Real monthly searches are just the starting point. We estimate the total demand is about 8× bigger once you include related searches, app store browsing, and word-of-mouth. From that pool, a small new app captures a slice based on ad competition — then some visitors sign up free and a fraction decide to pay. The numbers above are the upside case if the product gets real distribution; not a guarantee.

Point at a listing, get recent sold comps across the usual marketplaces, and a plain verdict: good deal, fair, overpriced. Mobile.

Unit-price scanner for grocery runs

Simple mobile app: scan two shelf tags, it normalizes to price per 100g/ml and tells me which is cheaper. Offline-first, no accounts. I want it clean and fast — under 2 seconds per scan.
