  1. 5/5Exactly what I want in a weather app

    I work with folks world wide. The vast majority of them are international and hence don’t depend on “freedom units” for things like temperature or distance. This gives me both F and C temps in one well designed view. Will be donating money via Venmo because this app will help me as a typical uneducated American learn a little bit more about this tiny rock near the sun we call Earth before I expire all too soon. Thanks so much =)

  2. 5/5Need to fix it on the widget

    Weather data unavailable on the widget it is not working on the widget. Set the settings correct but doesn’t work. PS: I'd like to update my rating to 5 stars. I know you're doing your best to improve/fix the app. I recently moved to the USA, and this app has been incredibly helpful for my day-to-day activities. I love that it includes both Fahrenheit and Celsius in all the temperature sections! Thank you!

  3. 5/5Exactly what I was looking for!

    As an American living in the UK, I find myself struggling to discuss the most common topic of conversation here: the weather. Without knowledge of why on Earth the British are complaining about 30 degree weather being HOT, I have become socially inept. I’ve been trying to learn Celsius conversions from Fahrenheit but have been generally clueless. Finding this app was a blessing. It’s so nicely designed, with several different widgets so I can always see the two temperatures. The UI is beautiful, even changing with the weather like Apple’s does. This all combined with the fact that it’s free, with no subscription or anything has endeared this app to me forever. Thank you Franz! I can finally join the people of this country in complaining about the weather, regardless of what it is.

  4. 5/5My favorite weather app in iOS

    I used this app for a long while and it's amazing. It lets you see a "rest of the world" temperature while being able to tell the weather to your US friends. Sadly Apple charges for something they get for free: Weather API access. This means Franz has to charge for something and they chose one of the features I used most which is the widget. There's no option for lifetime, only subscription is available and I'm against subscriptions. I'll keep the 5 stars because the app is still amazing and this issue is Apple's fault, not Franz's.

  5. 5/5The Most Convenient and User-Friendly Weather App

    I’ve recently moved to the U.S. and am still getting used to the local weather conditions. Sometimes it’s challenging to interpret temperatures, especially due to differences in measurement scales, so I’ve been using this app for about a year. It has become an essential tool for me: everything is clear, straightforward, and without unnecessary features—just what I need. Recently, the app introduced a paid subscription, and I understand that all work deserves compensation. Given how useful this app is, I believe the subscription is worth it—especially since it’s not very expensive. Thank you so much to the developer!  I’ve also taken an interest in other apps by this developer and will definitely try them out. Everything is designed simply, clearly, without excess, and is very helpful. Thanks again!
