Description

Been using Watt Key — Watch App for Tesla for a couple months now. It’s basically an app that lets you control your Tesla from your Wear OS watch. Pretty solid if you’re into that kinda thing.

Here’s what you can do: You can automatically unlock and lock your Tesla as you walk towards and away from it. There’s also a feature that’ll unlatch the driver’s door when you approach. And you can open the frunk, trunk, and charge port with just a tap. It’s got a handy little tile on your watch face for quick access to all the commands.

Look, if you’re a Tesla owner, you’ll probably like this app. It’s not perfect – the setup can be a bit tricky at first – but overall it does the job. Worth checking out if you want to control your car from your wrist.

Editor Opinion

So here's my honest take on Watt Key — Watch App for Tesla. I've tested a bunch of Tesla companion apps and this one's pretty solid. The automatic unlock/lock and door unlatching features work great and save you a lot of time. The watch controls are really convenient too. But the setup process can be a pain, especially if you have multiple Teslas. And it's not the most polished app out there - some of the UI feels a bit clunky. Overall though, if you want a simple way to control your Tesla from your watch, Watt Key is worth a shot.

Support over email has dried up sadly but until then a really good app. Would like to be able to customise what is on the tile but I can't seem...

Don't work with my Watch 5 Pro. After installation, it works and a few hours later the watch does not find my car and do not connect anymore.

Awesome app! Very useful for those random times when I go out to my car and I leave my phone in the house. I might even use it as the...
