The current Klok Mobile (Beta) browser app does not currently support starting the timer for a given project on one device and then stopping the timer for that same project on another mobile device. However, Klok Mobile (Beta) can be accessed from any mobile device that uses a modern web browser. This means you’re not restricted to use a single/specific device which gives you the freedom and convenience to track time for your projects using any accessible mobile device with a modern web browser.
