LithoCanvas is an Android app for people who collect minerals and art. Photograph a rock, gemstone, crystal or painting and it suggests what it is, with typical properties such as hardness, crystal system and luster, or style, medium and era for art. Each find goes into a private collection with your photos, notes and a voice note. No ads, data stored in the EU, 5 identifications included.

Hi Product Hunt. LithoCanvas is for people who collect minerals and art and want both in one private collection. Take a photo of a stone or a painting, the app suggests what it is, and you decide what to keep, with your own notes and a voice note about where the piece came from. For minerals there is a Mohs hardness test, a size estimate with a coin for scale and a glossary of the terms.
The best-known rock identifier on Android turns its 7-day trial into a yearly charge, and most of its one- and two-star reviews are about that. LithoCanvas has no trial: every account gets 5 identifications, and the collection on your phone stays free. No ads, data stored in the EU.
It is Android only for now, in English and German. Tell me what you collect and where the app gets a stone wrong.
