Such a simple thing but so helpful. And the app is clean, attractive, and with great functionality. And now it’s on Apple Watch too?!? Yayyyyyy!!!! Thank you!!!!!! ### 5/5 — Like the dual temps *2026-08-29, version 3.12.1* I like to see the temps in both C and F because I am from Europe but live in the U.S. I hope you won’t be adding anything to clutter the window because to me, the simpler the better. I also like that you provide a choice of two different weather sources. ### 5/5 — Celsius & Fahrenheit together!! *2026-08-29, version 3.12.1* Great for a person whose background is in Fahrenheit to compare and learn Celsius. Thank you! ### 5/5 — Cleanest Weather App *2026-08-28, version 3.12.1* This is the cleanest weather app I’ve ever used. It’s a joy to behold and interact with. The only improvement I could see would be a very essential weather radar “window” you could seamlessly view in the app. I have to go to a separate weather app for a glance at a live radar. I’d never go elsewhere if I had that feature in Franz! But regardless, this app is so worth having. Excellent job on this. ### 5/5 — Great App *2026-08-28, version 3.12.1* This is a great app. I travel a lot internationally for work, so being able to see both Fahrenheit and Celsius temperatures is a great tool to have. It’s also very easy to read and everything is right in front of you. I don’t have to go searching for things. Very happy with the app! ### 5/5 — It’s very cool *2026-08-27, version 3.12.1* I like it cause one you can edit the background, two you can see both Fahrenheit and Celsius, and three cause it tells you the wind and rain speed or something. Overall it’s cool ⭐️⭐️⭐️⭐️⭐️ ### 5/5 — Great app! *2026-07-10, version 3.10.0* This is a great app that shows you both Fahrenheit and Celsius together, which is very useful for us Americans living abroad so they can talk about temperatures with non-Americans in a coherent way ### 5/5 — At last! C & F together!!! *2026-07-02* As an expat, I have been wanting an app like this for so long and am overjoyed to find it finally exists. Thank you, Bjorn! (I hope someday you’ll consider also creating an Apple Watch extension for the app because every time I have to use the native weather app on my watch, I find myself missing Franz Fahrenheit! ❤️) **Developer response:** Edit edit: Hi Anne! Yes, I finally added a watch app and extension :) Feel free to share feedback via the Email the Maker button in Settings :) Hi Anne! Thank you for this very nice feedback! Widget is on the top of my to-do list. I hope I get to it in the next 2-3 weeks after I fix some other annoying bugs ### 5/5 — Fahrenheit + Celsius, simultaneously *2026-06-04, version 3.8.2* This app is exactly what I’m looking for. I’m tired of digging through settings to switch and I want to develop an intuition for both temperature units. Clean UI including air quality. 👍🏻 ### 5/5 — The only weather app that I’ve used for years. *2026-05-16, version 3.8.2* Living in a country for the past 25 years that uses metric, this app has helped me adjust from Imperial/US Standard. It has been very freeing. Although I tend to experience the world in metric now, it remains useful and is an essential part of my core iOS app arsenal. ## Frequently asked questions about Franz Fahrenheit & Celsius ### What does Franz Fahrenheit (& Celsius) do?
