Builders demand an open, accurate, free nutrition database and mobile app after MFP paywalls its data

OpenNutrition's HN launch got 311 points with the top comment 'I wish there was an app to analyse my meals from pictures and estimate the calories/macros.' Multiple builders launched MFP alternatives in 2025-2026. The demand is for an accurate, privacy-respecting, free food logging app with barcode and photo scanning.

Product Idea from this Signal

A mobile app and API that gives developers and consumers verified nutrition data with no paywalled barcode scanning

4001.4k โ–ฒ

MyFitnessPal's decision to paywall barcode scanning in 2022 exposed a structural gap: there is no clean, developer-friendly nutrition database that is both accurate and free to query at scale. The USDA FoodData Central API exists but is aging and cumbersome; Open Food Facts is community-maintained with quality inconsistencies. A verified nutrition database exposed as a modern REST API, with a consumer mobile app as proof of capability, gives developers a paid data layer while giving end users a genuinely free calorie tracker.
