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…
What it does
In the maker’s words, at launch
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.

all alternatives →- VCVibe coded iOS workout app with Apple Watch supportFeb 2026 · apps.apple.com · ▲8
I spent a month to put together a workout app without writing a single line of code by hand. It's on par with many apps like Fitbod or Fitness AI. Got approved on iOS App Store. Let me know if you want free access, only thing I ask is to give me genuine feedback and one feature you would like to see. I will be asking Codex/Claude to rank the top features and implement it.

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…
- VCVibe coding creates a mess, but it can be solved faster2025 · ▲5
I've been using Cursor, Co-Pilot, ChatGPT, Claude and what not since quite some time now, and we are at a stage where we can just "vibe code" whole apps from idea to execution in a few prompts. I tried this personally to create some side projects that solved little problems for me. But I always got stuck at a point where it just goes into an infinite loop of issues and can't solve the issue by itself. Well I'm a developer, so it's easier for me to dive into the code and solve the problem myself, but that would take a hell lot of time to understand all the code AI wrote for me. If I keep…

As an experiment I let Claude Code write 100% of the code to begin a project management application. Total spent: $30 Time: 2hours I did this so showcase what Claude produces and to also get feedback on how well you think it did.

We built this on a whim for a hackathon, but I'm thinking to turn it into a real thing! Original GitHub repository at: https://github.com/Flux159/claude-code-go The desktop app exposes an interface to Claude Code, so you can run Claude Code from your phone.
