In their words
I Built Two Apps That Make $120K/Month
Pat WallsWalk me through like the actual like timeline of that. Like how long did it take to get to the place where someone actually paid money?
Kyle FowlerI started building in winter of 2019, and so then I finished it and gave a Reddit update post about having completed it, and then so I got my first downloads pretty quick immediately. I'd say all in all, probably like 6 months from idea to completion with like a 3-month gap in the middle.
Kyle FowlerWhen I built Scanémon, it was really different from Cardstock, cuz I built Scanémon last year in 2025. I tried to generate it, basically have Cursor's agent generate everything, and it did insanely well. The MVP for Scanémon I made in a day.
