Zenka: Sleep & Focus Sounds

Zenka is a calm sound mixer for sleep, focus, meditation, and quiet daily routines. Build your own soundscape from white noise, rain, water, fan, nature, home, city, travel, and ambient sounds, then keep it playing in the background while you rest or work.

Use Zenka to:
- Layer multiple sounds and control each volume separately
- Browse sounds by category and keep favorites close
- Start ready-made Relax mixes for sleep, study, meditation, travel, and calm breaks
- Save your own mixes and return to them quickly
- Use sleep timers, slow start, and gentle fade controls
- Import personal audio files with Premium access
- Restore purchases anytime from Settings or the Premium screen

Free users can listen to included free sounds and may watch a short muted rewarded ad for temporary Premium sound access. Rewarded access lasts 12 hours and can be earned at most once every 24 hours.

Premium unlocks premium sounds, premium Relax mixes, more saved mixes, imported audio, and monthly, yearly, or lifetime access options through the App Store.

Zenka does not record microphone audio. Imported audio is selected by you and used only for local playback.
