Kyle Fowler - How I make $42k/mo passively with simple no-code apps (copy me)
Kyle FowlerSo, the origin story is that I was-- in back in 2020 or back in 2019, even, I wanted to sort and catalog my baseball cards. And as I was doing it, I was like, "Oh, well, like I'd love to digitize them while I sort them." And so, I went on the App Store to look for an app and no app existed, and I was getting into app development at the time. This is like way pre-AI or anything.
Kyle FowlerSo, I'd done a course on it, and so I was like, "Oh, I guess I'll build it." And then, I started building it and knew nothing, but like kind of got into it. And then, I eventually like stopped working on it for a while until some dude on Reddit DMed me and was like, "Hey, you still working on this?" 'Cause I made like a Reddit post to validate my idea before building because I'd seen on Twitter some- something that I was supposed to do that. So, I like had a Reddit post and 10 people replied, and I was super excited about it. But anyway, this dude reached out. I have the--
Kyle FowlerI don't know if it makes sense. I was I have the screenshot of this dude DMing me [laughter] on Reddit.
Joseph ChoiSo, you made a Reddit post. Did the Did that initial post get a lot of reception for the idea?
Kyle FowlerIt didn't get like crazy reception, but like I made it in r/baseballcards, which wasn't like a huge subreddit. But I got I don't know, I mean like f- like 12 people replied or something or like 15 maybe, and they were like, "Oh, I I'd love to use this." And so, that gave me a decent amount of validation.
Kyle FowlerIt's funny thinking about it now 'cause now we make TikToks that go to, you know, thousands and thousands of people and with tons and tons of comments, way more engagement. But like that Reddit post was like huge for us.
