Does the bare minimum. Lists all available packs, but the checklist feature just dims the picture. There is no separate list to show what you have collected or what you're missing/want. Does not list when packs will be available, or if they're exclusive to a store, or what wave they're part of. Also does not allow sorting (such as by pack type or IP series). Would also have been handy if it cross-referenced the checklist with the character list so you could easily see what you're missing. IAP removes ads only, does not enhance app at all.
