5BX Tracker Changelog

1.0.0 - 2026-04-30

Added a Progress-screen data export button that downloads all 5BX tracker data and workout history as a JSON file for backup and portability.
Added reset access on the Progress screen so users can clear all saved data from the same place they review history.

Fixed the elapsed timer so it correctly accumulates time across page reloads. Time spent with the page closed is not counted; on resuming a mid-session workout the timer picks up from where it left off.

Fixed the elapsed timer so it starts as soon as the first exercise is shown, rather than waiting for the first Done click.

Added a Progress screen showing current chart and level, age-appropriate target, an overall progress bar (level out of 72), days at the current level, estimated target date, and a full workout history list.
Added a Progress button to the workout, active exercise, completion, and congratulations screens. From the Progress screen, a Today button returns to the current workout state.

Added an "Advance to next level" button on the completion screen, shown once the minimum required days at the current level have been completed.
Advancing resets the days counter, moves to the next chart level, and marks the session as advanced in the workout history.
Reaching the age-appropriate target now shows a dedicated congratulations screen and switches the tool to maintenance mode (three workouts per week).
Completion screen now shows a maintenance mode banner when the user is already at their target level.

Added reference diagrams to each exercise card during the workout, sourced from the RCAF 5BX programme. Each chart's five exercises now display the correct illustration.

Added interactive workout screen that guides users through the five exercises one at a time, with a Done button and progress dots showing position in the session.
Workout data is persisted to localStorage after each exercise. Returning mid-session resumes from where you left off; returning after completing all five exercises shows the completed state.
Added elapsed timer that starts on the first Done click and shows total session time on the completion screen.

Initial release: onboarding flow with age entry, three-step programme explanation, fitness assessment questionnaire, and manual level selection. Displays the full exercise list for the chosen starting level with rep targets and descriptions. Full programme data hardcoded for all six charts and twelve levels.
