I'm frustrated that app builders who offered a free app are allowed to offer an upgrade at a price amongst free upgrades. To avoid accidentally incurring a charge, one must click each and every app, and go to the page to see if it's free or not. This is dishonest!! Not only are "free" or "pay" not shown on the upgrade page, but there is now way to remove or flag these. There needs to be a way to hide unwanted upgrades, as well as an "upgrade free only". A classic case is Tunein Radio, a free app, that offers an "update", which in fact is an "upgrade" to a paid app for about $5. There are several others. I feel like I'm being conned in hopes that I'll click the "upgrade all" button. This is a dishonest business practice and needs to stop. It is one thing to offer an upgrade from the app page as Pandora does, and quite another to attempt to trick customers into unwittingly spending money.
