Building a Habit Tracker with Next.js

I've always struggled with consistency. Whether it's coding, exercising, or reading — I start strong but fizzle out after a week. So I built a habit tracker to solve this problem.

Why Build Your Own?

There are plenty of habit tracking apps out there. But I wanted something that:

• Was simple and distraction-free
• Focused on streaks, not stats
• Looked good enough that I'd actually want to open it daily

The Stack

• Next.js — For the framework
• TypeScript — Type safety for habit data structures
• Tailwind CSS — Quick, consistent styling

Key Features

Streak Tracking

The core feature. See how many consecutive days you've completed a habit. Miss a day? The streak resets. Simple but effective motivation.

Daily Dashboard

One page that shows all your habits for today. Check them off as you go. No clutter, no noise.

Weekly Overview

See your week at a glance. Green dots for completed days, grey for missed. Visual patterns emerge quickly.

Lessons Learned

1. Keep it simple — I almost added categories, reminders, analytics. Glad I didn't. The app works because it's minimal.
2. Mobile-first — You check habits on your phone, not your desktop. Design accordingly.
3. Streaks are powerful — The psychological weight of a 30-day streak is real. Don't break the chain.

What's Next

Maybe add a simple API so other apps can read habit data. Or a widget for quick check-ins. But honestly, the core is done and it works.

The best productivity app is the one you actually use.
