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

Developer Response ,

You can now change your name. Please go to settings. Please consider giving us a 5 star now.

Please improve the algorithm for battery capacity

I really enjoyed this app with just one improvement in mind. The current battery capacity calculation was launched with 90%ending charge and 25% incremental charges. A lot of the online advices suggest to charge my car daily to 80% for better battery lifespan. Is it possible you change the algorithm of battery capacity to be launched with 80% ending charge?

Developer Response ,

Thanks! The reason it's at 80% is because battery health should only be calculated once in a while as it's a long term trend thing. The extrapolation equation is more accurate at 90%+ and since 90% charging is only once in a while, it avoids charting day to day fluctuations and instead, produces a long term trend. Please reach out to support@tezlabapp.com if we can help further!

Great app must have

Just picked up the 2020 M3P Self driving and Just trust me if you don’t have this app get it now you won’t regret it. The social aspect is interesting as well. It allows you to see and compare your efficiency, distance, charging with others. So for me I wanted to make sure getting and average 60 % efficiency wasn’t only me and I was right. Lol. Your welcome.
