How do I make my own sound? Drag across the bars to paint a spectrum. Left is low frequencies, right is high. Tap Save to keep it under My Sounds.
Can I rename or delete a saved sound? Touch and hold it.
Will it keep playing with the screen locked? Yes. Use the lock screen or Control Center to pause, or set the sleep timer (the moon button) to fade out and stop.
What does Swell do? It slowly raises and lowers the volume, like waves. Depth sets how far it dips; Period sets how long one rise and fall takes.
