Swim Note is an iPhone application designed by MASAO SOTA for tracking swimming training activities. This app allows users to easily manage their workout records, whether inputting detailed information or just the distance covered. Users can save workout templates, reuse previous records, and customize style and distance selections. Additionally, Swim Note offers features such as sharing workouts via Mail/Twitter, graphically viewing workout history, saving photos, exporting to the Health app, and generating CSV exports (Add-on required).

Swim Note also includes functionalities for managing swim meet records, providing graph views of time records, saving photos, sharing results, and CSV exports. Furthermore, the app offers a unique "Where am I?" feature that displays the cumulative distance of training records on a map, allowing users to visualize their training routes between two locations. Users can change start and goal locations and select different cumulation methods like within 1 year, 30 days, this year, or all data. Other features include support for multiple swimmers and team management, workout and swim meet statistics display, and a calendar view.
