Hey guys,
How did you expose your app to the larger crowd? I am now reading about app reviews websites, are they worth it?

What you're describing is a marketing channel.
There are innumerable ways to get your message out and build all kinds of complex strategies. I'd be careful garnering ratings through app review websites unless I was 110% confident in the quality of the product.
The last thing you want is a load of negative reviews because it wasn't ready.
Paid advertising is considered the holy grail as it is incredibly repeatable. If you can spend x and make a profit, you just scale up your spending (obv not this simplistic, but you get the point).
I'd suggest asking some questions on an internet marketing forum and consulting with an experienced marketer. This will surely help you form a solid plan from the beginning.
