A useful app for a Tesla owner. Still slow at times, but improved. STILL no tracking of phantom drain. I've been a pro subscriber from the beginning, but the updated pro pricing is almost 3 times what I've been paying so I'm not renewing. I was not really getting enough from the app to justify the old price, but was paying to support an app I want to stay around. I've adjusted my rating based on poor value for the updated pro price, and no phantom drain tracking. Still, it is a useful app.

Hi Joseph - thanks for the updated review - please feel free to give a shout at support@tezlabapp.com and we can give some more insight / clarify your request, as we're not able to determine your account level, etc, from a review. (i.e. some of the Idle Range Use detail is a Pro feature due to the amount of data crunching required).

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!

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!

What’s new

We have updated the track tab filter UX to make it a bit easier for people to find the filter screen. From there you can drill down on specific types of charges, drives or just filter by date for all data.
