Short answer
Sereno's ADHD Focus scene layers brown noise at moderate volume, pink noise at lower volume, and a gentle rain bed to create a layered background texture that some people find reduces distraction without adding new interruptions. The full noise library includes six colours — white, pink, brown, blue, violet, and grey — all of which can be played individually or blended in the mixer. You can stack any combination, adjust each layer's volume independently, and save your own custom mix as a named scene for next time. The science around coloured noise and ADHD focus is mixed and genuinely individual: some people find it significantly helpful, others find it distracting — Sereno gives you a wide range to experiment with without a subscription. One Pro purchase covers everything. Note: Sereno is not a medical tool and is not a substitute for professional ADHD assessment or treatment.
Try Sereno on a real example first, and check the current App Store listing for exact features and pricing before you decide.

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. |
