Karai by DriveKey

I’m an environmental science teacher, and I’d previously used OffCents for years to track my own carbon emissions, and as part of our climate change unit with my students. That app stopped working last year, and I’ve spent some time looking for new alternatives. Karai seemed to be the answer, even though I dislike that it requests your license plate number rather than your model of car. We’ll, it’s working fine for me personally, but I have a large number of students whose plate number can’t be found, and they’re unable to enter in information manually. Moreover, a sizable portion of those who do have their car in the app—and location tracking allowed—show no activity in spite of frequent driving. I’ve been unable to find tutorials, blogs, or any other support material to be able to figure out what’s going on. It’s embarrassing to have suggested this as a teaching tool and to get such inconsistent results.
