I turned a simple habit tracker into a 15k MRR business. Sebastian Rohl always wanted to build his own apps. So he decided to quit his job and give himself 12 months to figure it out. No plan, no idea, just a dream to build. I quit my job with no idea, just 12 months of runway. But six months in, he had less than a dozen downloads on his app, and he was faced with a decision. He changed up his strategy and then found an idea that changed everything. And then in under two years, he went from just building side projects that made him a few hundred bucks to a full-time solo developer making 15k a month on the app store. The secret to reaching top 10 in the app store is... In this video, I bring Sebastian onto the channel to break down what happened after he quit his job and it's not what you'd expect. We'll also go over his failed ideas and why they didn't work. And he'll share the secret to why his app has been downloaded over 300k times. This is the Playbook to Building Successful Apps. I'm Pat Walls, and this is Starter Story.
