Honestly very frustrating to use. It's just the mobile website, in app form. There is nothing the app improves upon over the website, and in fact there are many simple things the site can do better. On the site, you can copy/paste, open multiple listings in tabs, and use your browser's automatic translations to make communicating and viewing listings in other languages easier. The app can't do any of that, and offers nothing to replace it, so you're better off just using the mobile site.
