Ambience and Nature * Layer dynamic ambience and nature sounds. * Remix programs, combining them to create multi-stage ambient and nature programs, and reuse them across different Stacks.

Color Noise * Layer a color noise element into your stack for sound masking and tinnitus relief. Pure Sine Waves * Create pure sine waves from 100 to 1000 Hz with power equalization and 2-decimal precision. * Remix and combine programs to create multi-stage Solfeggio progressions.

On price, rating, in-app purchases and monetization model there is nothing between them.
