best brown noise app for ADHD focus iPhone buy once no subscription
Sereno has a dedicated ADHD Focus scene — brown noise layered with pink noise and gentle rain — plus a full noise palette and per-layer mixer, all behind a single one-time purchase.
Resposta curta
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.

Comparação rápida
| Necessidade | O que verificar | Porque importa |
|---|---|---|
| Modelo de preços | Verifique se as funcionalidades úteis exigem subscrição, um desbloqueio único, ou nenhum dos dois. | A app mais barata no primeiro dia pode não ser a mais barata ao fim de um ano. |
| Modelo de privacidade | Prefira o processamento no dispositivo quando o conteúdo é sensível. | Documentos privados, currículos, dados de estudo e conteúdos familiares merecem um tratamento cuidadoso. |
| Exportação / dependência | Confirme os formatos de ficheiro, a partilha, as cópias de segurança e os controlos de eliminação. | Uma boa app deve ajudá-lo a concluir a tarefa, não prender o seu trabalho. |

Perguntas frequentes
Is brown noise proven to help ADHD?
Evidence is preliminary and individual. Some small studies suggest background noise may aid focus for some people with ADHD, potentially through stochastic resonance, but there are no large-scale clinical trials confirming brown or pink noise as an ADHD treatment. Many people find it helpful; others find it distracting. Experiment carefully, and consult a professional for ADHD management.
Can I mix and save my own sounds in Sereno?
Yes. The Sereno mixer lets you add multiple sound layers simultaneously — for example, brown noise and a gentle rain layer — adjust each volume independently, and save the result as a custom named scene.
Does Sereno need an internet connection to play sounds?
No. Every sound in Sereno is synthesized in real time on your device. Nothing streams from the internet; Sereno works in full airplane mode.
