99 cents, no subscription, does exactly what you need. The anti-subscription baby app.
Baby Sleep Apps
White Noise Baby by TMSOFT costs $0.99. Once. No subscription, no premium tier, no upsell. 20 built-in sounds (white noise, pink noise, fan, womb, heartbeat, rain), 10 lullabies, cry detection, and access to 10,000+ community sounds via White Noise Market. If you just need background noise for the nursery and refuse to pay monthly for it, this is the one.
300+ soundscapes with 10 frequency sliders each. Made by a PhD in signal processing. No subscription ever.
Baby Sleep Apps
Not a baby app at all - it's an audio nerd's sound generator that parents discovered. Each soundscape has 10 sliders to tune individual frequencies. Womb sounds, rain variations, fan hum - calibrated to your actual hearing profile. One-time $15-20 to unlock everything. No ads, no subscription, no AI, works offline. If you just want to hit play and go to bed, this is way too much. If you're the parent who returned three white noise machines because they "didn't sound right" - welcome home.
Baby monitor that tracks sleep with computer vision - no wearable on your baby.
Baby Sleep Apps
Companion app for the Nanit camera ($150-300). Watches your baby sleep and analyzes duration, quality, and patterns using computer vision - nothing strapped to their wrist or chest. Live HD video, two-way audio, temperature, humidity, white noise built in. Free: live view and basic alerts. Insights ($100/yr) adds sleep analytics, video history, milestones. Expensive stack - camera plus subscription. But if sleep data matters to you more than price, Nanit's analytics are in a different league from Huckleberry or any software-only tracker.
The app half of Owlet's smart sock - tracks your baby's pulse and oxygen while they sleep.
Baby Sleep Apps
Owlet Dream is the companion app for Owlet hardware. Without a Dream Sock ($299) or Dream Sight camera ($99), the app does nothing. With the sock, you get live pulse rate, blood oxygen, and sleep stage tracking on your phone. The optional Owlet360 subscription ($9.99/mo) adds deeper analytics. Expensive peace of mind - but parents who buy it tend to swear by it.
Wake window calculator that actually adjusts to your specific baby - not just age charts.
Baby Sleep Apps
Napper predicts nap and bedtime based on your baby's real sleep data, not generic tables. Free version is basically a timer. Paid unlocks the good stuff - adaptive schedule, 30+ white noise sounds, sleep articles, trend charts. $49.99/yr after a 7-day trial. If you just want wake windows without the full tracker overhead of [Huckleberry](/huckleberry), this is lighter and faster.
Sleep stories and meditations for kids 0-12 - they fall asleep 28 minutes faster. Not a white noise app.
Baby Sleep Apps
Original characters, sleep stories, lullabies, guided meditations, mindfulness games - 1,000+ pieces of audio content. For kids who've outgrown shushing sounds and need a story to wind down. Parents can disable games at bedtime with Play Schedule. Works offline via Bluetooth - press play, leave the room. $59.99/yr or $9.99/mo. Up to 3 devices. Zero screen time needed. If your kid is under 6 months, white noise apps like Baby Shusher work better. Moshi shines with toddlers and up.
200+ sounds you can layer and mix yourself - the sleep app for parents who hate presets.
Baby Sleep Apps
Not a baby app. It's a sleep app that parents discovered works great for nurseries. White noise, rain, heartbeat, womb sounds, binaural beats - each with its own volume slider so you build your own mix. $60/yr after 7-day trial. Has a baby-specific mode with volume limiting for little ears. If mixing 8 sound layers feels like overkill, Baby Shusher does one sound for $4.99 forever.
Cry detection that auto-plays white noise before you even wake up. The 3am hero.
Baby Sleep Apps
Sound Sleeper listens for crying and automatically starts playing soothing sounds - no parent intervention needed. Age-specific sound libraries: womb and hairdryer for newborns, fan and rain for infants, ocean for toddlers. The cry detection is the killer feature. Pricing is messy (multiple tiers from $7 one-time to $40/yr), but the lifetime unlock at ~$20 is the move.
Remote control for your Hatch Rest - change sounds and light without opening the door.
Baby Sleep Apps
Useless without a Hatch Rest device ($70-130). But if one's already in your nursery - you control everything from the couch: sounds, colors, brightness, bedtime schedules. Build a multi-step routine (dim light, white noise on, auto-off). The "OK-to-wake" green light actually trains toddlers to stay in bed. Membership ($70/yr) adds sleep stories and meditations - nice but not essential. The hardware is the real product here.
The sleep course every parent group recommends - expensive but it actually works.
Baby Sleep AppsParenting Courses & Education
Taking Cara Babies is not an app. It's a set of online video courses by Cara Dumaplin, a neonatal nurse with 25+ years of experience. The newborn course (~$99) covers 0-12 weeks. ABCs of Sleep ($179) tackles 5-24 months. One-time purchase, lifetime access, 30-day money-back guarantee. Not cheap. But when you haven't slept in weeks and need a structured plan, this is what most parents reach for.
Predicts your baby's ideal nap time - and parents say it's spookily accurate.
Baby Sleep AppsBaby Tracking & Milestone Apps
SweetSpot tells you the exact window for the next nap based on your baby's patterns. Free tier tracks sleep, feeds, diapers, growth. Plus ($59/yr) adds predictions and schedule builder. Premium ($130/yr) adds expert sleep plans with weekly check-ins. 14-day trial, no card. If sleep is the thing keeping you up (literally) - start here. If you need broader tracking across many caregivers, Baby Connect covers more ground.
