App Description

Please Don’t Rain is a fun, convenient way to track whether rain (or snow) will affect a day that’s important to you. Many weather apps are great for seeing the weather for today and for the next several days, but they’re not so great for continuing to keep track of a particular day.

Speaking

I gave my first talk, Don’t Let Time Zones Ruin Your Day (Days?), at Swift Leeds in October 2025. Learn from the mistakes I made when dealing with time zones when developing Please Don’t Rain.

Development

Please Don’t Rain

I’m a SwiftUI hobbyist that focuses on my latest app, Please Don’t Rain. It tracks whether rain (or snow) will affect a day that’s important to you. When I had a theme park day coming up I really only cared about the weather for that day and looking it up over and over again was annoying. Hence an app idea was born! I wanted to learn how to use WeatherKit and this was the perfect opportunity. The app has changed so much since I initially launched it in 2023 and my accessibility support got the app nominated for a 2023 Golden Apple award by AppleVis (which I am very proud of).

Privacy

Sun, 17 Aug 2025 19:09:22 -0500

The developer cares about your privacy. The app does not have any advertising. RevenueCat processes the in-app purchases. The app instructs RevenueCat to use anonymous identifiers that cannot be tied back to you. The app does not store personal information such as name, email, etc. The data you create with the app does not leave the device. The app does not know your location or ask for permission to know your location.
