Quick answers for everyday Lull questions: building mixes, the sleep timer, custom covers, and restoring a Pro purchase.
支持页面
整理了 Lull 日常使用中的常见问题:如何编排混音、睡眠定时器、自定义封面,以及恢复 Pro 购买。
How the app is laid out
The home screen shows eight scene cards. Tap one to enter the mix screen. On the mix screen, each row is a sound — drag the slider to adjust its volume; tap the play / pause button to start or stop the whole mix. The "+ Add a sound" button at the bottom opens the full library (Pro). The clock icon opens the sleep timer.
界面结构
主页显示八个场景卡片。点击其中之一进入混音页。 在混音页里,每一行是一种声音 —— 拖动滑块调整音量; 点击播放 / 暂停按钮开始或停止整个混音。 底部的「+ Add a sound」按钮可打开完整声音库(需 Pro)。 时钟图标用于打开睡眠定时器。
Custom mixes
- Open the library, tap + next to any sound, choose "Create a new mix" or "Add to current mix".
- When creating a new mix, give it a name and optionally pick a cover photo from your library.
- You can swipe left on a sound row in the mix to delete it. Default-scene stems are locked (volume only) — user-added stems are fully editable.
- From Settings, swipe left on a saved mix to delete it, or tap "More" for the same actions.
自定义混音
- 打开声音库,点击任一声音旁边的 +,选择「新建混音」或「加入当前混音」。
- 新建混音时可以给它命名,并可选地从相册中选择一张封面照片。
- 在混音页中可以左滑某行声音将其删除。预设场景里的声音是锁定的(仅能调音量),你自己添加的声音可完全编辑。
- 在设置中,可左滑保存的混音将其删除,或点击「更多」执行相同操作。
Falling asleep with Lull
Tap the clock icon at the bottom of the mix screen and choose a duration. The mix plays at full volume until the last 90 seconds, then fades gradually to silence — so it doesn't wake you when it ends. Cancel from the same sheet to clear the timer.
用 Lull 入睡
点击混音页底部的时钟图标,选择时长。 混音会一直以正常音量播放,直到最后 90 秒开始缓缓淡出至静音 —— 结束时不会把你吵醒。再次打开同一面板可取消定时器。
Restoring a purchase
If you reinstall the app, switch devices, or sign into a new iCloud account that has previously bought Lull Pro, open the paywall (tap any locked scene or the library lock) and tap Restore purchase at the bottom. Lull asks StoreKit to re-verify your entitlement and unlocks Pro if your Apple Account already owns it. No re-payment.
恢复购买
如果你重装了应用、更换了设备,或使用之前购买过 Lull Pro 的新 iCloud 账号登录, 请打开付费页面(点击任意锁定的场景或声音库锁图标), 然后在底部点击「Restore purchase」。 Lull 会向 StoreKit 重新核验你的权益,若你的 Apple 账号已拥有该购买, 则会自动解锁 Pro。无需再次付款。
FAQ
Does it play in the background? Yes. Audio continues with the screen off, from the lock screen, and from Control Center.
Does it need an internet connection? No. All sounds are bundled in the app. Lull never makes network calls during playback.
Why is one scene free but the others locked? Rainy Library is intentionally free so you can try the app's core feel before committing. Pro is a one-time payment — no subscription.
Can I import my own audio? Not yet. The current version plays only the 66 hand-curated bundled sounds.
Will my saved mixes survive an app reinstall? Saved mixes live in iOS app storage. Reinstalling clears them unless iOS app data is restored from a device backup.
FAQ
能后台播放吗? 可以。关屏后、锁屏与控制中心都能继续播放。
需要联网吗? 不需要。所有声音都内置在应用内,播放过程中 Lull 从不发起任何网络请求。
为什么只有一个场景免费,其余都锁定? Rainy Library 故意保留为免费,这样你可以先体验应用核心质感再决定是否购买。Pro 是一次性付费,不是订阅。
能导入自己的音频吗? 当前版本尚不支持。目前只播放内置的 66 种精选声音。
重装后保存的混音还在吗? 保存的混音存放在 iOS 应用存储中。重装会清除这些数据,除非从设备备份中恢复。
