I've tried to use monica and make it work but I find it's a product that doesn't fit with my needs and lacking a lot of simple and useful features. For example, you have to manually import contacts. You import your 600 contacts and you can't even bulk remove /edit contacts. You're stuck with this huge list of contacts from your phone. Just the simple things such as bulk editing contacts are missing. So you end up with a list of contact on your phone / email, in addition to monica and it all ends up out of sync. I want one source of truth for all my contact and people I want to remain in contact with. With everything synced: CRM, phone, email contacts, etc.
