About

Doodle Turtle

Read full description

Doodle Turtle draws at the speed of a three-year-old. Every other drawing app moves at a grown-up's pace. A line appears, then another, then another, and your child is still working on the first one. So you end up hovering over the pause button, rewinding, pausing again. Ask any parent of a preschooler how that goes. Doodle Turtle fixes it in the simplest possible way. It draws one line, slowly. Then it stops. And it waits, with a real and generous pause, long enough for a small hand to finish before the next line begins. No pause button required. Nobody is rushing anybody. That is the whole app. HOW IT WORKS 1. Your child picks a picture: a cat, a fish, a house, an ice cream. 2. Doodle Turtle draws it once, all the way through, so your child can see where it is going. 3. Then it starts again, one stroke at a time, with a warm voice saying what to draw ("A big round face!"), a gentle ding, and a quiet pause while your child draws that stroke on their own paper. 4. At the end, their drawing goes into a picture frame. Because it should. WHAT IS INSIDE - Slow, stroke-by-stroke drawing lessons made for ages 3 to 5 - A spoken cue for every single stroke, clear and encouraging - Two speeds: Turtle for the youngest hands, Bunny once they are confident - Tap mode, where your child taps when they are ready, so the app never moves first - Draw on the screen: trace over a faded guide with a fingertip - Free Doodle: a blank canvas for when they just want to invent something - Coloring: tap a space to fill it or a line to color it, or use a crayon that stays inside the lines - Printable tracing sheets for every picture, for crayons and real paper - Works completely offline, in the car, on a plane, in a waiting room BUILT FOR SMALL PEOPLE - No ads. Not one, anywhere, ever. - No in-app purchases, no subscriptions, no upsells. - No accounts and no sign-in. Nothing to type. - No data collected. No analytics, no tracking, no server. The app makes no network requests at all. - The one link that leaves the app sits behind a parental gate a young child cannot pass. - Big buttons, no menus to get lost in, nothing breakable. WHY A TURTLE I built this for my daughter, who is three and a half, who loves to draw, and who was getting frustrated with every drawing video we tried because all of them went too fast. She picked the turtle. He is slow, and that is entirely the point. Doodle Turtle is quiet, patient, and never in a hurry. Neither is your kid.
