Confidente

Food sensitivity tracking powered by structured meal plans and statistical analysis.

Confidente helps people identify food sensitivities through a scientifically-informed approach — generating structured meal plans that function as controlled experiments, logging symptoms and meals (planned or not), and using statistical modeling to surface ingredient-symptom correlations.

The name combines confidence interval (the statistical concept) and al dente (the food reference). Con-fi-DEN-tay.

Status

Pre-alpha. Active development.

Concept

Traditional elimination diets are hard to follow and produce unreliable results because they rely on strict compliance and informal pattern recognition. Confidente treats food sensitivity testing as an experiment:

• Meal plans are generated using Latin square-inspired design to ensure controlled ingredient exposure
• “Cheats” and off-plan meals are just additional data points, not failures
• Symptom scores are weighted against daily control variables (sleep, stress, etc.)
• A hypothesis engine detects sensitivity category patterns (histamine, FODMAPs, salicylates, oxalates, etc.) and suggests additional foods to test
• Statistical modeling correlates ingredient exposure to symptom outcomes over time

Tech Stack

• Rails 8.1 / Ruby 3.4
• PostgreSQL
• Hotwire (Turbo + Stimulus) + Tailwind CSS
• Propshaft asset pipeline
• Solid Queue / Solid Cache / Solid Cable (database-backed)
• PWA (progressive web app) → Hotwire Native (planned)
• Kamal for deployment

External Integrations

• Open Food Facts — barcode scanning and ingredient lookup
• Spoonacular or Edamam — recipe pool for meal plan generation
• Apple HealthKit / Google Health Connect — sleep, activity, and biometric data (planned)
• Clue API — menstrual cycle tracking as confounder (planned)

Getting Started

bundle install
rails db:create db:migrate
bin/dev

Requires PostgreSQL running locally.
