* On May 16, Google / Nest have announced that while the "Works With Nest" program will end on August 31, 2019, this app will continue working indefinitely, as long as you do not migrate your Nest account onto a Google account.

* This app has been reviewed, and approved by the Nest QA department.

The app has Siri Voice shortcuts for seamless Siri control of your Nest, from the iPhone, Watch and HomePod. It fully supports Apple Watch LTE, and can work when the iPhone is not around - as long as the watch itself has internet access (either LTE or WiFi).

Thermo Watch offers the quickest, most intuitive way of controlling your Nest Thermostat:
• Using Siri voice shortcuts you can control many aspects of your Nest, such as instant activation of heating or cooling, direct setting of your favorite temperatures, increasing/decreasing the temperature, and setting the Home/Away state. Thanks to Thermo Watch, It's all finally just one casual "Hey Siri" away, all with informative visual and verbal feedback.
• From the watch face, tap on the Thermo Watch complication to open the app. Spin the Digital Crown, or Swipe up/down to adjust the temperature. You can start adjusting the moment the app opens.
• On your iOS device you can press firmly onto the app icon to open a quick popout menu, you can swipe to the notification center to adjust the temperature on the Widget, or you can just open the app. Again, you can start adjusting the moment the controls appear.
• From your Apple TV, open the app, and swipe up/down on the remote to change the temperate.

In the watch app, the Digital Crown behavior is carefully tuned for this purpose, so you won't be overshooting the desired temperature. The watch will let you know with a chime and a tap, that the thermostat has received and applied your command.

Monitor your Thermostats and Home/Away status right from the watch face, using complications that update in the background, without having to launch the app.

You can use Siri on your iPhone, Watch, iPad, or HomePod to control any of your thermostats. Record phrases that make most sense to you, such as "Start Heating" or "Make it Cooler". If you have multiple thermostats you can control them individually, by saying for example "Start Heating Upstairs" or "Start Cooling the Living Room".

Visit website for the detailed instructions of Siri operation.

The app supports multiple thermostats in multiple homes - just swipe left and right on your Watch screen to access them, or see them all at the same time in the iOS Widget and the app. Fahrenheit and Celsius are both supported.

Beyond that, you can press the Watch screen firmly for additional functions, like switching to a heating or cooling mode, setting the away status, or turning the fan on and off.

While the app's minimalist looks betray the simplicity of its operation, what they don't show is the amount of planning, design, development and refinement that went into it, ensuring it becomes something that is enjoyable to use and experience.

The goal was to make a product that would feel like it truly belongs to the Nest ecosystem, and that would not look out of place next to one of the apps bundled with the Apple Watch.

Please make sure to sign in with your main Nest account. Nest doesn't support Family accounts in 3rd party apps.

Please note also that this app can't work with Thermostat E with Heatlink, sold in Europe.

Thermo Watch does not collect any of your data. Your login information, thermostat settings, and any activity - all of it flows exclusively between your watch, your thermostat, and Nest Labs. Author of Thermo Watch does not receive any of it, at any point.

What’s New

Version 11.4

* Good news! On May 16, Google / Nest have announced that while the "Works With Nest" program will end on August 31, 2019, apps like this one will continue working indefinitely, as long as you do not migrate your Nest account onto a Google account. This is a really great news for all of the existing users, as there's now no danger of this app dying on you - and I will do my best to apply to Google's new security screening process, so that the app will also work for the new users, who join after the August 31.

Previous major updates:
* Geofencing support. The app will set your home into Away state (which can set the thermostat into Eco mode) as soon as the phone exits the defined perimeter - and back into Home state when you get back in. You will receive notifications that confirm the Home/Away state has been successfully set, when these events happen. You can set the perimeter to be anything from very small, to several miles in radius. Use this feature if you are for any reason not happy with the similar functionality provided by the main Nest app. Note that if someone else stays at home when you exit the perimeter, your home will soon go back into Home state, when thermostat picks up motion activity inside the home.

