# Stell (StellKey) > Stell is a gamified habit-building app that helps parents of children aged 3-14 build healthy daily routines — morning routines, chores, toothbrushing, screen-time balance, sleep — through a joyful 3-minute daily ritual backed by neuroscience. Stell turns habit-building into a game children love. Parents set up adaptive daily missions in minutes; children complete them on a vibrant mission board, earn stars and diamonds, and progress through an 8-world journey. The approach is grounded in 2024-2025 developmental psychology and habit-formation research: single-action missions, immediate positive reinforcement, streaks, and parent validation instead of punishment. ## Key facts - Product: Stell (also written StellKey), a Progressive Web App for phones, tablets and shared family devices — no app-store install required. - Audience: parents (primarily mothers) of children aged 3-14, including children with ADHD or ASD profiles. - Core loop: a 3-minute daily ritual — the child completes 4 auto-generated daily missions, the parent validates them in one tap, and the child is celebrated in real time. - Dual interface: a warm, professional parent dashboard (progress tracking, streak analytics, AI parenting coach) and a playful child interface (mission board, avatar customization, shop, trophy room). - Age-adaptive: UI, PIN complexity, text-to-speech voice and visual effects adapt to the child's age (3-5, 6-9, 10+). - Languages: 11 languages including English, French, German, Spanish, Italian, Portuguese, Polish, Dutch, Japanese, Arabic (RTL) and Simplified Chinese. - Pricing: free tier (up to 3 children, daily missions) and Premium with a 7-day free trial (AI parenting coach, coaching programs, unlimited features). - Privacy: family data is private per account, GDPR-compliant, with guest mode that works before account creation. ## What Stell helps parents with - Morning routine checklists for kids: wake-up, getting dressed, breakfast, toothbrushing — without the daily battles. - Chore charts for kids: age-appropriate chores turned into rewarding missions instead of negotiations. - Toothbrushing and flossing: a guided 2-minute brushing timer with quadrant-by-quadrant animation and music, plus a floss timer. - Screen-time balance, bedtime routines, reading habits, emotional regulation and sibling cooperation. - Special-needs support: adapted strategies and extra-patience tips for children with ADHD or ASD. - AI parenting coach ("Ask Stell"): warm, science-backed answers to everyday parenting questions, with the ability to generate personalized daily missions from a parent's goal. ## Frequently asked questions ### How do I get my child to follow a morning routine without nagging? Stell turns each morning step (get dressed, eat breakfast, brush teeth) into a short mission the child checks off for stars. Parents validate in one tap and the child is celebrated instantly, which replaces nagging with positive reinforcement.

Stell is a chore chart app designed for children aged 3-14: parents assign age-appropriate chores as missions, children earn stars and diamonds they spend in a virtual shop, and streaks keep motivation high.

Stell's toothbrushing mission includes a 2-minute guided timer that shows which quadrant of the mouth to brush, with music that speeds up as the timer progresses and a celebration at the end. ### Is Stell suitable for children with ADHD or ASD? Yes. Onboarding includes ADHD/ASD profiles, missions are single-action and short, and the AI coach provides adapted strategies and patience tips for parents. ### How much does Stell cost?
