Merro is a macOS habit reminder that doesn't pretend your life is a productivity system. No streaks that guilt-trip you. No dashboards designed for investors. Just a small app that sits in your menu bar, nudges you at the right time, and says things like "It's still sitting there. So what's the plan?" Set your habits. Pick how annoying the reminders should be. Earn rewards for showing up. That's it. Free. Local-only. No account. No data leaves your Mac.
