About this app

Qin is a private, beautifully designed tracker for your gut and bladder. Log your bowel movements and urination daily, understand your body's patterns over time, and build a clear picture of your habits.

Built for everyone — whether you're recovering from Whipple surgery, managing IBS, IBD, Crohn's, a UTI, kidney issues, or simply want to stay on top of your digestive and urinary habits. Track yourself, family members, multiple patients, or even your pet — all from one app, privately, without an account, and without your data ever leaving your device.

DETAILED LOGGING
• Bowel movements — Bristol Stool Scale (types 1–8), color, size, symptoms, food notes
• Enzyme tracking — log whether you took your digestive enzymes and see how they correlate with your symptoms over time
• Urination — color (Armstrong hydration scale), smell, volume, and symptoms like burning or urgency
• Quick-log in one tap, or go detailed when it matters
• Add notes, flag entries, and edit or delete anything
