WhatMyFoodCostThePlanet

Scan a grocery item and instantly see the water footprint, the region it came from, and whether that region is under water stress like Egypt's Nile Delta — plus lower-impact swaps you can actually find nearby.

Target user

environmentally conscious grocery shoppers who want provenance beyond 'organic' labels

Features
  • Barcode scan that surfaces water footprint and growing-region water-stress score
  • 'Lower-impact swap' suggestions tuned to what your local store actually stocks
  • Personal weekly tracker showing water saved by swaps you adopted
  • Regional explainers ('why this avocado's aquifer is dropping') for the items you buy most
Why now

Egypt's New Delta project and similar megaprojects make water-for-food news mainstream; consumers increasingly hear '95% of Egyptians live on the Nile' and want to know what their own groceries are demanding.

Signals · overall 6/10
Demand
5/10

Multiple existing apps in this exact space (TraceSprout, TraceLess, Scan2Sustain, Ecolink) show real consumer pull, and Innova reports rising demand for water/ocean usage claims, but the source HN trend had only 36 points/2 comments indicating niche not mainstream interest.TraceSprout - Apps on Google PlaySustainability Trends in the US and Canada - Innova Market Insights

Whitespace
5/10

Crowded with direct competitors: TraceSprout scans barcodes for water usage, bitekit is a dedicated food water-footprint calculator with swap suggestions, TraceLess offers eco-friendly swap suggestions — the regional water-stress (WRI Aqueduct) angle is the only meaningful differentiator and is thin.Food Water Footprint Calculator - Liters per Meal - bitekit.appTraceSprout - Apps on Google PlayTraceLess — Mindful Swaps. Smaller Footprint.

Monetization
4/10

Sustainability scanning apps (TraceSprout, bitekit, Scan2Sustain) appear free with no public pricing or subscription, and Innova notes consumers are 'wary' of overuse of sustainability claims — limited evidence of willingness to pay for water-specific data on top of existing carbon-focused apps.TraceSprout - Apps on Google PlaySustainability Trends in the US and Canada - Innova Market Insights

Longevity
8/10

Water scarcity is a secular, climate-driven trend; EU Green Deal and corporate water-disclosure rules are pushing water footprint into mainstream labels, and megaprojects like Egypt's New Delta keep water-for-food in the news cycle.Subdimensions matter: Consumer preferences for water footprint - ScienceDirectWater Footprint Network

Feasibility
7/10

Building blocks exist and are free: Open Food Facts (barcode → product), Water Footprint Network (per-product water data), WRI Aqueduct (regional water stress). The hard part is mapping a packaged product to its specific basin of origin, which requires proprietary supply-chain data not publicly available.Interactive tools - Water Footprint NetworkScan2Sustain | Devpost
