## What is 2B?

2B-Alert is an AI-based smartphone app that provides three capabilities to help optimize your mental acuity. You can measure your current alertness level by performing a psychomotor vigilance test (a reaction-time test), predict your future alertness levels, given your sleep and caffeine-intake schedules, and obtain customized recommendations for countermeasures (i.e., caffeine intake) that optimize your mental acuity at future desired times.

2B-Alert enables users to assess their current alertness level and predict future alertness levels during a mission to anticipate and overcome periods of high alertness impairment. To plan accordingly, the app allows users to evaluate the effectiveness of different caffeine consumption schedules and tactical naps to mitigate alertness impairment. In addition, the app provides caffeine consumption recommendations that optimize the user’s mental acuity at future desired times (critical mission periods).
