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…

Vibe coded iOS workout app with Apple Watch supportFeb 2026 · apps.apple.com · ▲8I spent a month to put together a workout app without writing a single line of code by hand.

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.
ARVONov 2025 · arvo.guru · ▲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…

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
