SPOBY is a free iPhone app developed by CUVEYES INC. that falls under the Lifestyle category with a focus on Health & Fitness. The app encourages users to reduce carbon emissions by walking or cycling instead of driving. It measures the suppressed CO2 emissions from the vehicle that would have been used for the same distance and converts it into decarbonization points. Users can collect points and exchange them for rewards within the app.

The app records daily steps and distance traveled through CMPedometer and HealthKit. It also scores the suppressed CO2 emissions and provides details on the number of calories burned and total workout time. The app provides a visualization function that allows users to see their weekly, monthly, and yearly activity. SPOBY can also be used to host online marathons through its cloud marathon feature.

It is important to note that the reward lottery system in the app is managed by Studio Spoby and is not related to Apple Inc. or Apple Japan Inc. The app is compliant with user privacy and follows a strict privacy policy.
