02 The Science · Transit Time

Every other app blames
the wrong meal.

Most reactions fire 12 to 72 hours after the bite. Gutsy is the first tracker built around that.

Your Personal Pace

plate to gone

Every body moves food at its own pace. Gutsy learns yours.

Typical range · 12h–72h+
02 · Journey
Where reactions begin

Food doesn't hit you in the moment. It hits you hours — sometimes days — later.

Most IBS reactions begin in the colon
03 · Attribution
The math no app does

Your 3pm bloat today? Tuesday's dinner.

Retroactive correlation engine · +44h lag

The first trigger engine built around real human transit time.

Not a food diary. Not a FODMAP lookup. A gut-intelligence system.

— A letter for you

IBS. Autoimmune Disease. Anxiety. Insomnia. And I'll just go ahead and say it out loud, depression. A chronic, painful, 15 year cycle. 5 colonoscopies before the age of 30. $25K of my hard earned money trying to figure out why my body was so broken.

All systems have failed me. So we are building our own.

08 FAQ

Common questions.

A food diary asks you to spot patterns. Gutsy finds them. The correlation engine walks symptoms backwards through your personal transit time (typically 12–72 hours) to identify which meal — possibly two days ago — actually caused today's flare.
No. Gutsy is a tracking and intelligence tool, not a medical device. It's designed to make your conversations with a doctor or dietitian more productive — by handing them a one-page clinical-grade report.
Most people start seeing high-confidence triggers around week 3 of the protocol. By week 6 you have a complete personal trigger map, with confidence percentages and recommended reintroduction windows.
Your health logs are stored on your device, and we never sell your data. With your consent, photos and text you send to AI features are analyzed by OpenAI over encrypted connections and not kept afterwards. Usage analytics, including the diagnoses and symptoms you enter during onboarding, go to Mixpanel under a pseudonymous ID. You can export everything at any time.
Full access to everything — AI meal analysis, trigger detection, the 6-Week Protocol, the Gutsy AI coach, doctor-ready exports. You won't be charged until the trial ends, and you can cancel anytime before then.
Yes. The transit-time engine is built around your personal pace — whether that's 12 hours or 72+. All three subtypes run through the same protocol with personalized adjustments.
Yes. Manage and cancel through your Apple ID settings. You'll keep premium access until the end of your billing period. No retention emails. No cancellation maze.
