The Gap

Generic health apps weren't built for you.

Fitness trackers count steps. Symptom diaries treat Crohn's like a stomachache. Neither knows the difference between ileocolonic and pancolonic disease, neither understands what a nighttime bathroom trip actually signals, and neither makes your next GI appointment any less of a guessing game.

Pain point

Can't track what matters.

BM consistency on the Bristol scale. Urgency, blood, nighttime trips, ostomy output volume. The things your gastroenterologist actually asks about — none of which fit in a generic mood tracker.

Pain point

Medication is life-or-death.

Missing a biologic isn't like skipping a multivitamin. Yet most apps treat Humira, prednisone, and a fish-oil capsule with the same gentle reminder. Different drugs need different urgency.

Pain point

Doctor appointments are a guess.

"How have things been the last six weeks?" I think… worse? You deserve to walk into your GI appointment with real numbers, real patterns, and questions you've already prepared.

The Solution

Gavia changes that.

Seven tracking categories built around the actual mechanics of IBD — bowel movements, pain, nutrition, medications, recovery, physical activity, and mental health. Plus three intelligence systems that turn what you log into something your doctor can use.

Comprehensive tracking

Six dedicated categories — pain, nutrition, bowel movements, medications, recovery, and physical activity. Each modeled on what gastroenterologists actually ask about.

Streamlined meal logging

Log meals in seconds with a 200+ IBD-relevant food database. Track macros and five critical micronutrients — Iron, B12, Vitamin D, Calcium, Zinc. Correlate post-meal symptoms automatically.

Mind & mental health

Daily mood and stress tracking, plus validated PHQ-9 depression and GAD-7 anxiety screenings — validated self-monitoring instruments used in clinical research. If scores indicate distress, Gavia detects your region and surfaces your local crisis helpline — 988 in the US, Samaritans in the UK, Lifeline in Australia, and 16+ countries supported.

Daily check-ins

Guided morning and evening check-ins capture sleep, pain, medications, fatigue, and mood in under two minutes. Build streaks. Catch patterns your memory would miss.

Medication intelligence

Three priority tiers — Critical (Humira, biologics), High (prednisone, mesalamine), Normal (supplements). Adherence calendar. Local reminders that fire offline.

Flare mode

One tap. Hydration goals auto-increase. Safe foods bubble to the top of nutrition logging. Trigger warnings appear. The app reshapes itself around how you actually need it.

AI health reports

Biweekly summaries with real numbers and prepared questions. Three specialist agents cross-check each finding before it reaches you. Math, not guesses.

GutGuide AI

A conversational companion that knows your diagnosis, current medications, and tracking history. De-identified before processing. Not stored by the AI provider.

How it works

From download to doctor-ready in three steps.

01

Tell us about your IBD.

A 9-screen onboarding captures your diagnosis type, disease location, symptom baselines, current medications from a 20-drug database, and a validated mental health screening — no typing essays, no guesswork. Every question is optional except the ones that matter.

02

Track your days.

Designed for flare days first. Three taps to log a BM. Ten seconds to log a meal. Local notifications fire on time even without Wi-Fi. Your data stays on your device.

03

See the patterns.

Biweekly AI reports surface trigger correlations, flare warnings, and prepared questions. Walk into your GI appointment with a one-page summary your doctor can scan in 30 seconds.

The Gavia Standard
You should not have to guess how your last two weeks went. You should walk into your doctor's office with real numbers, real patterns, and real questions — because your condition is serious enough to demand serious tools.
Every feature in Gavia is built to that standard. Offline reliability. Clinical-grade tracking. Answers backed by data, not memory.

Pricing

Free to track. Pro to thrive.

Tracking is a right — every symptom logger, check-in, reminder, and the full Learn library is included in the free tier. Pro adds the intelligence layer when you need it.

Who Gavia is for

Three patients. One companion.

User profiles we designed for — not customer testimonials.

The Newly Diagnosed

Within their first year of diagnosis. Looking for structure and education — what is a flare, what's a normal BM, what should they ask their doctor next visit. Gavia's tailored onboarding and the 21-article Learn library give them a starting point.

Composite profile — not a real user testimonial

The Experienced Patient

Years of living with IBD. Needs depth, granularity, and a tool that respects their knowledge. Streamlined meal logging, trigger correlations, biweekly reports, and a medication library that already knows the difference between Humira and Stelara.

The Flare Survivor

In or recovering from a flare. Needs speed and compassion. Two-minute morning and evening check-ins capture the essentials even on the worst days. Flare diet mode prioritizes safe foods automatically. No tutorial popups. No upsell prompts. Just the bare minimum, available at the worst possible moment.
