BetterHabitsDaily

BetterHabitsDaily is a free habit tracker for developers, not for the wellness-app crowd. Everything lives in your browser's localStorage. No signup, no account, and the data never leaves your machine — you open the page and you're already using it.

Presets include "Deep work 2h," "No social media until noon," "Stand up and stretch," and "Lights-out by 11," plus anything else you want to add. Tick them off daily and you get a streak count. That number does more work than it should; people who ignore every other stat still won't break a 40-day streak.

Completed habits earn XP and level you up, and there are 20 daily challenges rotating through focus, health, fitness, and discipline. It's all free — no paid tier, nothing held back. There's a weekly blog too, mostly about deep work, burnout, and how developers structure their days.
