Octopus has launched four adult colouring-in and dot-to-dot apps which can be completed on screen using a finger.
The Colouring for Mindfulness series, the first digital range of colouring-in titles, has been created in collaboration with developers Papertrell. The apps can be downloaded free from the App Store (iOS-only), and each offers one drawing for free and others available as in-app purchases (£1.49 for each collection, or multiple buys discounted).
"World Mandalas" is made up of 100 traditional and contemporary mandala circle designs sourced by author Madonna Gauding from spiritual traditions around the world, and includes sections on Hindu, Buddhist, Christian and Celtic mandalas; while "Flower Mandalas" comes from artist and illustrator Cynthia Emerlye.
"Dot-To-Dot", from graphic designer Thomas Pavitte consists of dot-to-dot puzzles of 1,000 dots apiece, with completion time estimated at one hour. The subjects are animals, cityscapes, masterpieces and iconic portraits. Octopus said: "His unique style, when combined with iconic subjects, results in images that are not only absorbingly fun to join, but cool enough to save, share, and print for your wall."
Pavitte is also the creator of Querkles, a collection of colour-by-number puzzles which resolve from "abaffling tangle of circles" to reveal a hidden image – again, either "masterpieces" or "iconic portraits" - within.
Group publishing director Denise Bates said: "We love the idea of taking these beautiful and creative illustrations into the digital space, and making the first range of colouring-in apps available."
