The most useful feature I like is that it makes my social media profiles more organized, so i can easily access them from anywhere using mobile devices or web browsers without having multiple accounts for different platforms (Facebook/Twitter). It's also very easy to use! Nothing at this time but if you're looking into organizing your contacts in one place then definitely give conveyapp app a try - they have free plans as well which allows me to test out their features first before purchasing paid plan. I love that you can search by last name in order to find people from your network. It's very easy to use and it's free! The only thing that could be improved is if you could add more filters for people you know. I'm sure there are some other features they could add, but this one is perfect! I've been using ConveyApp for years now and have never had any problems with it. I am always trying new networks and this has helped me connect with so many different professionals.
