In converting to Windows 8 the first thing to go from the iPad app is the "chrome" - the navigation bar, pagination controls and the bottom control bar, resulting in a less cluttered application surface. In the Windows 8 version, they are gone but are less necessary because the navigation hierarchy is flattened.

For example, the hub screen for the iPad app shows a single photo for each of the 12 months, with a tab to switch to comments about the photos.

In the Windows 8 version the hub screen is a single month with a featured large photo for the month with other, smaller photos from that month displayed next to it. About a third of the same screen is devoted to comments. For more comments, tap (it's designed for touchscreen) the Recent Comment header. For more pictures, tap the This Month header.

A second navigation alternative involves pinch to zoom - making a pinching gesture while touching the screen to pull out hierarchically from a single photo to sets of 12 squares or tiles, each set representing a different year. Users can, for instance, go from a photo from March 2012 to a photo from July 2010 by pinching the March photo, zooming out to the sets of tiles, tapping the one for July 2010 and sorting through the photos that are brought up. There is no navigation bar.

With the iPad app, the same transition calls for tapping a Years button on the navigation bar at the top of the screen, selecting the year as it appears in a popover box and then sorting through that year.
