Above and beyond the Tesla app

If you’re a data nerd, you’ll love all the analytics that Tezlab provides.

The app would not run for days

Till I went to twitter. I am disappointed that the app charged us $2.99(now $5.99) and the developers would not let their users know that the app was having backend issues by sending an email

App does not work

Unfortunately my experience with this app is a bit to be desired. I can’t even get the app to create a login to Tezlabs. I can login to Tesla but the next step is to create a login for tezlabs. It FORCES YOU to upload an avatar and once you pick a picture to upload it just spins for EVER!!! So Frustrating to say the least.

Culprit of ghost battery drain and making a noise when your car is parked

This app is the culprit of a constant fan whirling or pump sound, when your Tesla is parked. And this app seems preventing your Tesla from sleeping, so it causes significant ghost battery drain. Please double check the battery with and without this app.

Too expensive

The annual fee is too high. But otherwise it does a good job at delivering what it is supposed to.

Best Tesla App!

I love this app as every Tesla owner needs this app to hear monitor everything in the car. Especially with the battery efficiency, charging and overall health of the car.

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!

I changed my Tesla account password and can’t login again

I cannot log in again after I changed my password. All the other Tesla app I use are okay. So I thought there might be a bug with this app.

Great app there is a bug where the screen turns white and you have to close it and open it. Really annoying
