Start with one sound
Choose rain, ocean, forest, fire or another sound from the collection. Let it play on its own first. This makes it easier to decide whether a second sound adds something useful. For example, a rain track can be the main layer while a quieter forest ambience adds a sense of space.
Balance each track
Sleepi’s mixer has volume control per track. Keep the sound you care about most in front, then reduce any layer that feels distracting. Check the mix on the actual device or speaker you plan to use: a phone speaker and an AirPlay speaker can make the same balance feel different.
Check playback and the timer
The published app supports background playback, AirPlay, and a sleep timer with fade-out. Choose your output device and timer duration before settling in. If you change speakers, check the volume again. Explore current premium requirements in the App Store and in the app; available sounds can change with releases.
