I don't mean to be rude but those things aren't effective future reading devices.
You know how some people have dreams about things that happen a few weeks later? That means that they're seeing the future. However, it's always very different, which means it's more like a rough prediction. It's like, "If everyone acts like we expect them to, it'll be like this," but since we have free will and often do unexpected things, it's slightly different in real life. Our free will keeps the future fluid. It's more like an estimate of our personalities, which are always changing. No method of future reading is effective since it just suggests what might happen.
Anyway, I believe it's a sin to even try predicting this stuff, so I stay away from it.
