  • Great app

    By Nicholas Wallace
    It’s a great app to add things for Tesla users that the official Tesla app doesn’t have
  • Must have app for Tesla owners

    By Elderonj
    Great app that gives way more infos than the official Tesla app. The free version is good enough for me
  • Charge tracking is sweet.

    By willbarr0
    Being able to see a readout of each charge, allows me to reimburse anyone accurately after plugging in, and I dig that.
  • Love the estimates

    By Emanon256
    I love how it estimates my cost to charge and cost per trip! Also the efficiency numbers help me strive to drive more efficiently.
  • Closes windows remotely

    By susanmick108
    Just parked my car at a charging station and walked the three blocks to my work. Got a notification from my Tesla app that the rear window was open. Rats! Do I hobble back to my car with my painful foot or....see if my Tesla app will help me. Nope! Hmmmm, see if TezLab has the answer to my problem. It does! Window rolled up remotely. Problem solved! Thank you!
  • Great app, with the money if you want to geek out on your Tesla

    By Keggman12
    Works great on my 2021 model S. At developer, would like to be able to adjust carbon offset manually though. My house uses wind source power from the grid and has solar panels, would like to be edit the CO2 value for each charge to reflect
  • Above and beyond the Tesla app

    By Dan1OB
    If you’re a data nerd, you’ll love all the analytics that Tezlab provides.
  • The app would not run for days

    By Kaikaikaicn
    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

    By ppanzica
    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.
  • Creating account
