GroceryHubTT — Crowdsourced Grocery Price App

Grocery prices in Trinidad and Tobago change constantly and vary between stores, but there is no easy way to see where an item is cheapest. Shoppers rely on flyers and guesswork.

GroceryHubTT builds a crowd-sourced price database from shoppers' receipts. Point the camera at a receipt and AI reads the store, items, prices and date. Everyone gets the best recent local prices, plus shared grocery lists with budgets.
