This app helps users manage swimming training sessions, course records, and workout progress in a simple and organized way. Users can record swimming distance, duration, calories, stroke type, and training notes, while tracking daily check-ins and long-term exercise habits. Built-in statistics and visual charts provide weekly and monthly summaries for training distance, workout time, and performance trends. The app also supports course scheduling, coach information, and training management for a more structured swimming experience. All data is stored locally on the device, allowing the app to work completely offline while offering a smooth, private, and reliable training management experience.
