Operating from the United Kingdom, The Citrine Circle has developed a complimentary mobile application that functions as a comprehensive reference tool for more than four hundred varieties of crystals and minerals. This digital platform assists enthusiasts in managing their personal collections while expanding their understanding of geological specimens. Through the application, users have the ability to explore available options either through alphabetical listings or visual galleries. The search functionality enables filtering by origin country, with additional refined criteria available for more precise queries. Every individual crystal profile includes foundational details alongside a specialized Geological section encompassing composition data, durability measurements, color ranges, structural classification, streak characteristics, optical properties, and significant source localities. Additionally, a Metaphysical section provides insights into spiritual attributes, corresponding energy centers, zodiac alignments, elemental connections, numerical significance, and planetary relationships associated with each specimen.

This application also features entertaining educational games, comprising four distinct quiz formats designed to enhance user learning, alongside a Memory Pairs game utilizing the stunning crystal imagery. Rather than serving as a reference tool for crystal identification, the primary purpose of this application is to support users in developing their knowledge about individual crystals. The collection does not claim to be comprehensive or definitive, and the development team continuously works to incorporate new content, refine existing material, and expand the application's offerings to maximize its educational value for users.

This mobile application was developed by the married couple behind The Citrine Circle, an enterprise they established and currently manage. Their dedication to crystals and learning drives continuous improvements to the app, including additional crystal entries and informative content. The mobile version serves as a convenient companion to their website rather than a substitute, offering users access to essential information in a compact format. The application can be downloaded at no cost and is accessible to users across the globe.
