Sorto is the first email intelligence app built entirely on Apple Intelligence — the on-device Foundation Model. Every email is read, classified, and ranked on your device. Nothing you write or receive ever leaves your iPhone, iPad, or Mac. BUILT FOR IPHONE, IPAD, AND MAC Sorto adapts to every screen. On iPhone, a fast tab-based layout built for one-handed use. On iPad and Mac, a full sidebar with live category counts so you can navigate your entire inbox at a glance.
