The app offers several key features:

1. Concert Mode: Sync your penlight with performance data via Bluetooth to enjoy various lighting effects during concerts. This feature is exclusive for concert use.

2. Bluetooth Connection: Switch to "Bluetooth Mode" by pressing the penlight button for 3 seconds. Enable Bluetooth on your smartphone and bring it close to sync with the penlight.
