More about CycleBalance

About CycleBalance

CycleBalance is an iOS app built around the needs of people with polycystic ovary syndrome (PCOS). While many cycle tracking apps assume a regular 28-day cycle, CycleBalance was designed for the 1 in 10 women whose cycles are irregular, unpredictable, or absent.

The app features irregular cycle intelligence that adapts to cycles ranging from 21 to 90+ days, integrated insulin and glucose tracking for managing insulin resistance, PCOS-specific symptom logging, on-device machine learning via Apple's Core ML framework for finding symptom-lifestyle correlations, and doctor-ready exportable reports. All data is stored and processed entirely on-device with zero cloud sync.

Key Facts

  • Supports irregular cycles from 21 to 90+ days without penalty or false warnings
  • Insulin and glucose tracking integrated with cycle data
  • 100% on-device privacy: no cloud sync, no data selling, no third-party analytics
  • On-device machine learning (Core ML) surfaces symptom-lifestyle correlations
  • Doctor-ready exportable PDF reports for healthcare appointments
