The build
Generative ambient audio and a focus timer. Streams nothing — every layer is synthesised on device, so it works on a plane and costs no data.
Nightshift Radio synthesises its soundbeds rather than streaming loops. Rain, valve hum, distant traffic and tape hiss are each a small generator mixed live through Oboe, which means no repetition to notice and no bandwidth to spend.
The engineering constraint is battery. A full eight-hour overnight session had to cost less than a podcast would, so the mixer drops to a reduced generator set when the screen is off and hands the render loop a larger buffer.
Shipped in 2021 and still on a release cadence — it is the title that convinced us that staying with an app for years is more interesting than launching a new one every quarter.
