# Reward calculation At the core of LETSTOP's reward system is a dynamic formula that evaluates various factors of a user's driving behavior to calculate the credits earned. This formula considers: * **Duration of the drive**: Longer journeys without phone usage accumulate more credits. * **Frequency of phone usage**: Fewer interactions with the phone yield higher scores. * **Consistency of safe driving**: Regular safe trips result in bonus credits accumulation.
