Pletto is a colouring book and drawing pad made for the youngest hands.

Tap any part of a picture and it fills with colour. Drag a finger across the page and it keeps filling. There is nothing to read, no menus to get lost in, and nothing that can go wrong.

105 PICTURES
Animals, vehicles, food, dinosaurs and sea creatures, plus scenes to get lost in: a farm, a pirate ship, a treehouse, a fire station, the arctic. Big simple shapes for the youngest, busier pictures for when they are ready.

FREE DRAW
A blank sheet whenever they want one. Three crayon thicknesses and a spray can.

DRAW ON YOUR PHOTOS
Snap the dog, the cake or grandma, or pick a photo you already have, and it becomes a page to scribble on. The camera sits behind a press-and-hold meant for a grown-up, and photos stay on your device.

TURN A PHOTO INTO A COLOURING PAGE
One tap on the magic wand finds what the photo is of and draws it as a proper colouring page: the dog, in bold lines with big areas to fill, and nothing behind it to get in the way. The drawing is done by the app on the device itself - the photo is never uploaded.

STICKERS OF YOUR OWN THINGS
The wand also cuts the dog out of the photo as a sticker - or the teddy out of the picture they just coloured, or a drawing off its sheet. Every sticker they make waits in the sticker tray to press onto any other picture, so their own dog can go and live on the farm. Sixteen stickers come with the app too: stars, hearts, a rainbow, a dinosaur, a unicorn, a rocket and more.

CRAFTS TO PRINT, CUT OUT AND BUILD
Thirteen of them: a crown, finger puppets, a cat mask, a picture cube, a party hat and bunting - and games to make and play: a race board game with its own spinner and counters, a dot dice, suns-and-moons noughts and crosses, pairs cards, a magnet fishing game, spinning tops and a pinwheel. Colour them in, and a grown-up prints them, with the steps and the rules on the sheet. Dashed lines to cut, dotted lines to fold, a glue tab where one is needed.

WATCH IT DRAW ITSELF
A play button replays any drawing stroke by stroke, the way it was made.

MIRROR AND KALEIDOSCOPE
Switch on the mirror and every line is drawn twice; switch on the kaleidoscope and one scribble becomes a twelve-way pattern.

PATTERNS, RAINBOW AND GLITTER
Fill with stripes, dots, checks, stars, zigzags, rainbow or twinkling glitter, in any of sixteen colours - or draw with a rainbow crayon and a glitter crayon. The same tools work on a picture or on a blank page.

IT SAYS THE COLOURS
Pick a colour or a sticker and Pletto says its name in your phone's language: English, Spanish, French, German, Portuguese or Danish.

EVERY PICTURE IS KEPT
There is no save button. Work is written to the device as it happens, so nothing is lost by closing the app. Finished pictures and drawings collect under My Pictures, and tapping one opens it again to carry on. The same picture can be coloured over and over, and every attempt is kept. A grown-up can press and hold to put a favourite into the phone's photos, to keep or send to grandma - or to print it, and a blank page prints as a colouring sheet.

MADE TO BE HANDED OVER
• No ads, ever
• No in-app purchases
• No accounts and no sign-in
• No analytics and no tracking
• No internet connection used at all
• Photos never leave the device
• The camera is the only permission, and it is only asked for when a grown-up opens it (on Android 9 and older, saving to the phone's photos also asks for storage access)
• The back button steps out of a picture, never out of the app

Clearing a page needs a deliberate press-and-hold, and undo will put back even a full wipe — so an accidental tap cannot destroy an afternoon's work.

Pletto works in portrait or landscape, on a phone or a tablet, and works just as well on a plane as at home, because it never needs to be online. (Printing goes through Android's own print service, which talks to the printer; the app itself still has no internet access.)
