Therapy & Physical Training Timer

To set an exercise timer on Free Therapy Timer, define your work duration (the active exercise or hold period, e.g., 30 seconds for a wall sit or isometric hold), your rest duration (recovery period, e.g., 15 seconds), and the total number of sets. Next, select your countdown interval frequency (such as every second, every 5 seconds, or milestone alerts) and preferred voice language. Click Start to begin the audio-guided workout.

Yes. Free Therapy Timer is a 100% free online workout and therapy timer app accessible directly in your web browser with no download, paywall, or subscription required. It runs smoothly on mobile phones, tablets, and desktops, offering spoken countdowns, interval programming, preset routines, and an integrated digital stopwatch.

An interval timer is a specialized timing tool designed to alternate between periods of high or moderate physical activity (work intervals) and periods of recovery or lower intensity (rest intervals) across a predetermined number of cycles (sets). It is widely used in High-Intensity Interval Training (HIIT), Tabata, physical therapy rehabilitation, and circuit conditioning.

An interval timer operates on a cyclical countdown mechanism. Once started, it counts down the active 'Work' phase, alerts you when the interval completes using audio beeps or speech synthesis, automatically transitions into the 'Rest' recovery phase, and repeats this sequence for your chosen number of sets until the session is complete.

Yes. You can set up an interval timer directly on any smartphone (iOS or Android) by visiting freetherapytimer.com in your mobile browser. The website is fully mobile-responsive and functions as a Progressive Web App (PWA) with full touch support, background audio announcements, and responsive dark/light mode controls without needing app store installation.

Using a workout timer maintains consistent workout pacing, eliminates distractions from manual clock-watching, enforces structured work-to-rest ratios, maximizes metabolic conditioning, and ensures strict adherence to clinical rehabilitation protocols (like exact isometric hold durations in physical therapy).

A digital stopwatch displays time formatted as Minutes : Seconds . Centiseconds / Milliseconds (MM:SS.CC). The first two digits represent elapsed minutes, the middle two digits count seconds (00 to 59), and the final two digits measure fractional fractions of a second (hundredths or thousandths). On our stopwatch, lap split times also display the total elapsed duration and delta time for each specific lap.

A stopwatch is a handheld or digital timekeeping instrument engineered to measure the precise amount of time that elapses between its activation (start) and deactivation (stop), often down to hundredths or thousandths of a second.

To use our digital stopwatch, click Start (or press the Spacebar) to begin tracking time. Click Lap (or press L) while the timer is running to record intermediate split times without interrupting total elapsed time. Click Stop to pause timing, and click Reset (or press R) to return the clock to zero. You can also export recorded lap data as a CSV file.

A stopwatch is used in athletics for timing sprints, laps, and swimming trials; in healthcare and physiotherapy for evaluating patient mobility, balance holds, and gait speed; in laboratory experiments; and in productivity techniques like timeboxing.

A stopwatch measures elapsed time—the exact duration between a designated start event and a stopping point. Unlike a standard wall clock that displays time-of-day (hours and minutes), a stopwatch measures time intervals with high precision (centiseconds or milliseconds).
