What you get

Everything Halcyra does well

Focus arcs, not playlists

Each session builds for 12 minutes, holds for 20 and eases out over 8, so the end of a block feels natural.

Reads your calendar

A meeting in 25 minutes? Halcyra shortens the arc and fades out two minutes before you need to talk.

Heart-rate aware

Paired with your watch, tempo drops 4 bpm at a time when your pulse runs high during a session.

Night mode that means it

After 22:00 every soundscape loses its high end and drifts toward brown noise over thirty minutes.

Offline, all of it

Soundscapes are generated on device. Flights, trains and cabins in the woods all work.
