Keeper has one problem though, it's rated a 17+ (or 12+?) so for those who have their App Store set to 4+ as part of their filter, that'd be a bit of a problem.
Yahoo Finance, eBay, and a few others have the same problem. (not exactly sure why Apple decided that Twitter is more age appropriate than Keeper, Yahoo Finance & eBay... But that's a whole different story
)
The workaround I do is i set the App Store to "allow all apps" and then disable the ability to download (new) apps altogether.
