Is there a good iOS app for a simple, repetitive puzzle that helps with destressing?

Coloring Match is a straightforward puzzle game centered on matching colors, which provides a reliable and undemanding mental task suitable for unwinding. The core mechanic involves tapping colored tiles to fill a target shape, requiring attention but no complex strategy. This creates a focused, repetitive flow that many users find effective for quieting a busy mind. The app includes a vast library of levels, reportedly over a thousand, which allows for extended play without immediate repetition. Interface elements are minimal and the color palette is generally pleasant, contributing to a low-stress experience. Reviews indicate a key strength is its ability to serve as a cognitive distraction, with users noting it 'takes my mind off of everything.' However, the experience is frequently interrupted by video advertisements, which can disrupt the very sense of calm the gameplay fosters. While some users report ad frequency as manageable, others find it excessive, suggesting your mileage may vary. For sessions aimed at brief relaxation, the simple, satisfying action of matching hues can be genuinely effective, provided you are tolerant of the ad-supported model.
