Sport Zone Builder

Sport Zone Builder is an offline training tool for athletes, coaches and multisport users who want to organize effort zones, fitness tests and structured workouts in a clear mobile space. Set up disciplines, choose distance units, define effort scales and save training data locally without internet access.

Create control tests for running, cycling, swimming, rowing, skiing, walking, mobility or custom disciplines. Add details such as date, duration, distance, average pace, heart rate, power, effort level and notes. The app validates entries and recalculates related sport zones locally after each saved test.

The zone map shows the disciplines in simple vertical sections. For each discipline, you can review the effort zones, pace or power values, heart rate data when available, date of the last test and accuracy status. You can also edit zones manually, recalculate zones from a test, or hide disciplines you don't use.

Sport Zone Builder also includes a workout builder to create sessions from blocks such as warm-up, main block, recovery, and cool-down. Each block can include a discipline, zone, duration, goal, and notes. The summary shows your total time by discipline and zone before you start your workout.

History and analysis screens help you review your saved tests and workouts by discipline, month, or zone. Open any record to see the original fields, calculated zones, notes, and actions to edit, delete, or duplicate. Empty states explain what will appear after your first saved test or workout.

With a lightweight interface, local storage, reminders, export to text, privacy controls, and simple navigation, Sport Zone Builder helps organize multisport training, heart rate zones, pace zones, power zones, and training load review in one convenient offline planner.
