I'm a top Dasher with thousands of dashes. This app on Android seizes up and crashes every single night. It's dangerous when it happens while driving. It requires force-stopping the app or rebooting the phone to get it working again. It costs me money when it crashes right after they offer me an order and I can't accept the order in time because it seizes up. My droid is a Motorola Z3 with 4GB ram
