Built by a Crohn's patient who gets it. Fathom is the AI companion that helps you track symptoms, spot patterns, and find better days.
Between doctor visits, you're managing IBD on your own.
You might notice that certain foods affect how you feel. You have questions at 2am when you just need someone to talk to. Living with IBD is deeply personal, and it's hard to explain the daily adjustments and uncertainty.
Meet Fathom.
Built by a founder living with Crohn's disease, Fathom is a wellness companion that learns your unique needs. It helps you organize the knowledge scattered across your memory and notes into one personalized space.
Key Features:
- Smart Tracking: Log bowel movements, meals, and symptoms to spot patterns.
- AI Companion: Chat 24/7 to figure out meals, manage stress, or just feel heard.
- Daily Check-ins: Simple start and end-of-day logs to track how you’re feeling.
- Weekly Insights: Get a personal snapshot of your wellness journey every week.
Fathom is a judgment-free zone. Over time, you'll move from guessing to knowing what works for your body.
Fathom Pro offers deeper support with a personalized AI that truly learns who you are, smarter meal tracking, and revenue contributions to IBD research.
Available for free or upgrade to unlock the full power of Fathom Pro.
