Drain battery!

Watch out it drain battery!!!! It has a function to turn off checking at night and so doing night time battery drain is ok, 3.8 mile for 15 hour, but doing day time is almost 1 mil per hour!

Great product for the Tesla driver

I've been using TezLab since getting my Tesla and have really enjoy it. The information helps me figure out how best to drive my car. I enjoy using the in car dash as well, it's a great addition. All of the supercharging and home charging information is super helpful. If you own a Tesla, Tezlab is really the best companion.

Have to restart every time I open. Opens to blank screen. Have to quit and restart. Entering password is a nightmare. App deleted.

Good but

Great app but wish it would tell you top speed on each trip. I only see average speed data and that’s not good enough - Would like to monitor my sons speed - To the developers - Please add more speed detail on trips - otherwise very good app

Can’t get past login screen

Tried twice, using Tesla credentials, then says Tesla Verification Successful, then nothing. What am I doing wrong?

Great app but ..

Everything about the app is really cool and gives tons of info and even gives you PDF exports on driving/charging history! That’s awesome. My main thing is that I wish there was a way to change your personal name on there. I put my full name without knowing you can add friends and others on there. If you could add a feature that enables users to change their names, it’ll easily be a 5/5 app

Nice app, but overpriced

$30 annually is a bit overpriced considering what the app offers.

Can’t go pro with performance issues on app

I’ve been using TezLab since 2018. Now performance on the app was always an issue. But with all the pro features offered, I was up and joy for it. But you can’t expect people to stick around with these same performance issue you had for two years. Address your app issue or I’m fine using Teslafi and others resources.
