Stone Keeper support

Stone Keeper is a private collection for geological finds. Save photos, notes, and the place where you found or stored a specimen.

Photo comparison is experimental. Version 1.0 compares photos with references for calcite, chalcopyrite, fluorite, granite, and marble. It tries to suggest useful visual matches, but can be wrong, show several alternatives, or leave a find unidentified. A suggestion is never a definitive identification.

For better suggestions, photograph one specimen in daylight and add a whole view and a close-up. You can always save and organize a find without identifying it.

Send feedback

Ideas, questions, and bug reports are welcome. Contact Mats Amlie at matsamlie@gmail.com, or choose Send feedback at the top of Settings in the app.

The app opens Apple's email composer when Mail is configured. Otherwise, it offers to open an email app or copy the contact address. Only the recipient and subject are filled in: the app does not automatically add a message body, photos, collection records, notes, logs, or other app data. You choose what to write and whether to send. Keep photos or details out of the email if you would rather leave them only on your device.

The app cannot confirm that an email has reached the recipient. If a message appears in your email app's Outbox, check its sending status there.

Feedback received by email is used to reply to you and improve Stone Keeper. The email itself is deleted no later than 90 days after the case is closed. Read the privacy policy for details.
