Which of the tools would you recommend to optimise the use of time?

If you work with small or complex projects and people, then you'll need a management tool with the time management feature. I'd suggest to try GanttPRO https://ganttpro.com/. This tool helps to track time spent on project tasks by team members. You can start the timer in real time or log it afterward.

I recommend TMetric time tracking app - a perfect solution to capture time, see where it goes, and analyze its utilization for optimization and better planning of the workload.
