My Brother Hit $576 ARR in 1 Week (Without Marketing)
My brother launched a mobile app a week ago. $576 ARR with zero marketing. No ads, no influencers, not even any short form content yet - it was all just App Store Optimization whilst he was fixing some issues... lol
Hey! It's Kristoffer from BuildWithAI here.
My brother launched a new mobile app a week ago.
It already has $576 ARR with zero marketing. ($1728 valuation with a 3x multiplier)

99% of the users came purely from App Store ASO (keyword optimization) while he was busy fixing bugs. Just people searching for exactly what the app does and finding it on the App Store.
The takeaway
Get your app on the App Store as fast as possible.
Seriously. That's it.
Every day your app isn't live is a day you're missing out on organic traffic from people actively searching for what you built. The App Store is a search engine with buyers already holding their credit cards.
Most people overthink the launch. They want the perfect landing page, the perfect screenshots, the perfect onboarding. Meanwhile, someone else ships a simpler version and starts collecting users.
Why ASO works so well
When someone searches on the App Store, they already have intent. They already want a solution. You don't have to convince them they have a problem - they're already looking for the answer.
Compare that to running ads or posting on social media where you're interrupting people who don't care yet. ASO puts you in front of people who are ready to download right now.
The key is picking the right keywords. Think about what your target user would actually type into the search bar. Not what you think sounds cool - what they'd search for.
But getting downloads is only half the battle
I saw a guy on Twitter yesterday with these statistics from his app:


615 active users. But his results? 13 active trials and $22 in revenue.
My brother's app isn't doing anything revolutionary with the product itself. But he copied Cal AI's high-converting onboarding flow and pricing model almost exactly. The psychology behind every screen. The trial structure. The price points. All of it.
When his app gets the same amount of downloads, he'll have around 50 active trials and $600 in revenue. From the exact same amount of traction.
$22 vs $600. Same downloads. The only difference? One person designed their own onboarding and pricing from scratch. The other stole what's already proven to convert.
You don't need to reinvent the wheel. Find an app that's already making millions, study their onboarding and pricing, and copy what works. That's it. The difference between $22 and $600 from the same traffic isn't luck - it's strategy.
Quick ASO tips that actually matter
- App name matters most - include your primary keyword in the app name
- Use all 100 characters in the keyword field. Don't waste a single one
- Don't repeat words - Apple already combines keywords from your name and keyword field
- Study the competition - look at what top apps in your category are ranking for
Happy building! – Kristoffer, BuildWithAI
