The Transportation Security Administration (TSA) spent a little over $1.4 million on an app that randomly shows a right or left arrow.

The “randomizer” app itself cost $336,000, the rest of the funds most likely went towards iPads themselves, Rare reports. There were four bids total for the project and IBM won the project.

The app’s purpose is to eliminate potential bias when a TSA agent tells passengers which line to go to. Currently on the iTunes app store, there are multiple free coin flip apps which perform the same process as the TSA’s “randomizer.”
