What's New in 40 Below

2.0

April 7, 2026

== What's New in Version 2.0 == Thank you to everyone who has used and provided feedback on 40 Below! It's been a lot of fun building this little app, and there are some really fun additions and improvements in this version. The headliner, though, has to be Siri support! With this update, there is now full Siri and Siri Shortcuts support in 40 Below. That means you can ask Siri, "What's the temperature in 40 Below?" and it will helpfully tell you in both Fahrenheit and Celsius for your current location. This works when you've got AirPods in and when your phone is hooked up to CarPlay! If you ask Siri, "Show me the weather in 40 Below", it will present a beautiful view right on the screen without having to open the app. Additionally, these things are scriptable! The Shortcuts app exposes these features so you can use them in your Shortcuts. 40 Below rarely prompts you for a review, so if you've found it useful and you have the time, a rating or review would be awesome and much appreciated. NEW • Added new Siri Shortcuts and improved action support for Shortcuts and Siri. • Added a Siri forecast card. • Added a daily forecast view alongside the hourly forecast. • Added the ability to email support; check out the About sheet on iOS. IMPROVED • Fixed an issue where the forecast drag handle could respond to taps but not actual dragging. • Improved reliability around location and weather refreshes. • Improved loading behavior so progress stays visible until temperature and location details are fully updated. FIXED • Adjusted App Store links to fix an issue where the App Store was reporting 40 Below as "not available" in certain regions. • Fixed an issue where temperatures might not update correctly after changing locations. • Reduced unhelpful location error messages.

Gorgeous app

What a gorgeous and simple app! Quite often I’m at work on a Zoom and this is the first question “what’s the weather like down there?” Working for a Canadian company as a US citizen I can get close, but am usually off. Love having this at my fingertips. Thanks, team! ❤️
