Motus - Business Mileage Log is a productivity app designed for iPhone users to efficiently manage their business mileage logs. With a subscription to the Motus service, users can modify their mileage records from anywhere, ensuring compliance with IRS regulations. The app automatically generates and saves mileage logs in the cloud, providing users with peace of mind during audits. Key features include the ability to add, edit, or delete trips, submit mileage for reimbursement, and access comprehensive monthly mileage history.

The app also offers GPS functionality for users whose employers have enabled it. This feature allows for automatic recording of business stops and trip mileage, along with detailed location tracking. Users can set business hours for automatic tracking, view routes on a map, and receive push notifications for mileage input. While the app minimizes battery usage, continuous GPS tracking may impact battery life, so users are advised to charge their devices while driving.
