Which package to buy?

[Azhrei]

Hey all.

I want to buy a package that contains everything needed for easy use of the Summon Monster tables. It looks like the Summoner's Pack has that (for $6, on sale).

But it mentions "everything needed from the Encounter Library". The iPad app, which is what I use at the game table, doesn't have an "Encounter Library". Will this pack be usable in the iPad app?

If not, should I consider the GM Bundle instead, which includes five bestiaries and a couple other books? Or would that work the same way and require the encounter library?

I want to pick up what I need while it's on sale, so if you know the answer, please reply. Thanks!
