Backup Contacts In Address Book - Export As vCard

I've been stressing all morning on how to get solid back ups of my data off my iPhone in preparation for a battery replacement. I'd been warned by Apple that the battery replacement could destroy my data. I don't have iCloud back up and besides, even if I did, I really want a hardcopy! Especially since Apple took away the ability to completely back up /restore my phone in their latest iTunes "upgrade" (doesn't that speak volumes) i've been scrambling all morning. This free app worked like a charm: it allowed me to email my contacts list to myself and I'm looking at it now. The only thing missing appears to be my extra notes at the bottom of my contacts. But I can survive that if necessary! I thanks to the author! The only other app I could find that claimed The ability to do this required iOS11+ -- which I don't have and don't want (it breaks all 32 bit apps many of which I rely on critically). The apple contacts manager on my Mac air immediately opened and updated the download. I don't write many reviews but this one deserves 5 stars in my book... Thank you! Thank you! Thank you! Thank you! Thank you!
