The First App I Ever Built Makes $25K/Month

Kyan, a 21-year-old CS student at San Diego State, built ToneAdapt, a web and iOS app that tells guitarists how to set up their own gear to sound like any song. Vibe-coded V1 in a week over Thanksgiving break; ~5 months later it has 100K+ users and ~$25K in the last 4 weeks (~$11.5K web via Stripe, ~$14K from an iOS app launched a month earlier). Growth came from founder-led short videos posted 3x a day across Instagram, TikTok, YouTube and Facebook, then scaling winning formats with remakes, UGC creators and paid ads.

Pick a problem from your own hobby, then ask others in Reddit and Instagram comments

Many guitarists had the same problem and no real fix existed

“I realized I was using ChatGPT at the time to figure out how to get guitar tones, but it wasn't really all that accurate. And I talked to other guitarists on Reddit, on Instagram, mainly in comment sections, and many of them had the exact same problem, but there was no real solution out there.”

Launch a paid web version in a week, then build the iPhone app later

iOS app made ~$14K with 397 subscribers in its first month

“You can ship a web app today and get someone to pay for your products by tonight if you ship on the internet. Don't spend hours picking a logo, don't polish anything, just build something, put it on the internet, and charge money for it.”
