The below is where to add a new contact. See the screenshots.
The recipients of you will be automatically added in the “Contacts”. You can also save the senders to the “Contacts”. You can also manually add contacts or scan QR code to add contacts. The “Contacts” are arranged in alphabetical order.
MeSince uploads and backups your “Contacts” to the cloud server by default, so that you can synchronize the “Contacts” when you install MeSince on a new device. In cases that you lose your phone or change a new one, it will be more convenient to retrieve the contacts because they are not in any phone’s cloud.
Of course, you can set not to save the “Contacts” to the cloud server.
