Charles — Periodised Strength Training

What it does

I build your training programme. Periodised strength training, tailored to your body, your equipment, and your goals.

I am Charles, your AI gym coach. I build your personalized gym training plan and adjust it after every session. Free for 14 days on the yearly plan. iOS and Android.

A real training plan, adjusted after every session around how you train and what life throws at you. I handle the programming, you just train and get stronger. Built by personal trainers and coaches, for the people they could not train themselves. Most people walk into the gym and do the same machines every week. No plan, no progression, no results. Other apps don't fix that. They log what you did, or guess your next set. None of them own the plan. I do. I write your whole programme, read every session you log, and adjust what comes next after each one. Travelling, a packed week, coming back from pain, the plan follows your life. You keep getting stronger without ever thinking about what to…from getcharles.pro

  I trained a 125M model to autocomplete piano on-device▲598

  I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
