Beat Tap: Studio Stack
Tap to the rhythm of each beat to stack bars of a freestyle — every perfect tap drops a new line and the verses stack to become a track that earns money passively.
Tap in time with beat markers as they pass a target zone; each successful tap adds a verse bar, the completed track idles offline and earns cash.
One-thumb: tap the screen on the beat, hold for sustained bars.
