Productivity tool for work at home, any suggestions ?

Hi everybody,
For years now, i have a side project: develop a tool to facilitate work in general. My idea is a litle cube put in your desktop who assist you to keep concentrated and help you to don't be distracted.
Recently, with the Covid (in any case, in france) lots of employees work from home.
How can this tool make you work better (work in general, from concentration to ability to separate personal to professional life after works) ?

Thank's for your time
