Colorosaurus

No ads. No in-app purchases. No internet. Just 84 pictures to color, seven packs of them, and a brand new one whenever your child wants it.

No ads. Not one.

Colorosaurus is a color-by-number game for young children, built because the alternatives interrupt every thirty seconds.

WHAT'S INSIDE • 84 pictures across seven packs - dinosaurs, mandalas, stained glass, flowers, butterflies, fish, and storybook places • Three sizes, from a gentle 55 pieces up to 230 for a rainy afternoon • Surprise Me! invents a brand new picture on the spot, so it never runs out • Finished pictures are kept in a gallery to look back at

MADE FOR SMALL FINGERS • Forgiving taps - landing just outside the right piece still counts • Tapping the wrong piece never punishes. Nothing is filled in; the color that piece is waiting for simply gives a friendly bounce • A hint button zooms straight to the next piece • A magic wand finishes the current color, so being stuck never means fetching a grown-up • Pinch to zoom for the tiniest pieces • Progress saves by itself - put it down mid-picture and pick it up days later

QUIET BY DESIGN • No advertising of any kind • No in-app purchases • No internet connection required - it works in airplane mode • No accounts, no sign-in, no email address • Nothing is collected and nothing leaves the device

SOUND WORTH LISTENING TO Every piece plays a note from a pentatonic scale, so a picture colored in any order still comes out musical. Each color has its own pitch. Finishing one plays a little flourish. All of it can be switched off in two taps.

FOR PARENTS Turn on Guided Access (Settings › Accessibility) and the device stays in Colorosaurus until you enter your passcode. There is no browser, no store, and no way out of the app — so it is genuinely safe to hand over.

Works on iPhone and iPad.

Made by a dad, for his six-year-old.
