I am a smartphone fan, I have used Windows Phone, iPhones, Androids and many more devices.
Each platform requires different accounts, for instance Microsoft requires a Hotmail account, while Android requires Gmail etc.
Over the past few years what I started to notice is, my contacts are being duplicated and some of the Hotmail contacts don't exist in my Gmail account and vice versa. It became a nightmare.
I am looking for some tools that will help me manage/sync my contacts and make sure they are not duplicated.
It could be an app or an application for Mac or Windows, I dont really mind.
