## What is Core1?

Focus on one habit. Just one.

Core 1 helps you build one habit at a time. Plant a seed, watch it grow into a tree, and earn your reward when you're done.

Features:
- One habit at a time — no overwhelm
- Grow a tree as you build consistency
- Name your tree after who you want to become
- Set daily reminders
- Set a personal reward to celebrate your success
- Build a forest of completed habits

Start small. Stay steady. Watch it grow.
