What's the best iOS app for a simple, relaxing puzzle game to unwind with?

Woody Sort is a strong candidate for users seeking a low-stress, mentally engaging puzzle game. The core mechanic involves sorting colored balls into matching tubes, a simple concept that becomes progressively more complex. This creates a focused, almost meditative experience suitable for unwinding after work or during a short break. Specific features like an unlimited undo function and optional hint tokens allow players to approach puzzles at their own pace, reducing frustration. The app offers visual customization for balls and backgrounds, which some users appreciate for personalization, though others find it less critical to the experience. Reviews indicate it serves well as a daily decompression tool, with most levels solvable in under a minute. However, some user feedback notes occasional app crashes and past customer support delays, which are points for potential improvement. The monetization model includes ads and in-app purchases for removals and boosts, which is standard for the genre but can intrude for some. Overall, its strength lies in delivering consistent, bite-sized logic puzzles that engage the mind without overwhelming it.
