Continuous playback test

Skip straight to the end of a loop. You no longer need to wait 10 or 20 minutes to test playback on your iPhone.

Ready. Choose a test and tap Play.
This test prefers native HLS on Safari; other browsers use MP3 fallback.
0:00 / 20:00
Drag the slider towards 19:55 to test the end of the 20-minute stream.
Source-loop boundaries passed: 0
Audio starts only after a tap. Seeking may take a moment while Safari buffers the requested segment.

How to test in under a minute

  1. Select Production loop for White Noise, or Green Noise, and press Play.
  2. Tap Jump to 9:55. Listen for 10–15 seconds to check that the sound continues beyond 10:00.
  3. For the quick test, select Quick loop and jump to 19:55. Listen to whether it restarts at the end of the playlist.
  4. You can also lock the iPhone screen before crossing either boundary.

The production HLS stream contains 7 days of audio in its native playlist. This test slider deliberately shows only its first 20 minutes, because the relevant boundaries are at 10:00 and 20:00. The 20-minute quick test is a separate short stream.

This page is for playback QA, not a medical or infant sound-level test. Phone calls and iOS system interruptions may still stop playback. A working seek test does not independently prove reliable overnight lock-screen audio.
