Build a Low-FODMAP Vegan Meal Planning App

1. 1

   Get the FODMAP data right or do not ship

   Serving-size thresholds matter enormously in this protocol (a food can be fine at one portion and triggering at another), and your users will fact-check you against the authoritative testing sources. Data rigor, with a dietitian reviewing, is the product's foundation.

2. 2

   Solve protein first

   The niche's defining anxiety is protein without beans; build the tolerable-options library (firm tofu and tempeh at tested portions, specific grains and seeds) into every generated plan with per-day adequacy checks. This one worry answered daily is worth the subscription alone.

3. 3

   Support all three phases

   Elimination plans, a guided reintroduction scheduler with symptom logging, and a personalized long-term mode built from what the user tolerated. Apps that only do elimination abandon users at the protocol's hardest and most important turn.

4. 4

   Learn from symptoms carefully

   Correlating logged symptoms with reintroduced foods helps users see their own patterns; present it as observations to discuss with their clinician, never as diagnosis. That framing is both honest and exactly what dietitians want to see before recommending you.

5. 5

   Make dietitians allies

   FODMAP-trained dietitians constantly struggle with vegan clients; a practitioner view of a client's phase progress (with consent) turns them into a referral channel that no ad spend matches.

6. 6

   Show up where the desperate search happens

   'Low fodmap vegan' recipe searches and IBS community threads are concentrated and underserved; genuinely good free recipes with tested portions are your acquisition engine, and the planner is the conversion.
