Localplus app for iPhone and iPad

Localplus provides a location-based platform that allows users to freely search or post items and communicate directly with each other.
You can join Localplus with a pre-existing Facebook account. Once joined, you can manage your existing posts or submit new posts through the My Posts section. A post is location-based and is visible on the map, and its contents can be anything from used textbooks to sublet information.
You can also perform search in the Search section. The search will return you with a list of posts that satisfies your query criteria and will take into account your current location so you can easily find things locally.
If you find a post that interests you, you can simply message the owner within Localplus.
