About this app

What would your face look like if it were perfectly symmetrical?

Bob takes one portrait and builds two new faces from it: one made of your left half and its mirror, one made of your right half and its mirror. Nobody's face is symmetrical, and the two results are often surprisingly different from each other, and from you.

HOW IT WORKS
• Take a photo with the built-in viewfinder, or pick one from your gallery.
• Bob detects the face and places the symmetry axis for you.
• See the left mirror, the right mirror and the original, side by side.
• Fine-tune the result: move the axis, tilt the angle, change the margin.
• Save one mirror, or all three photos at once: as separate files or as a photo booth strip, vertical or horizontal.
• Share the result with any app on your phone.

PRIVATE BY DESIGN
• Everything happens on your phone. Face detection runs on the device.
• No image, identifier or usage statistic is ever sent anywhere.
• No account, no ads, no analytics, no tracker.
• Exported images carry no metadata from the original photo, GPS location included.

FACE SYMMETRY, FROM THE FIRST SHOT
A framing guide in the viewfinder shows where the face and the symmetry axis should sit, and short tips help you get an even, well-lit portrait: the secret of a convincing symmetric face.

Every feature is free. If you enjoy the app you can support its development with an optional donation; nothing is reserved for donors.
