There's no shortage of drawing programmes on the internet or among app marketplaces. One simple, child-friendly version is the free How to Draw for iOS and Android. Beginner doodlers get step-by-step advice on how to draw a bright Christmas tree or a friendly turtle. There are 60 designs included, with a variety of difficulty levels.
The app is financed by advertisements.
For those who would prefer to do without ads, there's a Pro version that only costs a few euros (1 euro equals 1.12 dollars) a month.
