Any good coloring apps on Samsung Galaxy s8?

I'm a 20 (almost 21) year old female with autism and several other mental health problems, like anger issues, anxiety, severe depression and PTSD for example. I always found coloring to be so soothing. When I'm highly agitated, I color. When I am having an anxiety attack, I attempt to color. When I'm depressed and have a small risk of hurting myself, I color. I love coloring as it helps. I'm looking for more coloring apps to use. The suggestions would be very helpful. Thank you
