Ratings and reviews

I really like the pro version, it's nice to have the export ability. One thing I would really like to add is the ability to have set points when driving in cold weather. I live in MN and notice that I can lose up to 50% of my range in the coldest temps. If there was a way to have an app shut off the heat when it reaches, say, 70 F and then turn on again when it drops down to around 62 F that would be great! I find I'm doing this manually to get more range but it seems like something an app could do.

Nice app and good details. Wish it would let you also set the MPG of a vehicle alongside the cost per kWh and gas, which would allow a better savings estimate per circumstances. Looks like it figures 30mpg but I replaced a car that got around 45mpg, so their listed savings aren't actually accurate for me. Not a huge deal, the app is still worth it and great to use.

It caused a major phantom drain in my M3. Almost 6-7% every 24 hours. Workst part is they were collecting my data even after I uninstalled the app. I only got to know when I went to tesla service and they asked me to change my credentials which led to Tezlab not being able to authenticate to my car. That instantly fixed my battery drain issue. Really bad experience overall! You CANNOT keep collecting data after I uninstall the app!!!
