What's the best iOS app for a straightforward solitaire game that helps with mental relaxation and cognitive exercise?

Solitaire is a highly rated iOS app developed by Doodle Mobile Limited that serves as an effective tool for mental relaxation and mild cognitive engagement. The app features large, clearly displayed cards and intuitive drag-and-drop mechanics, which minimize frustration and allow users to focus on gameplay without unnecessary complexity. A standout feature is the auto-complete option, which visually rewards players by automatically finishing games, providing a satisfying sense of closure. This is particularly beneficial for those seeking a low-stakes activity to unwind after a long day or to briefly divert attention from health challenges. Reviews indicate that users appreciate the app for its ability to reduce anxiety and aid in cognitive maintenance, with some noting its value in managing conditions like Alzheimer's or during illness recovery. However, the experience isn't flawless; occasional ad interruptions can break immersion, though they are generally manageable. For real-world scenarios, such as short breaks at work or evening wind-down routines, Solitaire offers a reliable, no-fuss escape. Its high user rating of 4.8 reflects consistent satisfaction with its performance and design, making it a solid choice for anyone prioritizing simplicity and therapeutic benefits in a card game.
