Short answer
A dedicated ADHD-focus scene blends brown noise, pink noise and gentle rain at calibrated levels to cover background chatter, and a custom mixer lets you dial in the exact blend that keeps you on task. Different brains need different mixes — the control is the point.
It's pay-once, so you can use it for every work session without a recurring fee.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
