NibbyBot
Read full descriptionHide full description
Your child's first coding adventure ends with something magical: a drawing they made themselves, that comes alive. NibbyBot is a coding-and-drawing adventure for kids ages 5-8. Instead of typing code, children arrange playful picture blocks. Nibby the robot then follows their program step by step — moving, turning, switching colors, and stamping shapes — until a real drawing appears on the canvas. Then the drawing springs to life as an animation, ready to decorate, save, and show off. WHY KIDS LOVE IT • Code by playing — snap together colorful blocks, no reading or typing required • Watch Nibby draw — the robot executes every command they placed, line by line • Art that moves — finished drawings animate with wiggles, spins, and floats • Make it theirs — decorate with stickers, brushes, stamps, and backgrounds • Collect rewards — unlock bot skins, stickers, and badges through play, never through chores WHY PARENTS TRUST IT • 100% kid-safe: no ads, no accounts, no chat, no open social features • Works fully offline — a real toy, not a streaming service • No dark patterns: no streaks, no energy bars, no leaderboards, no pressure • A protected Parent Zone handles all purchases and settings • Artwork stays on your device and is saved to Photos only when a grown-up asks HOW IT WORKS 1. Pick an adventure — 52 levels across 4 themed worlds: Color Path, Magic Brush, Loop Forest, and Animation Factory 2. Arrange the blocks — sequence, loops, colors, and stamps teach real coding logic 3. Press play — Nibby draws the program, the picture animates, and the decorating begins BEYOND THE LEVELS • Free Coding: an open canvas where kids invent their own programs and drawings • Free Draw: a full drawing studio with pencils, stickers, and backgrounds • Decoration Studio: revisit any finished artwork and keep creating The first 8 adventures are free. Unlock everything with a monthly or yearly subscription, or own it forever with a one-time purchase. Family Sharing supported. Designed for iPad and iPhone. Built for the way 5-8 year olds actually think: one idea per screen, gentle guidance, and a "try again" instead of a "you failed." Download NibbyBot and watch your child code their very first drawing today. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
