FAQ

What is My Cosmic Compass?

My Cosmic Compass is an iPhone tool that helps you discover celestial alignments. It uses your device's sensors to identify which stars and planets rise or set along a specific line of sight, both in the present and throughout history.

How accurate are My Cosmic Compass calculations?

Calculations deliver sub-arcminute accuracy, which is more precise than your iPhone's sensors. The app uses the IAU 2006 precession model for star positions and VSOP87 theory for planetary positions.

Can I use My Cosmic Compass to study ancient monuments?

Yes, you can point your iPhone at any structure like a temple axis or stone circle. The app will then calculate which stars and planets aligned with that structure at specific historical dates.

What historical periods does My Cosmic Compass cover?

The app can calculate stellar and planetary positions from 3000 BC up to the year 3000 AD. This allows you to see celestial alignments as they were when ancient structures were built.

Does My Cosmic Compass have ads?

No, My Cosmic Compass does not contain advertisements. It is a paid application designed for a focused user experience.

What devices is My Cosmic Compass available on?

My Cosmic Compass is currently available for iPhone devices. It requires iOS 16.0 or later.

How does My Cosmic Compass handle lunar standstills?

The app detects lunar standstill alignments, which are rare events occurring every 18.6 years when the Moon reaches extreme rising and setting positions. This helps reveal ancient alignments tied to these cycles.

What is the price of My Cosmic Compass?

My Cosmic Compass is available for a one-time purchase of $6.99. This grants you full access to all its features and historical calculation capabilities.
