What is Gemmia
Gemmia is a diamond-mosaic app. Each cell shows a number that maps to a colored gem — place the stones one by one and a sparkling, textured picture builds up out of tiny gems.

What makes it special
Turn a photo into a diamond mosaic and place the coloured stones one by one on the real grid.
The shared picture of the day has “Invite everyone”; private rooms open by invitation link, and a room supports up to 10 people.
There is a picture of the day with daily records and a visit streak.
After the first online start, the app keeps its shell, catalogue and saved work offline; shared rooms and syncing still need internet.
