Questions
Frequently asked questions
Quick answers about the Heed app. For the technique itself — what ATT is, where it comes from, what the research says — see the science page.
Do I need headphones to use Heed?
Yes — sessions place their sounds around you with spatial audio, which needs headphones to work. Any stereo headphones or earbuds are fine; no special hardware is required.
Is Heed free?
Heed is free to download and comes with sessions included. A premium subscription — or a one-time lifetime purchase — unlocks the full scene library.
Which devices does Heed run on?
Heed is currently an iPhone app.
Does Heed work offline?
Yes. All sounds ship inside the app and sessions are generated on your device, so you can practice without a connection.
Do I have to look at the screen during a session?
No. The practice is done with your eyes open and your gaze resting on any fixed point — a spot on the wall works. The voice tells you everything you need to hear, so there is nothing you need to watch.
How is a session structured?
That has a page of its own: see what happens in an ATT session.
Where do the sounds come from?
Heed ships with a catalog of around a hundred sounds. A session either draws a fresh Random Mix from that catalog, or plays one of the hand-crafted scenes — soundscapes like a campfire at night or a busy kitchen — with each sound placed at its own point in space.
Is Heed therapy or a medical treatment?
No. Heed is a self-practice tool inspired by ATT research — not therapy, and not a medical device. If you are dealing with a health concern, please talk to a qualified professional.
Is Heed affiliated with Adrian Wells or the MCT Institute?
No. Heed is an independent app by SK95 Engineering, built around the published attention-training paradigm of Wells (1990). It is not affiliated with, or endorsed by, Adrian Wells, the MCT Institute, or any clinical organization — and it is deliberately faithful to the published protocol, with every scientific claim on this site cited to a named source.
