Spark is one of the best email apps available for iOS and Android. It has received a major new redesign today with a dark mode, customizable email actions, avatars and more.

The new design is much modern and cleaner looking than the older one. It also supports the native dark modes in iOS 13, iPadOS 13 and Android 10. Despite the design change, the app still looks familiar when using, and also has the same blazing-fast email sync and loading performance as before. The app's interface might be too white for some users, as the blue accents are gone for good, but this is where the new dark mode helps.
