Dex for iOS and Android

It is super easy to use; it automates all the hard work of synchronizing my LinkedIn, Google, and others tools I use to manage my contacts. And it allows me to take notes during meetings. I really like the user-friendly interface, and knowing that I can easily import and export my data. I also noticed it speeds up the process of saving contacts on my mobile phone, as whenever I save a new contact with whom I am already connected to LinkedIn, I just need to add the phone number. And when I save the contacts from some WhatsApp group chat, I don't even need to add the phone number.
