Slumber Studios

What Slumber Studios is

Slumber Studios is a sleep audio company that publishes a family of apps, podcasts, and audiobooks designed to help people fall asleep and stay asleep. Rather than a single platform, it is a collection of separate products: three apps (Slumber, Deep Sleep Sounds, Bedtime Fan), seven podcasts (including Get Sleepy, Sleepy History, The Sleepy Bookshelf, Just Jane, Send Me To Sleep, and Snuggle), a library of 150 or more audiobooks, and original sleep music released on major streaming platforms. Over a million people fall asleep with Slumber Studios content every month across all platforms. The company was formed in April 2019 when two separate sleep audio companies merged: Indian Summer Media (which created the Slumber app in 2016) and Kitefaster (which launched Deep Sleep Sounds in 2016). The core team numbers about twenty people, writers, editors, podcast hosts, musicians, audio engineers, and software engineers, spread across the US, UK, Canada, Germany and beyond, with narrators based in and around London.

The apps and how they work

Slumber, the flagship app, is packed with sleep stories, meditations, soundscapes, and calming music, each made to quiet your mind and guide you gently to sleep using methods backed by the National Sleep Foundation. Deep Sleep Sounds is marketed as the number one white noise app, with every soundscape recorded and mixed by professional audio engineers. The app originated as a way to calm fussy babies but has grown to include sleep sounds for every age, including pet owners. Bedtime Fan is the number one fan sound app, where you pick your fan, add rain or crickets, and mix in soft music to drift off gently. All three apps are free to try on both iPhone and Android. The apps have earned a combined average rating of 4.72 stars from 576,000 total ratings. Together they have been downloaded more than 35.7 million times.

The podcast lineup includes Get Sleepy, described as one of the world's most popular sleep shows, where listeners drift off to bedtime stories. Sleepy History offers true tales and historical narratives. The Sleepy Bookshelf features Elizabeth Grace reading classic novels slowly and softly, books by authors like Jane Austen, Charles Dickens, and Arthur Conan Doyle. Just Jane, launched in August 2026, is Elizabeth Grace reading Jane Austen's complete works, a chapter or two a night. Send Me To Sleep (acquired in August 2022 from another publisher) offers another voice and format for sleep storytelling. Snuggle brings bedtime stories to families with children. The podcasts have accumulated more than 400 million downloads and earn a 4.74 average rating from 16,500 ratings. New episodes are released every week and are always free. The company notes these are not automatically generated or AI-narrated; every voice is a real person, every script passes through human writers and editors, and a human audio engineer mixes every episode.

The Sleepy Bookshelf audiobook library contains over 80 classic novels, works by Austen, Dickens, Doyle and others, read slowly and softly until you drift off. These are free to listen to on the podcast app, and the company also publishes them as audiobooks on major audiobook retailers. Beyond the written-word content, Slumber Studios released an original music catalog created specifically for sleep. The company now functions as both an audiobook publisher and a music label, with original sleep music by seven artists available on Spotify, Apple Music, and every major streaming platform. These composers create slow, spacious tracks designed to fade into the background as you drift off. Three artists are highlighted: Cosmazul, with ambient music from a Los Angeles home studio, has 639,000 monthly listeners; Pajama Llama Lullabies creates gentle lullabies for babies and tired parents with 192,000 monthly listeners; and Moon Garden Ambient offers quiet ambient moods built by the company's own musicians and sound designers with 104,000 monthly listeners. Combined, the sleep music has been streamed more than 200 million times, with more than 10 million monthly streams.

What the platform offers and costs

All three apps are available on iPhone, iPad, and Android devices. All the podcasts are free and available on major podcast platforms. The company operates on a freemium model with a premium subscription option, though the exact pricing is not published on the captured pages. The site mentions a "Premium Subscription" in the footer links, indicating a paid tier exists, but specific pricing for monthly, annual, or lifetime plans is not detailed. You can listen to all seven podcasts for free with new episodes released every week. The audiobook library is accessible free through the podcast apps but also sold separately as audiobooks on major retailers. Free additional sleep tools are available on the website, including a Sleep Calculator, Caffeine Cutoff Calculator, Breathing Pacer, Tonight's Sky (which shows your night sky), and a Moon Phase Calendar.

What the company does not disclose

The captured pages do not specify the pricing for the premium subscription tiers across the three apps, whether pricing differs by app, whether there is a family or group plan, or what specific features are locked behind the paywall versus available free. The site does not list which specific content in each app requires a subscription versus is free. The company does not publish clinical trial data or research comparing its sleep content to other solutions, though it notes the content is "backed by leading sleep groups like the National Sleep Foundation." The pages do not detail the company's refund policy, subscription cancellation process details, or whether users can download content for offline use beyond mentions of offline listening capability in the app descriptions.

Who it fits and who it does not

Slumber Studios works well if you like variety and want to try multiple formats, some nights you might listen to a sleep story, other nights white noise, and some nights a podcast. The breadth of the catalog (seven podcasts, three apps, audiobooks, and music) means there is likely something to match different preferences and moods. It is ideal if you want completely free options; all the podcasts are free and you can explore the apps without paying. If you specifically want human narration over AI-generated voices, the company's emphasis on real people reading scripts is central to its offering. Families with children find Snuggle appealing for bedtime stories for kids.

It is not ideal if you need clinical or therapeutic support, this is entertainment and background audio for sleep, not therapy or medical treatment. If you want a single integrated app covering everything, switching between three apps and seven separate podcasts may feel fragmented compared to a single all-in-one platform. If you need your sleep content personalized to your specific sleep problems or medical conditions, these are general sleep sounds and stories without adaptation to individual needs.
