Hey Product Hunt! I'm Marcel, the maker of Markd Timeline. I've been using Whoop for several years, and it made me want to track more of my own inputs and understand their effects on me better. I've always been a bit obsessed with optimization, usually in the digital world with things like split keyboards, macros, and scripts. Eventually I wanted to apply that same mindset to daily life too. The problem was that I didn't just want to log things. I wanted to understand cause and effect. Was that coffee 2 hours ago or 5? Did I last eat at 9 or 10? Why is my energy lower right now? I needed something that showed exactly when things happened and how long ago they were, but I also needed logging to be fast enough not to annoy me. I really hate slow software. That led to Markd: a timeline-first, low-friction tracker where you can log in seconds, keep everything local-first, and optionally share your timeline with AI for deeper analysis. Thanks for checking it out. I'd love to hear what you'd want to track with it, or what you feel existing trackers still get wrong.
