Partly Sunny has been featured in Apple’s “New Apps We Love”, MacStories, AppAdvice, and Lifehacker.

Partly Sunny “introduces a robust, beautiful new way to view weather information.”

“What’s immediately striking about Partly Sunny’s design is that it feels designed to belong in iOS. It’s an app that feels built by Apple if the company decided to make a massive iterative change to its own stock Weather app.”

Jake Underwood, MacStories

“If you are looking for minimalism in your weather app, then Partly Sunny will satisfy your cravings.”

“Partly Sunny offers the information you need in a concise and flexible way.”
