Tuck

A baby monitor that fits in your pocket.

Two iPhones become a real-time monitor with AI lullabies in a voice your baby knows — yours, your partner's, or grandma's. Cry alerts, sleep diary, and a Bluetooth-first design that works on flights and off-grid weekends.

Early access. iOS only. No spam, ever.

Nothing to buy. Nothing to wire.

Reuse the iPhone you already have. Set it up in the nursery in 30 seconds. No camera, no hub, no monthly subscription required to monitor.

Lullabies in a voice your baby loves.

Tuck composes new, personalized lullabies in your voice — or a family member's. Different every night, calmly looped, gently faded.

Cry alerts that wake you, not the neighborhood.

Smart alerts learn your baby's patterns over the first few nights. You hear them when it matters; you sleep through the rest.

Works anywhere. Even in airplane mode.

A custom Bluetooth Coded PHY link keeps the monitor running without Wi-Fi or cellular — on planes, in cabins, on long road trips.

A sleep diary you'll actually read.

Two-line summaries of last night, every morning. No charts you'll ignore; no metrics you don't need.

How it works

  1. Open Tuck on your iPhone. Sign in with Apple.
  2. Place a second iPhone in the nursery. Scan a QR code to pair.
  3. Watch live, hear cry alerts, and play personalized lullabies — anywhere.

Common questions

Do I need two iPhones?

Yes — one stays with you, one stays in the nursery. Any iPhone running iOS 17 or later works as the nursery device, including older models you'd otherwise retire.

Does it work without Wi-Fi?

Yes. Tuck falls back to a custom Bluetooth Coded PHY link when Wi-Fi isn't available — designed for travel, hotel rooms, cabins, and flights. Audio and a degraded video stream both pass over Bluetooth.

Is this a medical device?

No. Tuck is a connected baby monitor — it does not diagnose or detect medical conditions and is not a substitute for adult supervision. We do not make claims about preventing or detecting SIDS or breathing irregularities.

How is voice cloning handled?

Voice cloning is opt-in and per-family. You record a consenting family member's voice; Tuck generates lullabies from it. Voice models are scoped to your account and can be deleted at any time.

When does Tuck launch?

We're targeting an iOS launch in 2026. Sign up above to be among the first to get early access — beta testers get free Pro for the first year.

Important: Tuck is not a medical device. It does not diagnose, monitor, or treat any medical condition, and it is not a substitute for adult supervision of your baby.

Tuck uses third-party AI services to generate lullabies and scene descriptions. Audio and video used for these features may be processed in the cloud. You will be asked to consent to this when first using AI features.
