 RecommendedPros: 

A great collection tracker with what I consider is the best free card scanner in the appstore. Devs deliver updates constantly.

Cons: 

Is still in development, there are some minor bugs and issues.

My Review will cover only collection tracking since is the only use I cureently give to Mage. Any deckbox.org, mtgcollectionbuilder or mtggoldish user should consider giving it a try. You can export cards easily and offers a comfy interface for consulting, sorting and brewing.
