How Can We Help?

Contact Us

If you're experiencing issues, have feature requests, or need help with the app, please reach out to us at . We typically respond within 48 hours.

How accurate are the planetary positions?
Cosmic Kronos uses the Swiss Ephemeris, the same astronomical engine used by professional astrology software. Planetary positions are accurate to arc-second precision for dates spanning thousands of years.
Do I need my exact birth time?
For the basic natal chart showing planetary signs and aspects, an approximate time works fine. However, for accurate house placements and your rising sign, you'll need a birth time precise to within a few minutes. Check your birth certificate or ask family members.
How does the "Find Similar" feature work?
You choose a reference chart (any date and time), set a search range, and select your matching criteria. The app scans planetary positions across your chosen time window and returns dates with the highest similarity scores based on planetary positions, aspects, or both.
Is Cosmic Kronos available on both iOS and Android?
Yes. Cosmic Kronos is available on the Apple App Store and Google Play Store.
I found a bug or have a feature suggestion.
We'd love to hear from you. Please email with a description of the issue or your idea. If reporting a bug, include your device model and OS version to help us investigate.
