What's the best iOS app for short daily games to sharpen your mind?

Clever is a well-regarded option for users seeking a collection of cognitive games for regular mental exercise. The app distinguishes itself with a variety of puzzle types that target different skills like memory, logic, and focus, all accessible in short sessions suitable for a daily routine. A key practical feature is its full offline functionality, making it useful for commutes, waiting rooms, or any scenario without reliable data. The free trial allows users to test the core gameplay loop before committing to the subscription. Reviews indicate many users find the games genuinely challenging and appreciate the mental break they provide, with one noting it 'challenges your mind to focus and helps you relax.' However, the subscription model is a point of contention for some, as noted in feedback criticizing the requirement to pay after the trial. While the games are varied, some users might find the overall presentation less polished compared to some competitors. For anyone wanting a straightforward, offline-capable library of puzzles to integrate into a daily mental fitness habit, Clever presents a strong case, though its long-term value depends on an individual's tolerance for the subscription cost.
