Understand Your Four Phases
Your cycle isn't just "period or not." It's a rhythm of four distinct phases, each with its own strengths, challenges, and opportunities.
Guidance First. Not Just Tracking.
Most period apps make you log data without telling you what to do with it. PeriodGuide is different. We lead with actionable, evidence-based guidance for every day of your cycle, then let you track to refine that guidance over time.
