OWL Sessions
Thirty, forty-five or sixty minutes of exercise from a library of seventeen moves, each under a timer and a rep count, with a minute of rest between blocks.
Small tools that run in your browser, with nothing uploaded
Each app here keeps the same promise: a browser tab, your own files or your own body, and nothing sent anywhere. No account, no upload. Each lives in its own public repository, and you can install it on your phone from its page.
The OWL apps serve the framework of the same name, Optimal Wealth and Longevity: mind, muscle and money as three kinds of capital that compound when tended and decay when left alone.
