I have to admit I use the app all the time but I'm lowering my review to three stars until they fix the Apple Watch issue. The watch basically requires that the app be open on the phone to use which is pointless. I just want to tap on my watch and use the app with my phone in my pocket. This isn't a huge issue but if it worked flawlessly like the phone app does then this would be very nice. So the Tesla app has two big drawbacks. There is no option to use your fingerprint. The other is that the app takes too long to log into the car before you can actually use it. I tried the Model S app and it worked for a while but of late it just flat out stopped working. The other negative of this app is that it really tries to do and show too much on on one screen. This app does exactly what I need. It opens and locks the doors and it starts the car with my fingerprint. It also shows and does more (sunroof, set environment controls, opens the charge port, shows the car in a map, etc) but the things u really need are right there in an uncluttered view and the display is user modifiable. So, if the three apps I've tried, this one is head and shoulders above the others. For a suggestion of improvement, the designers should consider showing a percentage open on the sunroof tool. As it is right now, you really can't tell if the sunroof is open by looking at the depiction. Great app.
