How can we help?

Yes. Lullaby keeps playing in the background, and you can pause or stop it from the lock screen, the notification or your headphones. On some Android phones, aggressive battery saving can stop background audio: open Settings → Apps → Lullaby → Battery and allow unrestricted use.

Up to 5. In Mixes, tap “Create a mix” (or the + in the playback bar), pick your sounds and set each one’s volume, then save the combination as a mix. In the Library, a tap plays a single sound on its own.

Tap Timer in the player and choose 15 minutes to 2 hours, a custom time, or “until I stop it”. When the timer ends, sounds fade out over 45 seconds. You can switch the fade off, or set a default timer that starts with every new mix, in Settings → Playback.

Yes. All sounds are built into the app, so they play without a connection — even in airplane mode.

Keep it soft — around the level of a gentle shower (about 50 dB) — and place the phone at least a metre away from the crib, never inside it. This is general guidance, not medical advice; your paediatrician is the best person to ask about your baby’s sleep.

All 40 sounds and melodies, no ads, and unlimited saved mixes. You can choose a monthly or yearly subscription, or a one-time lifetime unlock.

Open Lullaby, go to Settings and tap “Restore purchases”. Make sure you are signed in with the same Apple ID or Google account you used to buy Premium.

Subscriptions are managed by Apple and Google. On iPhone: Settings → your name → Subscriptions (or apps.apple.com/account/subscriptions). On Android: Google Play → profile → Payments & subscriptions → Subscriptions (or play.google.com/store/account/subscriptions). Cancel at least 24 hours before the renewal date. Deleting the app does not cancel a subscription.

Payments are processed by Apple or Google, so refunds follow their policies. For App Store purchases use reportaproblem.apple.com; for Google Play see Google Play’s refund page. If you’re stuck, email us and we’ll help.

Premium sounds can be unlocked for free for a single play by watching a short video. The unlock lasts until you stop that sound.

No. There is no sign-up and no login. Your settings, favourites and mixes are stored only on your device.

Ads are what keep the app free. They never play sound, so they won’t wake the baby, and they only show family-friendly (G-rated) content. We keep them to a minimum: no full-screen ad appears right after you open the app, or while a sound is playing when you come back to it, and at least three minutes pass between two full-screen ads. With Premium you see no ads at all.

If you are in a region where consent is required (such as the EU/EEA or the UK), open Settings → Privacy options in the app. You can also limit ad tracking on your device: on iPhone, Settings → Privacy & Security → Tracking; on Android, Settings → Privacy → Ads (or Google → Ads) and delete your advertising ID. See our Privacy Policy for details.

Everything the app stores lives on your device, so uninstalling Lullaby deletes it (on Android you can also use Settings → Apps → Lullaby → Storage → Clear storage). We don’t have an account or a server copy to delete. If you have emailed us, ask us and we’ll delete our conversation. More in the Privacy Policy.

Go to Settings → Language and pick one of the 14 languages — or let the app follow your phone’s language.

Please do! Email us the sound that works for your baby and we’ll consider it for a future update.
