Are there any communities to peer-review apps in the App Store?

We have just released a goal tracking app a few days ago. We're based in Europe but most of our users come from the US so we would love to get more reviews in the US App Store. Do you know of any communities where app creators review each other's apps and post reviews? It is crucial to get good reviews in the first few days after launch.

This is the app - https://itunes.apple.com/us/app/forward-goals-daily-tracker/id1396009838
