Niche Sleep-Sounds App

What It Is

You build a simple sleep-sounds app with AI for one clearly defined group, such as parents getting a newborn to sleep, night-shift workers sleeping by day, or people who fall asleep to birdsong. A few sounds are free, and users pay a subscription for more sounds or longer playback. You research demand by looking at which 'sleep sounds for...' videos get millions of views on YouTube.

The Pitch

Luna says the big app Better Sleep is estimated at about $2 million a month and that Rain Sleep Sounds, built by a solo developer, is estimated at around $500,000 a month despite being 'basically rain sounds on a loop'. She says the problem comes back every night, so people keep paying.

Who It’s Best For

Patient builders who can pick a narrow audience and keep marketing an app for months.

The Truth (as we see it)

Those revenue figures are outside estimates for established apps, as Luna says herself; she also notes elsewhere that only about 20% of new subscription apps make $1,000 in their first two years. You'll need sound files you have the rights to, and app-store fees cut into income. Luna sells her paid AI Profit Lab membership in the video. She also offers a free app-idea checker.
