EndoGlow is a symptom tracker designed to help people with endometriosis and cycle-related pain understand what their body may be trying to show them over time. Instead of trying to remember everything at your next appointment, EndoGlow gives you one place to log pain, energy, mood, symptoms, bleeding, and daily notes in a way that feels simple, supportive, and useful. As your history grows, EndoGlow helps turn those entries into clearer patterns, timelines, and summaries you can actually use. With EndoGlow, you can: • Track pain, fatigue, mood, bleeding, and symptoms day by day • Notice how symptoms shift across your cycle over time • Log flares, triggers, relief methods, and daily context • View trend snapshots that make symptom history easier to understand • Build doctor-ready summaries from your tracked history • Export clearer information for care conversations • Unlock deeper insights and recurring pattern detection with EndoGlow Plus EndoGlow was built for people who are tired of second-guessing their symptoms, forgetting important details, or walking into appointments without a clear picture of what has been happening. The goal is not more overwhelming health data. The goal is clearer self-understanding, better reflection, and more confident care conversations. EndoGlow does not provide medical advice, diagnosis, or treatment. It is intended for informational and educational purposes only and should be used alongside professional medical care.

HONEST PREDICTIONS • Next period date with a prediction window, not a false exact day. • Fertile window and estimated ovulation day. • Current cycle phase and a plain-language confidence level. • Irregular cycles and late periods are explained, never silently guessed away.
