X-Ray shows an image of a wrist x-ray. The image moves as you move your watch; the flesh, bones and watch buckle pictures move at different rates, giving a 3D (parallax) effect. Demo: https://youtu.be/kytOuCACl-4

Trick your friends by showing them your watch while you’re wearing it. If a friend is in front of you, touch the right side of the screen first: this puts the clockface into ‘friend mode’ which adjusts the position of the image. A red dot will flash in this mode.

X-ray is a well-featured exercise clockface. It displays an activity measure, which you can cycle by touching the left side of the screen. The measure includes percent of daily goal, and the icon fills up as you progress. If you go above 100%, it fills up a second time.

The heart rate reading also gives a percent through the heart rate zone you’re in, and its icon fills and recolors to suit.

On Versa 2, X-Ray has an always-on display mode.

Extensive settings are available.

Cost: $1 USD + tax.
