You can make your iPhone or Android contacts automatically sent to your folk workspace by using a Google account connected to both your mobile phone and your folk workspace.
To automatically import your iPhone/Android contacts into folk, you need to:
1. Synchronize all your iPhone/Android contacts with your Google account (Read setup guide for iPhone and Android)
2. Connect your Google account with folk (Read documentation)
Please note that we're only doing a one-way sync from Google to folk. It means that all the changes made on contacts in folk, won't appear on Google nor on your iPhone/Android.
