This is what the phone sees. QBoss boxes the number, reads it and checks it.

How it works

  • Built for container numbers. QBoss reads each number with OCR and its own AI model, built specifically for containers. The model keeps getting better.
  • Runs on the phone. The reading happens on the device itself, so it works with no signal.
  • Pair it with Watchtower. Bring many phones together in one place. See Watchtower.
  • Did we mention it's free? The app is free on iPhone and Android.

What it does

  • Reads on its own, hands-free once the phone is mounted.
  • Stamps every read with the time and the phone's location, so you know when and where each box was seen.
  • Works with no signal and automatically syncs later.
  • Checks the ISO 6346 check digit on every number that has one. See how the check digit works.
  • Free on iPhone and Android, with no per-container charge.

How a yard check goes

Mount your phone before you move. QBoss works hands‑free, so there's nothing to touch while the truck is moving.

A 500-box yard check: about 2 hours by clipboard, about 16 minutes with QBoss. Try it with your yard.

  1. Mount the phone in the truck.
  2. Drive the rows.
  3. Your list is ready when you park.
