I deleted all my other colouring apps. This is my favourite. The relax mode with the music annoyingly has ads. Obv. because the volume is on it means the adverts shout at you! Not relaxing! And I wish we were able to click one link on their Facebook page and download all the bonus pics instead of painstakingly going through every post and every link for each pic. But overall, it's a good way to chill out and has beautiful pics, colours and detail.
