1. Choose Save It for food, or Ruin It for something questionable.
2. Pick an ingredient and hit Add to the Sandwich.
3. Drag sideways to rotate, or vertically to tilt between −60° and +60°. The arrow buttons do the same. Zoom and pan are locked. Every added layer has a label with its ingredient, number and time; tap a label or choose a layer from the list to inspect it.
4. Share a layer’s permanent link with a friend, or download its image.

One shared sandwich, growing one real contribution at a time. Each browser can add one layer per UTC day; the allowance resets at 00:00 UTC.

See where everyone is adding from. Your approximate city and country are public by default; choose Country only or Keep it private before adding. We never request GPS. When a coarse location is unavailable, your layer can still be added. Removing your layer hides its content and public link, while its numbered place and today’s allowance remain.

This hides your contribution and location from the sandwich and its public link. Your numbered place is preserved, and you can add another layer after 00:00 UTC.
