Focus apps: do they really boost productivity?

Focus apps, like Focus Friend, use gamification and psychological principles to encourage productivity. These apps employ incentives, reward substitution, and commitment strategies to help users stay on task. However, research on their effectiveness is limited, with some studies suggesting simpler methods are more successful. While focus apps can aid in resisting phone checks, they don't address underlying distractibility. True focus improvement may require self-awareness and conscious response to distractions rather than solely relying on apps.
