Over a year with TezLab.

This platform has been an incredible source of data for myself as Drive over 70,000 miles a year in my Tesla. I’ve been able to log my actual battery health and capacity over long time scales and extreme use cases. It’s awesome to garner reliable data around actual range, real world efficiency and even the INCREDIBLE ability to plant trees to actively combat carbon production from charging the vehicle. There’s just so much good information and a fun way to get achievements and “mayorship” of charging stations. More than worth the price for the pro version and excited for future integration of different types of EVS like the Mach E and ID4. I really hope this happens.

Nice App and Great Cause (carbon neutrality)

Really like what this app is trying to do, but only gave it four stars because I think it can be made “great” by making a few tweaks. Specifically, on long road trips, I’m awarded bronze, silver and gold badges for driving efficiently, keeping a consistent speed or fastest time covering a certain number of miles. I’d like the app to feature a trophy case (visible only by the user) to contain these achievements. As it is now, they get tossed into the ocean of other members’ achievements and aren’t readily accessible. Also, I’ve paid nearly $200 to purchase actual trees that will be planted to offset my carbon generated by charging, but that investment isn’t really celebrated as well as I think it should be inside the app. There should be a more thoughtful, graphically rewarding page I can refer to within the app that shows the region(s) of the world in which my trees are located, and when they were added.

Thanks for the feedback! We are working on both of the things you mention above for the future :)

Good Info, But Lots of Notifications

I like the app in general, good info. But the main issue I have is the sheer deluge of notifications you get from this app. It’s far too many. I wouldn’t mind a couple, but I get about a dozen every time I get near my car. Way too many. And in the settings there isn’t a “disable all” option, so I had to go manually disable all 20 (yes, I counted them) notifications. But then, even after doing that, it did not seem to allow me to actually acknowledge the notifications in a way that removed the badge. This became such an issue that I simply disabled notifications for the app completely in iOS settings. It appears that’s the only way to completely remove the badge for some notifications. Like I said, good app, but too much annoyance for the small amount of good info that it provides.

Hi there! Thanks for your feedback.

If you have a badge on the app icon that isn’t clearing there’s likely an unread notification from some time ago. To clear, simply tap View All beside notifications on the main screen, then tap the three dot menu and tap mark all as read, that will clear the badge.

We don’t have a disable all option because the OS setting does that.
