My name is Marc Pujol and I have developed Teslastics (https://teslastics.com), a platform to monitorize and analyze your Tesla.
Once you create an account and link your car, it will capture every single drive and charge.
You will be able to access them and see their details in charts, images and more...
It tracks your battery capacity and warns you if it decreases. You can view your battery degradation.
It tells your driving and charging efficiency at each location.
You can tag locations and set a price per kWh. Then it will calculate all your charging costs.
It doesn't prevent the car from sleeping to minimize the vampire drain.
It also has a calendar view, map view, email notifications, and much more features...
Accessible through computer, mobile, tablet or even the Tesla browser.
Available in English and Spanish. Working on more translations.
More details are available at its webpage.
I would love to receive feedback from users and new ideas.
