🌙 Aura Cycles
Sync your cycle. Maximize your aura.

Science-based cycle tracking for when to schedule your Pilates vs. lifting days — and your founder-pitch days vs. your creative vs. admin days. Built for every stage, including perimenopause and menopause, where hormones aren't just cramps and bloating but brain fog, fatigue, and strength. Starting or on a GLP-1? Time your first dose so you begin on a week your stomach and energy are on your side. Enter a couple of period dates and a few details, and Aura Cycles maps your cycle so you know exactly when to push, when to protect, and what to eat for it. Powered by The Aura Engine — fully deterministic, nothing hallucinated. Your data stays in your browser.
