Love this App. I've been using it since February 2020 and it can provide great statistics. The team has consistently added more features and are very responsive. The TesLab Dash, made to be used in Tesla's screen browser is amazing. Its estimated real range is super useful. If you want to record your drives to and from clients, it gives you the option to record and lately, to add notes. Than you TezLab Team!

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.

Great App. I was getting excessive phantom drain in my model S. Now I'm able to put it to sleep whenever I get home or work to make sure I retain as much battery charge as possible. Every once in a while it wakes up, but I've still decreased my phantom drain by a lot. It's also nice to see the efficiency of charging your car and power used from point A to point B. Recommended!
