I’m really impressed with the contact sharing feature, it’s fast and eliminates the usual hassle of manual entry. What stands out most is the AI powered contact creation, which accurately fills in details and saves so much time. It feels intuitive and smart, making networking smoother and more efficient. Definitely a feature I didn’t know I needed!

Great tool with one HUGE flaw: It rejects suspicious or spam messages, but Google often flags normal emails as suspicious, although I am in frequent communication and those emails are even marked as improtant by me. Yet this app refuses to read contact details from these emails.

A few extra features I would include, such as importing from Google Contacts and doing the merge and clean inside shared contacts, plus the ability to add/remove fields to configure the contact screen to capture information important to you / your business, would be great. If I can do this, I'd like to know how. This application helps share contacts with all users/staff who need contact and other details. Now, we need to train/remind users so they can also add contacts. I am surprised this is not built into Google; it is what is required in order to unlock its powerful simplicity. Thank you.

Apparently this is Trial software even though I don't see where it discloses that anywhere. Zero stars. I would rate it negative if I could.

This app has made collaborating on contacts so much better for us and sharing these contacts with any other person is as easy as one, two, and three! I only have to create a label and then click on the share button, next thing is to enter the email address and set the permission I want that person to have, and that is all. All the new contacts I add to the shared label are automatically shared and synced with their mobile phones. Fantastic work!

Sharing contacts for our law firm has been one of the biggest pains and we were using Office exchange, which has its own limitations. One of our colleagues suggested we contact this company to see if they can help us in any way, considering we are not using Google Workspace. In the very first call, their team smoothly guided us on what needs to be done and we were on-boarded on migrating our contacts from Office to Google Workspace, partly because it was better for us and partly because they offered us to do the migration on our behalf. Once they successfully migrated our contacts, they helped us understand how we can make the most out of their web application, extensions and mobile apps. We organized our contacts in labels and this app gave us powers to share these contacts with anyone in our team or anyone else who is using Gmail. In addition, our contacts list is automatically updated every time any member makes any changes to the shared contacts. Their company and the services they offer are exceptional. They apparently give you power to share contacts, but they actually help us do so much more!

Sharing contacts with this tool is super easy. We share our contact labels of our church with our team members and other event organizers, despite the fact that these are not on our domain. We can even share these contact labels with any Gmail user as well. This is really powerful and extremely versatile and intuitive. We are big fans and we recommend everyone to try it!
