star review before you can use the app. Then the app doesn’t work... so all these good reviews are from lazy people who didn’t go back in and update their review after it didn’t work. How do I get my money back for this garbage app? Seems like a scam to me.

Disappointed and hot

I agree with everyone who purchase this app. How in the world can I rate this product without trying it out. Totally unacceptable .
