I replaced my premium workout app with vibecode

I was going through my app subscriptions and realized I was paying $15 for a pretty good workout app, which seemed a bit high to me.As a software engineer who is also well versed in claude code, I realized that I could likely vibecode a very similar app, or even build something more to my liking. I challenged my self to build something roughly equivalent this afternoon.Workflow was: start with a detailed spec from Claude code describing many of the features common in workout apps. Then paste this into lovable to have it build out the initial mvp.Once that was built, I used claude code extensively to modify the app until it was usable, including adding an import from the costly premium app.While there are bugs, I think I might use this app. And it is insane that we are in a place where I can build this on my phone during an afternoon. In a few years, the economics of apps is going to be different, at least for folks willing to work a little bit.In theory this project will save me over $190 a year.
