TrendMinerPro - Anyone has used this? Still relevant?

I stumbled upon this app from Jack Duncan and I was told he produced really good software.

So this is the app name : TrendMinerPro

I thought of buying but I can't find any review and I saw some threads talking about this wayback 2013, 2016 , so I just wonder if this app is still good to use? Or any other similar product?

Thanks
