What are the limits of Workout Interval Timer?
An interval clock, not an exercise program or intensity recommendation. Up to 30 rounds and two hours. Choose activities and intensity appropriate for you. Timers pause when the tab is hidden to avoid silently skipping stages; browser audio is optional and not a guaranteed alarm. Inputs and logs stay in page memory. No account, upload, health-data analytics, browser storage or medical-record synchronization. Leaving or refreshing the page can clear the session; explicitly downloaded files contain your information. Exports are local PNG/PDF summaries, CSV schedules or logs, and a sleep calendar where offered. These tools are for general planning and estimates, not diagnosis or individualized treatment.
