There's nothing in the LGPLv3 that prevents you from charging money, or distributing through app stores, so long as you comply with the requirements of the license.
The issue is App Stores with DRM do conflict with the license. Though I think LGPL could be appeased by posting the code on a public website, but that might actually be a conflict :)
Apple certainly has a strong policy against GPL and LGPL on their store since it the store can not be compatible.
