I got my Model S a few weeks ago, and so far, I'm loving my Remote S app, especially for its Apple Watch compatibility. It's great to be able to go for a run without taking my keyfob.
One small suggestion: would it be possible to make the four buttons visibly "press" when touched, in the car control screen on Watch? I refer to the screen that comes up when you touch the car icon, giving four options (turn HVAC on, keyless start, unlock, and lock). The Watch screen is small, and sometimes I miss the button with my fat man fingers. Right now, I can't tell whether or not I successfully tapped a button until I wait 5-10 seconds and see that my car didn't respond. But if the icon for each function would change somehow when touched (such as dimming a little, sort of like the + and - buttons do on the Watch page where you adjust the charge limit), I could be more certain.
Thanks for a great app, Allen! I'm gonna go give it a 5 star review now.
