About Coly - Gut companion
Coly: Gut Health Living with inflammatory bowel disease means keeping track of a lot - meals, symptoms, energy, stress, and the unpredictable days in between. Coly gives you one calm, private place to log it all, and uses AI to help you notice the patterns that are easy to miss day to day. Whether you're managing Crohn's disease or Ulcerative Colitis, Coly is built to make daily tracking simple enough to actually stick with - and useful enough to change how you show up to your appointments. Track your day in seconds Quick check-ins let you log meals, bowel movements, pain, energy, mood, and flare indicators in just a few taps. No long forms, no friction. Just a fast, gentle way to capture how you're really doing. Spot what triggers your flares Coly's AI analyzes everything you log and surfaces possible patterns and connections over time - like which foods, stress levels, or habits tend to show up before a bad day. These are AI-generated predictions based only on your own data, designed to help you understand your gut, not to diagnose it. Come prepared to your appointments Download a clear, organized report of your tracked history and bring it to your doctor or care team. Instead of trying to remember the last few weeks from memory, you'll walk in with a real picture of what's been going on - and make every appointment count.
