Raynaud's Attack Logger (Blood Flow Disorder Tracker)

Raynaud's phenomenon is a condition where blood vessels in the fingers, toes, and sometimes other extremities constrict excessively in response to cold temperatures or stress, causing the affected areas to turn white, blue, and then red while experiencing numbness, pain, and tingling that can last from minutes to hours. Approximately 5 to 10% of the general population experiences Raynaud's, with higher rates among women and people living in colder climates, and while primary Raynaud's is often manageable, secondary Raynaud's can signal serious underlying autoimmune conditions requiring careful monitoring. Currently, no dedicated apps exist to help Raynaud's sufferers track attack frequency, duration, severity, and triggers, or to monitor whether lifestyle changes, medications, or warming strategies are actually working, leaving patients without data to optimize their management strategies or provide useful information to their doctors.

People need an app that logs each attack with details about trigger exposure (cold temperature, stress, specific activities), tracks which fingers or toes are affected and the color changes observed, records pain levels and duration, monitors the effectiveness of warming techniques and medications, correlates attacks with weather data, and identifies patterns that help predict and prevent future episodes.

This represents a strong business opportunity because the market includes millions of sufferers who experience frequent attacks that disrupt daily life and work, the community is accessible through online support groups and social media, patients are motivated to pay for solutions that reduce painful and embarrassing episodes, the condition requires long-term management creating subscription potential, and growing awareness of Raynaud's as a legitimate medical condition rather than just "being cold" is expanding the market of people seeking dedicated management tools.
