SciNote does not have a timer feature that would record time of e.g. task execution.
However, you can use Complete step (image 1) or Complete task (image 2) buttons inside individual tasks and the completion of a task is time-stamped under the ACTIVITY tab (image 3).
By calculating the time between first and last completion of a step, you can get the information of time spent on specific tasks.
