About CycleBalance
CycleBalance is the first iOS app built specifically for people with polycystic ovary syndrome (PCOS). While most cycle tracking apps assume a regular 28-day cycle, CycleBalance was designed from the ground up 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.
