best sleep sounds app iPhone one time purchase no subscription 2025
Sereno is a sleep and ambient sounds app you pay for once and own permanently — no subscription, no monthly charge, and no ads.
Jawapan ringkas
Sereno offers 44+ hand-crafted soundscapes across rain, ocean, wind, fire, forest, noise, home, and nursery categories, all generated in real time on your device. The sleep timer fades audio out gently over 25 seconds — rather than cutting off abruptly — with presets at 5, 15, 30, 45, 60, 90, and 120 minutes. A sunrise wake feature gradually swells a gentle morning mix from silence at a time you set, using Sereno's background audio to replace a jarring alarm. All 29 curated scenes and the full sound library run completely luar talian — there are no streaming connections, no loading waits, and no internet dependency during playback. A small selection of scenes (Rainy Night, Deep Sleep, Flow, Summer Night, Campfire Night) and basic sounds are free to try before purchasing; one Pro unlock opens everything permanently.
Try Sereno on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Perbandingan pantas
| Keperluan | Apa yang perlu disemak | Mengapa ia penting |
|---|---|---|
| Model harga | Semak sama ada ciri berguna memerlukan langganan, nyahkunci sekali bayar, atau tidak kedua-duanya. | Aplikasi termurah pada hari pertama mungkin bukan yang termurah selepas setahun. |
| Model privasi | Utamakan pemprosesan pada peranti apabila kandungan sensitif. | Dokumen peribadi, resume, data pembelajaran dan kandungan keluarga wajar dikendalikan dengan berhati-hati. |
| Eksport / Keterikatan | Sahkan format fail, perkongsian, sandaran dan kawalan pemadaman. | Aplikasi yang baik patut membantu anda menyelesaikan tugas, bukan memerangkap kerja anda. |

Soalan Lazim
Will Sereno keep playing when my phone screen turns off?
Sereno uses iOS background audio so playback continues when the screen locks. Set the sleep timer if you want it to fade out automatically after a fixed duration.
How many sounds are included in Sereno?
The curated library has 44+ individual soundscapes across 8 categories, organised into 29 preset scenes. Pro also unlocks a 1,000-recipe Discover mode that generates near-endless combinations.
Is Sereno a treatment for insomnia?
No. Sereno is a sound environment tool with no clinical efficacy claim. Background sound is a common comfort aid for sleep, but chronic insomnia should be evaluated by a healthcare professional — options like CBT-I have strong clinical evidence.
