Over a year with TezLab.

This platform has been an incredible source of data for myself as Drive over 70,000 miles a year in my Tesla. I’ve been able to log my actual battery health and capacity over long time scales and extreme use cases. It’s awesome to garner reliable data around actual range, real world efficiency and even the INCREDIBLE ability to plant trees to actively combat carbon production from charging the vehicle. There’s just so much good information and a fun way to get achievements and “mayorship” of charging stations.

More than worth the price for the pro version and excited for future integration of different types of EVS like the Mach E and ID4. I really hope this happens.

Nice App and Great Cause (carbon neutrality)

Really like what this app is trying to do, but only gave it four stars because I think it can be made “great” by making a few tweaks. Specifically, on long road trips, I’m awarded bronze, silver and gold badges for driving efficiently, keeping a consistent speed or fastest time covering a certain number of miles. I’d like the app to feature a trophy case (visible only by the user) to contain these achievements. As it is now, they get tossed into the ocean of other members’ achievements and aren’t readily accessible. Also, I’ve paid nearly $200 to purchase actual trees that will be planted to offset my carbon generated by charging, but that investment isn’t really celebrated as well as I think it should be inside the app. There should be a more thoughtful, graphically rewarding page I can refer to within the app that shows the region(s) of the world in which my trees are located, and when they were added.

Developer Response ,

Thanks for the feedback! We are working on both of the things you mention above for the future :)

Overall great app

I’m a new Tesla owner and I love this app more than any other app available on the AppStore (yes, even over the paid ones). It makes it really easy to see your drive efficiency. Not only that you can switch between battery percentage and miles with just a tap. With the Tesla app you have to change it within the car which can be frustrating and sometimes you’re just not near your car. You can see stats for each drive and charge session which is great! Overall a great app and highly recommended for new Tesla drivers!
