The iPhone tool for discovering which stars and planets rise and set along any alignment, today and thousands of years ago. Reveal celestial connections hidden in ancient monuments, sacred sites... or your own backyard. WHAT IS COSMIC COMPASS? Point your iPhone along any structure: a temple axis, stone circle, pyramid edge, or garden wall. Cosmic Compass records the precise bearing using GPS, compass, and camera. Then it calculates which stars and planets rise or set along that line, and when they did so throughout history. Our ancestors aligned their monuments to the stars to mark sacred times, using the sky as an eternal calendar that would never fail them. Discover if that Neolithic monument aligns with Sirius. Find which star rose along a Maya temple axis in 900 AD. Reveal whether ancient builders oriented structures to capture Venus at dawn. Or discover which stars rise along your own street. A JOURNEY THROUGH TIME Calculate stellar and planetary positions from 3000 BC to present, all the way op to the year 3000 AD. Studying a Maya pyramid built in 800 AD? Set the observation year and see exactly where Sirius, Venus, or the Pleiades rose when the temple was new. Capture a line of sight from your house, set the date to the future and save any upcoming alignment to your calendar. You won't miss a thing. This matters because stars shift position over millennia. Precession slowly wobbles Earth's axis, causing star positions to drift about 1° every 72 years. Sirius rose at a different azimuth in 2500 BC than today. Cosmic Compass uses the IAU 2006 precession model for accuracy across 5,000 years. Planets shift too, but differently. Venus, Mars, Jupiter, Saturn, Mercury, and the Moon wander against the fixed stars. The app calculates planetary positions using VSOP87 theory, the same algorithms used by professional observatories. THE MOON'S SECRET CYCLE Every 18.6 years, the Moon reaches extreme rising and setting positions, the lunar standstills. Ancient cultures from Scotland to New Mexico built monuments aligned to these rare events. Cosmic Compass detects lunar standstill alignments, revealing connections that occur only twice per generation. HOW IT WORKS Point your iPhone at any alignment. Tap to capture. The app stores your bearing with GPS coordinates and a photo. Results appear instantly: stars and planets that rise or set along your line, ranked by precision. "Celestial Convergence" reveals when both a star and planet share the same alignment. Calculations deliver sub-arcminute accuracy, more precise than your iPhone's sensors. We recommend calibrating your compass and capturing away from metal interference.

Extremely well executed and makes calculations a breeze! Highly recommended! ## Frequently asked questions about My Cosmic Compass ### 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. ## Version history (last 1 release) ### 1.0 — 2025-12-10 No release notes. ## More apps by Adventuring B.V. - [My Solar Compass](https://appshunter.io/ios/app/my-solar-compass/id6755783690) - [Bible Verse by Date](https://appshunter.io/ios/app/bible-verse-by-date/id6756485345) - [Bee Vision](https://appshunter.io/ios/app/bee-vision/id6756632028) All apps by Adventuring B.V.: https://appshunter.io/developer/1856290988 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
