Bye-bye Carsickness

"Bye-bye Carsickness" is a lightweight utility that helps reduce motion sickness while riding in vehicles.

The app displays a semi-transparent water surface animation as a system overlay around the edges of your screen. This animation responds in real time to your device's motion sensors, creating a gentle visual cue in your peripheral vision that stays synchronized with the vehicle's actual movement.

== Why it works ==
Carsickness is caused by a mismatch between what your eyes see (a static screen) and what your inner ear feels (vehicle motion). By adding a motion-synced visual element to your peripheral vision, this app helps bridge that gap and may reduce discomfort.

== How to use ==
1. Open the app and tap "Start Service."
2. Grant the overlay permission to the app when prompted.
3. Use your phone normally — the water wave effect appears as a subtle border around the screen.
4. The effect automatically responds to your device's tilt and orientation.
5. Tap "Stop Service" or use the notification to turn it off.
