I just finished 75 Hard and one thing that surprised me was how hard it was to find a really minimal way to track progress. Most of what I found was either overly complicated or bundled into big habit apps. So I built something simple for myself and put it up at 75hardcalculator.com.

You enter your start date and it shows: • What day you’re on • How many days are left • Your exact finish date • A simple 75-day visual so you can see the days stacking up

No account needed. Just a clean way to see where you are and how close you are to Day 75. If you’re in the middle of it (or about to start) and want something minimal, it might help.
