We're currently rolling out a new feature that allows you to share your crystal collection with other people in a simple and privacy conscious way.
If the other user has Crystal Guide® Pocket Edition then you can just give them your unique share code and they can add you to the app as a friend. They can then see your full collection list, plus all the usual profile data (your personal notes are not shared).
If the other user doesn't have the app (or you want to share to social media), then you can simply share a weblink to your collection by pressing the share button in the app.
An example share is: https://share.markstevens.co.uk/view.php?code=YDHOCNRTAA
To try the Sharing & Friends feature you will need to update to v3.23 or greater and then head over to the 'My Collection' section in the app.
Please post and questions or bug reports in this thread.
Hope you enjoy, all the best, the dev team.
