How a Simple Sleep Sound App Makes $50K/Month
I came across Bedtime Fan, a simple sleep sound app that helps people relax and fall asleep by playing realistic fan and white-noise sounds.
Maker: Slumber Studios
Revenue: $50K/month
Marketing Strategy
1. App Store Optimization (ASO)
The app targets high-volume keywords like "white noise," "sleep sounds" to capture people already searching for solutions to sleep better.
2. Cross-Promotion
Slumber Studios has a broader ecosystem of sleep apps and bedtime content. They can use their existing audience to drive users toward Bedtime Fan.
The lesson?
Sleep is a real problem and people are willing to pay for solutions.
What makes this interesting is that you don't need to build one complicated sleep app with hundreds of features.
You can take one successful concept and expand it into different niches:
→ White noise
→ Green noise
→ Brown noise
→ Gray noise
→ Rain sounds
→ Fan sounds
The core technology can be very similar. You are simply targeting a different user intent and keyword.
This is why I think sleep sound apps are an interesting mobile app opportunity. You don't always need a new idea. Sometimes you just need to find another niche for an idea that already works.
If you're looking for more validated mobile app ideas with their estimated MRR and marketing strategies, I put together a list you can check out here.
love the part that from one idea it is possible to build multiple part.
first make one successful then you can diversify into ultiple niches.
cool idea
thanks
Thanks for sharing the idea
it's my pleasure
Sleep is a real pain and i think the idea has huge potentiality
yeah sleep is a real pain and it's greatly rewarded if you can solve it.
simple but useful app.
yeah useful app
It's a very good idea. I am gonna try it out. I need your help building it.
I am glad that your are gonna try it out.
How do you know their revenue? And I bet, it's not a simple app. And one more point: even if it's "simple", the distribution is not.
the revenue is verified from sensor tower.
Your idea is really good but few of us will get success.
yeah because only few people stick to an idea for a long time
Love the idea that from one codebase it is poossible to expand into multiple niche
that's the fun part
so true
who knows that a sound app would print that amount of money
it's mindblowing
Thanks for sharing. great idea.
i am glad that you like the idea
New concept i learn today.
yeah
50k/month from a sound app. there is a huge demand,
thats why it is making that much money
that's mind blowing!
exactly
I will try it relaxation app
sure.
I am glad that your are gonna try it out. nice and can you customize ?
yeah you can customize
nice and can you customize or edit any sounds?
yeah, you can.
But people are already listening to music on YouTube to fall asleep. Why would they come to your app?
It's not my app but people are not only listening they are paying $50k/month for the sleep sound. you tell me why they are paying rather than listening to youtube?
The interesting part to me is how little the core product actually needs to change. People search for very specific sounds, so creating separate apps around those intents could make ASO much easier. It’s a good example of how a simple product can still have room to grow if the distribution and positioning are right.
exactly
That's really goo idea
thanks
amazing concept
yeah
When mimicking what another app already does, what steps do you take to differentiate yourself?
Why do you need to differenciate. For consumer apps everyone is focusing on UGC nowadays. Just focus on SEO and get a decent users, make money and be happy.
i love the idea, but i hate the idea of having your phone on to have to relax. it feels a bit contradictory
ok
