Track the three natural cycles that run from the day you were born. Chart your physical, emotional, and intellectual rhythms, find your peak days, and notice the critical days when a cycle turns. All you need is your date of birth.
Free Biorhythm ToolsThis chart uses the same engine behind our Biorhythm API. Daily readings, multi-day forecasts, critical days, and compatibility, all in one subscription that also covers astrology, numerology, tarot, Human Design, and more, with typed SDKs and a remote MCP server.
Hi, I am Rosie, your guide to the RoxyAPI insight tools.
Ask me to read your birth chart, pull a card, or map your numbers, and I will interpret what it means for you. Unlike most AIs, I never make the numbers up: every reading runs on real, verified calculations. Curious about the API, pricing, or docs instead? Ask me that too.
