Anyone using software to track your VA's productivity?

[Brian Jordan]

I have 2 full time VA's but often wonder if they're working all the time. I didn't hire them through a company, such as Upwork, so I have no tracking abilities. I've researched a few and found one called Hubstaff. Does anyone have experience with them or any other tracking software? It provides incremental screenshots, time tracking, activity levels and a list of URL's they've visited while on the clock. Any help is greatly appreciated!
