App design concept for a fictional business, created by Alden Chappell as a portfolio sample. Not a real app.

Ember & Tortilla app

Regulars open it to see where the taco truck is today, get a ping when it opens nearby, order ahead for the pickup window and fill a punch card.

    What it does

    • Answers "where's the truck?" Today's stop sits in one fixed place, with hours, the line and directions, instead of under yesterday's posts.
    • Pings regulars who want it. Switch on the stops you care about, and only hear about the ones near you.
    • Skips the line. Pick a pickup window, see when it's on the grill and when it's ready at the window.
    • Keeps the punch card. App orders punch automatically, and walk-ups get punched with a code.

    Built to stay small

    Five screens around two habits: finding the truck and picking up dinner. The owner updates today's stop from a phone in under a minute.

    It starts as an installable web app: scan the QR on the truck and save it to the home screen, no download. The same screens can ship to iOS and Android later if enough regulars use it.

    Orders, payments and tips stay in the truck's existing POS (Square or Toast). The app never sees card details.
