Support
Questions, bug reports and requests go to one address. I read all of it.
The same address takes privacy requests. If you are testing the beta, feedback sent through TestFlight reaches me too.
For a bug, it helps to know the device, the iOS version, the app’s version and build, and what you were doing. For a sound problem, say which scene was playing and whether you were on speakers or headphones. A rough description is fine.
Common questions
Where do I find the drones?
Start playback with the orb, then tap the Drone card or Tune on the main screen. Choose a scene; Drift is a good first listen. Choosing a scene raises the Drone level if it was off. Reduce the noise levels if you want to hear the drones by themselves.
What do Drift and Hold do?
Scenes gradually vary their mix. Drift travels through Temple, Glass and Vigil over roughly twenty minutes. Hold pauses the scene’s mix changes; it does not freeze the synthesizers or stop the sound. Resume lets the scene continue.
Can I change the mix myself?
Yes. Drag a family’s row to change its level, or tap it to open its detail controls. Adjusting an automated control takes that control out of scene automation. Select the scene again to restart it and hand the controls back.
Why does playback stop when I disconnect headphones?
On iPhone and iPad, Lethe pauses when an audio device disconnects so it does not unexpectedly switch to the built-in speaker. Check your output route before starting playback again.
Can I listen with the screen off?
Yes. Lethe supports background playback and system playback controls. The sleep timer fades the sound out before stopping it.
Does it need an internet connection?
No. Once installed, the app generates its sound on your device. TestFlight installation, updates, and visiting these support pages do require a connection.
Where can I get Lethe?
Lethe is currently in beta testing through Apple’s TestFlight. This site does not yet have a public download link. If you already have an invitation, open TestFlight to install the available build.
Requires iOS or iPadOS 17 or later.
