Paritose uses camera input to detect when users look away or use their phone, then triggers a loud alarm until the user refocuses. Unlike other productivity apps that use point deductions or other such features, Paritose provides a real-time consequence that is actually unpleasant. The unpleasant experience motivates and forces users to stay focused. Paritose also has other productivity features such as a pomodoro timer and a to-do list for user convenience.
