Don't watch it on your eye-pod. You're missing the point in that case. That little "screen" won't flash your eyes worth a damn. And then, oh look: there's no visual entrainment. Then it's only auditory entrainment, and that's only half as effective.
What you do while using it is optional, but if you read the page, you'd know at least some of the things you could do in order to strengthen your visualisation skills. I ask you to go and read the page the again, because if I didn't know any better, you just skimmed the entire thing and jumped straight to the download links and grabbed... Constant Alpha... because Makeshift found it useful. Yeah, seems to me you didn't read anything. Not that I really know, but your uninformed views reflect such a guess. How much you can or should use it is also something I explain on the page.
Shapes and colours are probably the only things your supposedly weak visual cortex can work out because you're likely not used to hallucinating anything (are you?), so phosphene imagery is the next-best thing you're probably gonna be seeing for a while.
Also pretty hilarious to hear you're gonna use it in the weekend "because there's more time". Like those kind of people that go all "Man, I'm gonna make a tupper during summer because then I'll have time for it." because their daily schedule is packed up with vidya and "studies" and what do you know, even though those people in many, many cases have at least an hour to set off for work on a tupper. They just can't be arsed. Eh, anyway, I guess I shouldn't be too assumptious here, but it's familiar, you'll have to agree on that.
