Take quality horizontal photos and videos while holding your phone vertically!
Just tap the camera mode icon to switch between regular camera mode and ViewFndr Mode. Shoot 4:3, 16:9, and Square photos, and widescreen 16:9 video in either mode.
All important controls are on the main camera screen, so you rarely have to open a settings screen.
What about vertical images and videos? You can take them too in either mode.
Have trouble framing your photo in low light? Just turn on 'spotlight' and see your subject as you frame the shot.
ViewFndr is simple, and versatile!
For iPhone 5s and newer.
