Ratings and reviews

Even with my phone off, TezLab polls my vehicle about once a minute. It should only ping from my phone and only when I'm using the app. Other Tesla apps and online services don't ping every minute like this. What is TezLab looking for that no other service is? Questionable security issues and draining my car's battery unnecessarily. Reply to TesLab: I constantly see only TezLab accessing my car while driving every minute. While I also have 3 other services I'm trying. Something is overzealous.

Very useful app for a Tesla owner. A few rough edges, occasional very slow. My main complaint is that the app doesn't make easy to track phantom drain. This is my single most desired feature. "Idle range use" is a start, but needs more detail and easier access. I really want to be able to track mileage from a full energy cycle point of view including when parked, as I would for a gasoline car. Tesla clearly doesn't want owners to track that. Tezlab "real world range" is good for this.

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!
