Mix sounds. Find balance.
A Flutter ambient sound mixer for sleep, focus, meditation, and calm background listening—built for a quick one-tap start and deep control over your mix.
ZenBlend layers rain, nature, urban ambience, meditation tones, child-friendly textures, and more. Audio is engineered for seamless loops (zero-cross trims, short crossfades) and consistent loudness for long sessions. Licensed sources include the Moodist collection (CC0 / Pixabay-style terms where applicable), Pixabay, Mixkit, and similar royalty-free libraries—metadata tracks category, tags, and license in the app's catalog.
Playback uses just_audio with audio_service for background listening. Presets and settings live in local storage (Hive / SharedPreferences). Firebase Analytics and Crashlytics help us improve stability and understand aggregate usage—not to sell your secrets.
We use Google Mobile Ads (AdMob) and may use Firebase Analytics and Crashlytics. Where required, ad consent is managed through UMP and your device settings.
