My oldest (12) likes to draw, and is currently using a free version of ibisPaint on her phone.

What's a good upgrade to that?

I'd love to get her a tablet + pencil, but I'm not quite ready to shove an overpriced Apple thing in her hands. But I also want to encourage her and not give her crappy tools/software.

@pixelambacht krita on android? I've never used it, and have only used the desktop version a small amount. But it's used for real work and 12 is, in my opinion, old enough to start dabbling with real tools.
@drj Real tools definitely. ibisPaint looks like a pretty extensive tool though, so this might be adequate enough. Krita looks nice too though, I'll show it to her.
@pixelambacht @drj My boy (11) has been using Krita on the desktop for his cartoons and drawing. I've given him a wee Wacom tablet to play with as well but he prefers to use the mouse. Krita is large and complicated but he can easily draw with it and then pick up little bits from Youtube tutorials.
@simoncozens @drj Parallel to this adventure she needs to get a laptop for school, so I'll put Krita on that. More tools to discover!
