Sadly, the employees apparently shuffle things around for local reasons and the app doesn't get updated. The employees will then badmouth the app to customers (well, one customer, at least...). "Oh, the app? Yeah, that's wrong a lot... We actually put that item over there at the end of that other aisle, because we wanted to put other-item here instead."

If the robot is using the same DB it will have the same problem. If it's using a different DB the app should be switched to that DB.

Or maybe the robot should walk the aisles and scan all bar codes to make the DB for both

Personally I don't want to install an app, I just want to visit a mobile webpage.
