What's a good Android app for stress relief through casual drawing?

Color Pop is a well-regarded coloring and drawing application that serves as a digital art studio for casual users seeking relaxation. Its primary draw is a vast and frequently updated collection of coloring book-style templates, ranging from mandalas and animals to pop culture-inspired designs. Users simply select a color from the palette and tap to fill sections, creating polished artwork with minimal effort—a process many find meditative. Beyond solo coloring, the app incorporates a social layer where artists can publish their completed pieces to a shared feed, receive 'hearts' (likes), and comment on others' work. This community aspect adds a light, encouraging dimension to the experience. However, some reviews point to occasional inconsistencies in how the app's algorithm surfaces popular creations, with users sometimes questioning why works with fewer likes appear more prominently. The interface is intuitive and the act of coloring is genuinely soothing, making it a strong recommendation for winding down after work or during short breaks. While advanced artists might find the tools limited, for its intended purpose of accessible, stress-relieving creativity, Color Pop delivers effectively.
