Does not work with Macbook
I successfully created a label and easily imported my contacts from the Contacts app.
However when I had created the list and tried to edit the resulting label I was unable to exit the edit mode. Reading the help documents it explained that I had to "dismiss the keyboard" to exit. Obviously this refers to an iPad and I could find no way to simulate this action on the MacBook. Hence I was unable to use the app on MacOS. All the instructions are geared towards iOS. Perhaps the compatibility claim with MacOS on the App Store should be amended?
In addition there did not seem any way to select an address where a contact had multiple addresses.
Finally I could not find a way to select fields for the label and it seems you are limited to the fields the developer has chosen for the label. It might be possible to overcome this by exporting a contacts file as CSV and then editing it elsewhere and importing it into this app - I did not try this as it rather undermined my search for a simple solution.
I would have liked to ask the developer for help but could find no way to do this easily so have requested a refund and deleted the app.
