Very affordable coloring app

[Racineur]

Hi, do you know of a very affordable coloring app. I feel like I need a coloring book. I found many but they all ask a fortune for a monthly and even weekly subscription. Not that I don't want to pay, I'd buy an app. But I'm no artist and I want to try the possibilities of my new iPad Air 4. I got the pencil. Now needs the app. Does Apple have a dedicated app?
Thanks as always.

There is e.g the free Sketchbook - which should cover most needs for drawing or coloring any picture. You load the image you want to color and off you go. ?
A dedicated coloring book app offers the convenience of a permanent flow of motives - which is probably what you pay for.

EDIT: if you like to start working on vector based art, the free Vectornator comes highly recommended.
