Routina-AI Habit Tracker

Routina is a smart habit management app that tracks your daily habits and uses AI to analyze your patterns. No more broken resolutions — with Routina, anyone can become consistent! This update brings group challenges with friends and a new weekly letter from your AI coach 'Maru'.

1. Simple Habit Check-ins
Create your own habits — drink water, exercise, read, meditate, take vitamins, journal, and more. One tap is all it takes! No complicated forms or lengthy entries — just a quick check to complete today's habit.

2. Streaks & Your Garden
Every day you check in, your streak grows and the on-screen plant evolves: seed → sprout → sapling → growing → bloom. 3 days, 7 days, 30 days, 100 days — the numbers fuel the motivation. Miss a day and it resets to zero. That tension is the secret to consistency.

3. Achievement Celebrations
Complete all your daily habits and confetti fills your screen. Even small wins deserve celebration.

4. Calendar Heatmap
View your monthly progress at a glance. Darker colors mean more habits completed. Fill every square like a GitHub contribution graph — oddly satisfying.

5. Weekly Letter from AI Coach 'Maru' ✨ NEW
Every Monday, Maru analyzes your past week and leaves you a warm, personalized letter — automatically. Honest completion rate, your strongest ritual, what wobbled, and a small nudge for next week. A different message every week, never the same boilerplate. Letters stack up in the Maru tab so you can look back at your growth.

6. Small Circles & Group Challenges ✨ NEW
One friend code is all it takes. Form a small circle, take on the same 21-day challenge together, and see who's checked in today at a glance. Doing it together is way easier than doing it alone. You can also browse public challenge rooms anyone can join.

7. Korean / English ✨ NEW
The whole app now speaks both Korean and English naturally. Use it abroad with no friction.
