About Little Crayons - Kids Colouring App for Android
Ready-to-publish kids' colouring app: 436 pictures, in-app purchases, source
Little Crayons is a complete, polished colouring app for children aged 3-6, ready for you to rebrand and publish on Google Play. It has never been published, so you launch it fresh under your own developer account. Children pick a colour and tap a shape to fill it - no reading needed. There are 436 original pictures in 20 books: Farm, Zoo, Under the Sea, Dinosaurs, Garden & Bugs, Unicorns & Fairy Tales, Princesses & Mermaids, Space, Vehicles, Robots & Toys, Yummy Food, ABC, plus Spring, Easter, Summer, Autumn, Halloween, Winter and Christmas. The seasonal books move to the front automatically. FEATURES Tap-to-fill colouring with 18 colours, undo and start again Magic brushes (glitter, rainbow, dots, stars, stripes), 36 stickers and free crayon drawing Confetti and happy sounds when a picture is finished "My art" gallery - every picture saves automatically Print (coloured or a blank page to colour with real crayons), save to gallery, share Grown-up check before purchases, sharing, printing and settings (Google Play Families policy) Phone and tablet layouts, works fully offline, 2.6 MB MONETISATION BUILT IN 4 one-off in-app products: Everything (£4.99), All pictures (£2.99), Magic brushes (£1.49), Sticker pack (£0.99) Google Play Billing Library 8 code already written (purchase, acknowledge, restore, local prices).

Reason for selling
I build and sell finished apps rather than running them long-term. This one is complete and ready to publish, and it will do best with an owner who can launch it under their own Google Play account and put time into marketing it.