* Each of your Nest homes can have one geofence. To set up fences, press the menu button in the top left, and select the option from the menu. Make sure to "Always Allow" location updates, as geofencing won't work otherwise. The app uses your location only to change the Home/Away state, and never sends your location anywhere. You will also be asked if you wish to receive notifications from the app. Notifications are sent to confirm that the Home/Away state has been successfully changed, after you cross the fence perimeter.

Previous major updates:
* The app now displays much bigger and more readable thermostat circle on your iPhone and iPad, which scales down for users with multiple thermostats, to avoid having to scroll unnecessarily. Thermostat circle is also smoothly animated now, as the temperature changes.

* Using Siri voice shortcuts you can now control many aspects of your Nest, such as instant activation of heating or cooling, direct setting of your favorite temperatures, increasing/decreasing the temperature, and setting the Home/Away state. Thanks to Thermo Watch, it's all finally just one casual "Hey Siri" away, all with quick and informative visual and verbal feedback.

* Shortcuts you've created can be used as part of the workflow in the Shortcuts app.

* Thermostats can now be manually re-ordered in the iOS app, and the order will propagate to the iOS Widget, and the Watch app. Just pick and drag them up and down the list.

* New screen sizes on all new iPhones and Watches are supported, as well as all the new complications.

* Accessibility Voiceover feature is now supported in the iOS app.

* Thermostats displayed on the iOS Widget can now be cycled through, by tapping the text on the right side. This way you can access any of your thermostats, while keeping the widget minimized. If you double tap on this text, the official Nest app will open (previously it would open with a single tap).

Great Functionality!

The app is great! The app is very functional and gives me a great status view and control of my two Nest Thermostats! Some of my favorite features are: 1) the iOS widget provides me a fast way to control the temp, home/away status, humidity, and ambient temperature for my upstairs and downstairs thermostats. 2) Apple Watch widget gives me the same control as the iOS widget but it also has a GREAT complication showing me the cool/heat status, on/off status, ambient temperature and humidity. [the Nest Watch app doesn’t have this]. 3) tvOS app also gives me all the above control on my AppleTV [the Nest TV app doesn’t have this-in fact, you can’t control your thermostats on the AppleTV Nest app. It’s only for the Nest Cam].

With all that said, I’ve reached out to the developer a few times to provide suggestions and issues and they have been VERY responsive! I would recommend this to anyone who wants a really cool control and UI for their Nest Thermostats.

Outstanding App and Awesome Developer!

I don't usually write app reviews, but I was really impressed with this app and developer. Clearly a lot of thought and work has gone into this app, and there's a surprising amount that it can do. The Siri shortcuts are amazing!

I initially had an issue with Siri encountering an error when trying to complete this apps shortcuts, but I contacted the developer and got a quick response with some troubleshooting tips, which quickly solved my issue. It turned out to be that my Nest was set to the mixed Heat/Cool mode, which is not supported for Siri Shortcuts (fine by me, I just left it in that mode because I'm lazy). After setting it to Cool via the official Nest app, I was then able to ask Siri to make it two degrees cooler and promptly hear the fan turn on.

Very impressed with the quality of this app, the value for the price (I would have happily paid $9.99 for this app), and the quick developer response. Oh, and I haven't even tried it on my Apple Watch yet, so I'll update here when I do.

If you have any issues, please reach out to the developer, he sorted my small issue and had me up and running in no time!

Watch complication is wonderful

The Thermo Watch app itself is not the focus of this product. The Today View widget and the Apple Watch complication are what truly make this app invaluable for me. Being able to see the current ambient and set temperatures at a glance is so much easier than opening the slow and cumbersome Nest app (especially since I have a bunch cameras and smoke detectors that clutter the interface of Nest’s app). Adjusting the temperature on the watch is also quick and easy. It’s a simple pleasure, but it’s one that Nest itself doesn’t offer, so I’m very thankful for Thermo Watch

Developer Response ,

Thank you for the review. The main focus of the iOS app right now is to enable Siri integration with your Nest. You can go in the app, create Siri shortcuts, and then use Siri to control your Nest, without having to open the app.
