Habit Tracker is a free daily habit tracking tool with a weekly heatmap view and streak counter, designed to support habit formation for ADHD brains. Building consistent habits is particularly challenging with ADHD because the brain's reward system — which normally reinforces repeated behaviors — functions differently. This tool provides the external structure and immediate visual feedback that can help bridge that gap. The weekly grid shows Monday through Sunday with each habit as a row. Click any cell to log completion for that day. Checked cells show a green checkmark, providing a satisfying visual reward. The streak counter shows how many consecutive days you've completed each habit, gamifying the process and creating motivation to maintain your streak. The summary section shows total habits and completion ratio for today, giving you an at-a-glance progress overview. Add habits with custom names and emoji icons to make the tracker personal and engaging. Example habits include Drink Water, Meditate, Exercise, Read, Take Medication, and Sleep by Midnight. The tool uses localStorage for persistence, so your data survives browser sessions. This free ADHD habit tracker is useful for building morning routines, medication adherence, exercise consistency, hydration tracking, reading goals, and any daily habit you want to establish. Unlike complex habit apps with notifications and analytics, this tracker is deliberately simple — just add, check, and watch your streaks grow. The minimalist design reduces cognitive load while providing the essential feedback loop that habit formation requires.
