What's the best Android app for short, daily brain training exercises to improve focus?

Neuro is an application built for users seeking to sharpen their cognitive functions through regular, manageable practice. It stands out for this specific use case by providing a library of quick games and challenges that target areas like attention, memory, and processing speed. These exercises are designed to be completed in just a few minutes, making them easy to integrate into a daily morning routine or a short afternoon break. A key feature is the personalized training plan, which adapts suggested activities based on initial assessments and ongoing performance metrics. For someone working a desk job who struggles with afternoon distractions, using Neuro for a 5-minute session could serve as a focused reset. The app includes progress tracking with simple graphs, allowing users to observe subtle improvements in their reaction times or puzzle-solving consistency over weeks. However, reviews indicate some users find the free version too limited, locking more advanced exercises behind a subscription. The interface is clean, though a few users note that the transition between different game types can feel slightly sluggish on older devices. As a tool for building a consistent mental exercise habit, Neuro provides a structured and data-informed approach, even if its long-term impact on real-world focus varies by individual.
