Margo – Find the font your brain reads fastest
Single-page font test with no depth beyond basic timing measurements.

The product is gloriously simple: a big, tappable timer with scroll-to-adjust, keyboard start, and periodic 'confirm your presence' prompts, plus import/export so your data never has to leave the browser. That local-first approach and the razor-minimal UI make it frictionless to try, but it stops short of being sticky — no session history, analytics, or nudges to turn short experiments into habit. Great as a focused tool for a specific practice, not yet a long-term habit platform.
