Swapviva, allows you to trade products and services with other Swapviva members. This is a great FREE bartering service. Its like a newer, more advanced, modern day Craigslist.
Once you launch the app you will want to sign into your Swapviva account or create a new account. Once you have an account set up you can quickly see what others have for sale or to barter. You can also use the search function to quickly find what you are looking for using specific keywords.
The controls are very easy just click on the tabs at the bottom to see your items, add a new item, or access your profile.
With your iPhone camera you can quickly take a picture and post anything very fast. Unfortunately you are only allowed to post 10 items for FREE. Once you have posted your items, other Swapviva members can search your items and make offers using items from their inventory to trade or simply pay you in cash. You will them have the option to leave a comment and accept or decline the offer.
Swapviva is currently a free application. Right now there are just a limited number of people using the app, so share it with friends and this could come in very handy to replace Craigslist and eBay.
