Why it exists

Swim Trainer was created to replace scattered swim planning workflows: notes, screenshots, spreadsheets, disconnected exports, and feedback that gets lost in message threads.

The product focuses on the practical loop that matters in training: plan the session, capture what happened, review the load and technique context, then share the right information with a coach or swimmer.

Product principles

• Structured sessions should be easy to repeat, adjust, and share.
• Metrics such as CSS, SWOLF, TSS, CTL, ATL, and TSB are useful only when they stay connected to the session context.
• Athletes should control what they share, with local-first analysis and explicit collaboration features.
• The app should support serious training without turning every swimmer into a data analyst.
