CostCast: Catch Shrinkflation Instantly - Scan a price tag — see price per kg, lb, or oz instantly

Packages shrink, prices don't drop — shrinkflation makes "deals" look cheap until you check the unit price. CostCast reads any grocery price tag with your camera and shows price per kg, lb, or oz instantly — fully offline and on-device. No typing, no account, no data leaving your phone.

Hey PH! 👋 I built CostCast after noticing how often "cheaper" packs at the store are actually more expensive per kg once you do the math — brands shrink the package, keep the price, and most people (me included) never check. How it works: point your camera at any price tag, CostCast reads the price and weight/volume on-device, and shows you price per kg, lb, or oz in real time — works with metric and imperial units. No typing, no photo upload, no account — everything runs offline, right on your phone. Built this solo, would love your feedback — especially on which currencies/regions to prioritize next.
