THE ISOLAIT FAMILY

One on-device engine. Two ways to make sound work for you.

Isolait started with one problem: pulling a single voice out of a noisy room, entirely on the phone, no server involved. Building that engine taught us something else — the same technology could turn overwhelming sound down, not just isolate it. Today the Isolait family is two apps, one shared on-device foundation, each built for a different relationship with sound.

Not sure? Both are free to download, so try them side by side. For a student in a noisy classroom, see which app to try first. Sensory Comfort is a sound-comfort tool only, not a medical device. It does not diagnose, treat, cure, prevent or manage any medical condition, including autism, ADHD, hyperacusis, misophonia or tinnitus.
