DreamTone is a free sleep sound app that lets you MIX multiple sounds together — not just pick one loop.
Why mixing matters: your brain adapts to a single sound fast, but layering 2–5 sounds creates a richer soundscape that lasts all night.
38 sounds across rain, noise, ocean, fire, nature, urban, meditation & binaural beats. Includes 19 presets, sleep tracking, smart alarm, sleep cycle calculator, offline mode, 7 languages, no account/data collection, and no $70/year paywall.
