Compatibility Cards is a lifestyle app available on the iPhone platform that helps individuals uncover their intimate match with another person based on their birth dates. Unlike traditional astrology, the Magi System utilized by Compatibility Cards offers a more precise and individualized approach by focusing on birth dates rather than just months. This system, rooted in numerology and developed 25,000 years ago, suggests that individuals sharing the same birth date tend to have similar traits, excluding twins.

Each birth date corresponds to a specific card, with names matching those in a standard playing card deck. The app allows users to determine their planetary birth card match by inputting both their own and another person's birth dates, providing insights such as closeness, compatibility, love, and potential challenges in the relationship.
