Every major cycle tracking app on the market assumes a 28-day cycle. If your period is irregular, late, or unpredictable, you get red warnings, confused predictions, and features that simply don't apply. We built CycleBalance because the 1 in 10 women with PCOS deserve a tracker that works with their biology, not against it.
Polycystic ovary syndrome disrupts the hormonal signals that drive ovulation, which means cycles can range anywhere from 21 days to several months. Tracking these patterns over time is one of the most powerful things you can do to understand your body and have more productive conversations with your doctor.
Most health apps upload your most intimate data to cloud servers, where it can be sold, subpoenaed, or breached. In a post-Dobbs world, reproductive health data carries real legal risk. CycleBalance takes a different approach: all your data stays on your device, processed locally, and never touches our servers.
