Reintro: FODMAP IBS Tracker

Reintroduction is where most low-FODMAP plans stall. Reintro schedules your
challenges, captures symptoms in seconds, and builds a tolerance map you can
hand to your dietitian.

Built with Phase 2 dietitian guidance — calm, clinical, and explainable. No
streaks, no shame, no diet hype.

— FEATURES —
• Finish reintroduction in 6–8 weeks with a guided 9-group schedule: lactose,
fructose, sorbitol, mannitol, GOS, and the four fructan groups (wheat, onion,
garlic, fruit).
• Track real food triggers, not noise — built-in confounder logging for sleep,
stress, and cycle so a bad night doesn't poison your results.
• Log a dose or symptom in 10 seconds with severity sliders and a Bristol
stool picker.
• Watch your tolerance map form in real time: pass, fail, inconclusive — with
the exact dose days and confounder flags behind every verdict.
• Recover gracefully if you miss a dose: one tap inserts an extra washout and
shifts the schedule forward.
• Share a clinician PDF with your dietitian or doctor — date range, outcomes,
symptom trends, confounder summary.
• Optional Apple Health integration for sleep and cycle data (read-only).
• Calm, capped notifications: morning dose, post-dose check-in, evening
wrap-up. Quiet hours honored.

— HOW IT WORKS —
1. Pick your pace and choose the symptoms you want to track.
2. Follow your daily Challenge Card: today's dose, washout, or rest.
3. Watch your tolerance map fill in. Export a PDF when you meet your
dietitian.

Reintro is for the person already doing the work who just wants the protocol
to make sense. It is not a generic food diary, not a calorie counter, and not
a barcode scanner. It is the tool that gets you through Phase 2 with a result
you can act on.
