About

GrowIsland

Features
Read full description

Grow Island is a family coaching app that helps kids build study routines, daily habits, and simple mood reflection with their parents. Each completed mission gives XP to a growing island. Parents can create missions and rewards, while kids can complete tasks, request approval, and propose new goals or rewards of their own. It turns everyday routines into a shared family rhythm built around encouragement instead of nagging. Key features - Mission management: create goals for study, reading, homework, exercise, tidying up, sleep, self-care, family promises, and more. - Repeat schedules: set one-time, daily, weekday, weekend, or custom weekly missions. - Parent approval: review a kid's completion request, approve it with praise, or send it back with a gentle note. - Grow Islands: learning, health, creativity, social, responsibility, and challenge islands grow with XP. - Reward shop: create real-life rewards such as game time, snacks, or family activities. - Kid proposals: kids can suggest missions and rewards for parents to review. - Mood check-in: kids can log today's feeling and a short note. - Family linking: connect parent and kid accounts with an invite code. - Notifications: stay updated on missions, approvals, and reward requests. - Optional Parent Plus subscription: remove ads for the family and expand limits from 1 parent or guardian / 1 kid to 3 parents or guardians / 3 kids. Grow Island is designed as a small, positive growth space where kids can try, reflect, and feel supported by their family. Mood check-ins are for family conversation and self-expression. They are not a substitute for professional counseling or medical care.
