Urban Green is an application designed to promote urban greening and sustainable living through plant sharing. Users can share plants with the community and identify them through markers on the map. With Google's Gemini AI, users can easily understand plant care needs, including watering, fertilizing, and pruning. Additionally, the AI provides proactive notifications based on environmental factors such as location, weather conditions, and seasons to predict the plant care requirements. Users can earn achievements by caring for plants, enhancing the fun and engagement of the experience.
