It looks similar to https://timeular.com, which I tried for a few weeks in 2018 or 2019. My thought was cool but unnecessary. My main take away was my time was too fragmented. While devices like this can categorize and quantify how much time we spend when we jump from one thing to another, it makes more sense to not jump around from one thing to another. I just refer to when I do this as "un categorized work time" or "un categorized personal time".
