SyncMate

Your Privacy-First Period Companion

Adaptive Cycle Prediction

SyncMate learns your unique rhythm over time, refining its predictions based on the patterns you log. The more you track, the smarter it gets — delivering personalized forecasts that fit your body, not a statistical average.

Phase-Based Wellness

Your cycle has six distinct phases, and SyncMate surfaces 30+ tailored suggestions for each one — from energy-matched workouts to mood-aligned nutrition tips. Guidance that changes as your cycle does, keeping recommendations relevant every day.

Privacy-First Design

All your data lives exclusively on your device. SyncMate never syncs to the cloud, never shares with third parties, and requires no account or sign-in. Your cycle data is yours alone — always private, always local.
