You are right - the gap between apps has closed significantly. I bought this early on. Still use it to schedule a sequence of events - finish charging to x% SOC by 08:00 AM only on Monday through Friday, wake vehicle, turn on heat, turn on steering wheel heat, unlock doors, honk horn (so I know it worked while I finish the morning paper).
I also use different profiles - I charge differently when I go to my son's house for example. Or I have an "all in" profile to charge to higher SOC when a trip is planned. Also use the "not plugged in" reminder or remote "start HVAC" with a button, like when I'm about to leave a store on a cold day. And I like the audio UI better than the Tesla app for back seat control. Plus it's aware if your car is sleeping asking if you want to wake it.
Some things like software updates are much better with the Tesla app.
But that's me. YMMV.
