In a series of tweets, iOS developer Steve Troughton-Smith shared his findings surrounding Apple's iOS Simulator running stock apps at the screen size of the purported 5.5-inch iPhone 6, with dimensions of 736 points x 414 points (1472 x 828 at 2x or 2208 x 1242 at 3x). When viewed in landscape, certain default iOS 8 apps, including Calendar, Contacts, and Game Center, display contents in a divided mode very similar to the layout an iPad uses while in landscape.
These findings indicate that the larger, 5.5-inch iPhone 6 could have a stronger focus on productivity than its smaller 4.7- and 4-inch counterparts. Despite apps functioning normally while in portrait mode, this addition of dividing the landscape app view to display two separate menus would introduce a strong motivation for purchasing the 5.5-inch device over its more manageable companion.
