Siri Shortcuts have been added to the app, so at long last it's possible to control Nest using Siri without weird workarounds, and also get a nice feedback to see and hear what happened after your command. Note that once the shortcuts are created, you can use Siri on your Watch and even on your HomePod to control the Nest. Watch can be alone on LTE, and it will still work. Support is also added for new Series 4 watches, and watch face complications.

I have confirmed that the latest 5.6 version of the app works - flawlessly - on the Series 3 Watch LTE connection. In fact, it works even faster than when the watch is connected to the phone's BT connection. This is another thing that Nest's own watch app, at least at the time of writing this, cannot do. Similarly, my other Nest app, Watch Cam, also works great over the Watch LTE.

Version 5.0 is now out, and it now also features Apple TV app (on top of the Watch app and a Notification Center Widget). One purchase unlocks the download for both the iOS and Apple TV.
Thermo Watch - App Store Link
Considering that Nest has released their own watch app, I feel it would be a good idea to post some advantages Thermo Watch has over their app:
• Watch app works over the LTE connection on the Series 3 Watch. No phone needed.
• Apple TV app
• Notification Center Widget
• Quickest adjustment possible - you don't have to wait for an initial sync to complete before you can start adjusting the temperature.
• Complications on the Watch app. Complications show the set temperature, ambient temperature, humidity, HVAC mode and status.
• Audible and tactile feedback (on both the watch app and the widget) to confirm that the change you made has actually been applied on your thermostat.
• Full screen swipe/up down on the watch app to increase/decrease the temperature.
• Faster Watch app - both in terms of of how quickly the thermostat can be adjusted, and how responsive the app is.
• Voice control through the watch app. The app can be set to require just one tap on the complication to launch into the voice input mode, making it very close to native Siri control experience.
• Settings that, for example, make the digital crown sensitivity, tactile feedback on crown spinning, and a few other things adjustable.
As always, I'll keep updating it with anything useful I can think of, and I'll be listening to any feedback, so tell me what you think.

After many weeks of perfecting something that has started as a personal project born out of my frustration with the lack of the official Nest app for the Apple Watch - and the lack of quality in the available 3rd party apps, today I've released Thermo Watch. It's the app that lets you control your Nest Thermostat using your watch.
- The app lets you adjust the temperature in the simplest and quickest way I could think of - right after you launch it (from the watch face, tapping on the complication) you spin the crown to adjust the temperature.
- In the heat/cool mode, you first tap the dial you wish to adjust, then spin the crown. The scaling of the dials is smoothly animated - I tried to add as many of these little unobtrusive polishing touches as I could.
- Force touch lets you access additional features, such as the hvac mode change, setting/ending the away state, fan on/off, and a novel feature where you can speak the temperature into your watch, and it will be set.
- I really wanted to make something that won't just be useful, but feel truly native, responsive, and stable - and hopefully nearly indistinguishable in terms of quality in look, feel, and operation from Apple's own apps bundled with the watch.
- The app has been reviewed and approved by Nest's QA department (who seemed quite impressed by it btw) and is featured on their website in the partnership program "Works With Nest":
https://workswith.nest.com/company/marconelly/thermo-watch
- There is a glance and a full set of complications available. One of the complications for the modular watch face is designed as a ring, so it looks like a mini thermostat dial, with the temperature number in the middle. This ring also changes color to show if the system is heating or cooling, and also shows the Away state.
- The app can handle multiple thermostats in multiple homes - just swipe left and right to access them.
- If you wish to feel extra geeky with the voice feature, you can even speak whole sentences. As long as there's a number somewhere in the sentence, that will work too. For setting the temperature in the heat/cool mode, you should say something like "75 dash 82", and it will set both the heat and cool dials.
I've been using the app for several weeks now - it's been very reliable, and I find it's really the quickest way to adjust the temperature - you can start adjusting literally the moment the app opens, even before it finishes the state syncing. People at Nest have also been testing it for all kinds of unlikely edge cases, and it all worked fine.
The app is $2.99. I figured this is something for a niche audience, and people who need it, would hopefully be willing to pay a few dollars for it. Early on I've been tempted to give it away for free, but I've spent such obscene amounts of time perfecting it, that I won't lie I wouldn't like to see some reward for it.
