Adding contacts into Enudge, when you are at a networking event or out meeting a new prospect is made super easy with the Enudge Contact App. You can tailor a consent statement which will appear at the bottom of the 'Add Contact' screen, to allow you to show this screen to your contact as part of the subscription process. Or you can turn off the consent text altogether. As you add your new contact you can choose from previously used categories, or add a new category on the fly, helping support the segmentation of your database for attachment to your future email and SMS campaigns. You can add all the information about a contact, or just their email address / mobile number. The Enudge Contact app allows you to setup to send contacts into multiple Enudge accounts. Just add another license, and then as you add contacts, you can easily switch between accounts. The currently selected account is shown clearly in the top right hand corner of the screen at all times, to help you ensure you are adding your contact into the correct database.

Verdict
The clearest difference is update cadence: Sine Pro at every 3 weeks against Enudge Contacts's every 6 months. Enudge Contacts's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
