24 alternatives to Agent Arnold – Gym tracker 100% vibe-coded from my phone between sets
Agent Arnold is a gym tracker with a built-in AI coach. Here's how I use it: - "this exercise hurts my shoulder at the end of the movement, remind me proper form and cues" - "how should I modify my workout today based off last week's reps and weights" - `/generate` a bouldering-focused workout routine The app is free, your data is fully exportable (no walled-gardens), and there's an anonymous global leaderboard for motivation, including a "Dishonored" shameboard for anyone caught faking their numbers. I decided to 100% vibe-code this project, a part of it is halluci-coded. I purposely…

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.

ARVO▲8Hey HN, I've been lifting for years and got frustrated with fitness apps that either (a) generate a static plan and forget about you, or (b) require manual logging with no intelligence. So I built Arvo—an AI personal trainer that adapts after every single set, not just at the start of your workout. Why 19 agents instead of one? Each handles a specific job: - Exercise Architect (selects movements based on equipment/goals) - Load Navigator (calculates weight adjustments based on RIR) - Volume Manager (tracks MEV/MAV/MRV per muscle group) - Pattern Scout (extracts insights from…

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…
