Horizon forces you to shoot video in landscape (pictures)

Horizon all but eliminates the possibility of accidentally recording a vertical video by shooting the video in landscape mode no matter how you hold the device.

The first time you launch Horizon, you're greeted with a brief tutorial explaining what each mode found within the app does.

Additional functionality is found in the iPhone app. You can do things such as add filters, adjust recorded frame-rate, and create custom settings.

There's not much to Horizon, aesthetically at least. A viewfinder is placed in the middle of the screen with buttons for settings, recording video or taking pictures, and one to toggle between front- and rear-facing cameras.

As you rotate the device, the viewfinder rotates in the opposite direction. This ensures your video is always recorded in a landscape orientation.

Settings within the app allow you to adjust camera resolution, change the zoom level, and replay the tutorial, to name just a few.
