Blind shoppers can ask an app what's on the shelf. With the apps I reviewed, they still have to check whether the package they picked up is the one they asked for. Similar packaging makes that hard. In one grocery retrieval benchmark, the top open-source model ranked the correct product first 77% of the time (https://arxiv.org/html/2605.18029v1#S5.SS1). Ittro takes its name from the question a shopper asks with the package in hand: "Is this the right one?" Ittro is a voice-first app for a standard Android phone. The shopper asks what's on the shelf and names the product they want. Ittro finds it and guides their hand using spoken directions, audio ticks, and vibration. Once they pick up a package, Ittro reads its label and checks that every requested detail matches before saying yes. When it can't verify a match, it says "I can't confirm yet." The demo is in English, and the app also speaks Arabic and French. During the hackathon, I built the Android app and relay, including the voice workflow, hand guidance, outline tracking, and in-hand verification. The relay calls Meta's models and holds the API key on the server. The dated build log records this work and credits existing tools and prior materials separately.
