If by production you mean “done” and used by someone (i.e. by me) then I made https://skidmarks.club to replace my peloton subscription. You can browse and ride at https://app.skidmarks.club.

I’ve done ~10 rides with it so far. Hoping I can convince my wife to use it and save myself $50 a month. That would be my most successful side project by a wide margin.

There are probably a lot of examples like this. Vibe coded software people made for themselves, and other people could use it if they wanted.

All of the code was reviewed by myself, and I’m a programmer, so not sure if that fits the description. I didn’t go through it with a fine-toothed comb, however, and 90% of the review was on my phone. I also did some non-vibed setup for hosting, db, email, etcetera.

To me vibe coding is not looking at any of the code at all, but the definition reads a little loose to me these days, especially on HN, as: did an LLM “type” most of the code or did you? Either way I don’t think the term or definition is a big deal and probably not worth splitting hairs over.

Skid marks… not quite the skid marks I was thinking. Sorta fitting for a vibe coded app to be called skid mark though.

I thought it was a fun play on words

Curious about what you're using as a cycling platform -- just the Peloton, or are you on a bike trainer? There's a huge library of workouts out there (see [0] as just an example), but mostly targeted at % FTP. The flow path is generally create your workout in an app to generate the FIT file, then upload to the bike computer (or use Zwift). But they tend to not support cadence range as yours does. Would love to find something that gives me %FTP and cadence range!

I’m using the peloton only. I bought a little iPad/phone mount that I put on the handlebars. I run the app on my iPad, put the peloton in “just ride” mode (no subscription needed) and match the cadence/resistance with the web app.

When it comes to cycling I’m a complete novice which is why the workouts have resistance as % of total (what peloton does) and I recently added an option where you can switch to relevant effort in settings.

I appreciate this comment because I didn't know what people typically did for creating their own workouts and recently learned about FTP. I'm going to look into this!

There are several interesting projects around peloton hacking that have served as inspiration:

- [0] Peloton android app side loader: https://github.com/doudar/Openpelo

- [1] Overlays metrics on the Peloton: https://github.com/selalipop/grupetto

- [2] Bookmarklet to overlay cadence/resistance on web classes (this is what I started with): https://gist.github.com/rocng/2ff577948569ce0764b8938687841b...

- [3] Decodes Peloton metrics from the serial port: https://github.com/ihaque/pelomon

- [4] Transform Peloton into a smart trainer: https://github.com/doudar/SmartSpin2k/

These can be used in combination to use your Peloton with Zwift. Groupetto and Pelomon are really interesting. I'd like to integrate with something like Groupetto and use OpenPelo to have the full experience on the Peloton itself. That's kind of the end game, but I think the web app is the most approachable and easiest to get started with -- at least for me.

What do you mean you used your phone for code review?

I've lately seen a trend where people use their phone to instruct agent on the cloud to build applications. I presume this is beyond having RDP on your phone

I use Claude Code on the mobile app, it creates a PR, I click the link which takes me to the GitHub mobile app, I turn my phone landscape and scroll through the code. I give feedback in the Claude mobile app if needed and it pushes additional commits.

I try to keep my instructions pretty targeted so there aren’t too many LOC and files changed. That’s the goal at least.

I deploy on Vercel, so I get a preview build link I can click in the PR and try the site before I merge to main (trunk based). I use Supabase so if there is a DB migration I just run it in the Supabase console by copy pasting the SQL.

When I merge the PR it deploys to prod. This works pretty well for me.

What’s your setup to review (presumably) PRs on your phone?

[jacobrussell]

I just use the GitHub mobile app and turn my phone sideways

I was going to build this. Thanks for saving me the time!

Skidmarks club? Tell me you don't have a product person without telling me...

It's just a silly name :)
