Hey! Show your destination to taxi driver

You can use Hey! app when you show your destination to the taxi driver.
Or when you want to show your address without digital communication.
It also work as digital signboard when you greet a guest at the airport.

Hey! is a simple app that only one single functionality that is to show enlarged characters.

It can do a single task but also many of doesn't:
- It won't rotate even your device moved. It help you when you use Hey! in unstable situation such as inside taxi cab.
- Nothing happen even you tap on the screen. Taxi driver need to hold a steering wheel, so they may "grab" your phone. If you use web browser to show destination, their finger tap something then your intended page is gone.
- Hey!'s screen won't go anywhere by tapping screen. It goes off when you tap "close" button which appear AFTER you swipe the cover bar at the bottom of the screen.
- Hey won't go sleep mode. Even the driver is busy for a while, you can just wait. No waste of time to unlock the device from sleep mode.
