Make My Day is an app that plans optimal routes for daily errands based on factors like distance, traffic, and business hours. It analyzes user data like scheduled errands to provide customized routes that are more efficient than how people currently plan errands. The app works by allowing users to choose their errands, then receiving a scheduled route for the day. Make My Day's business model is license-based, charging $10 per car to partner companies in areas like automotive, navigation, and retail to gain access to the app's big data and user base. This could generate over $880 million annually from the 88 million cars sold globally each year.
