It's very easy to use, it has all of my important contact info at hand for quick reference. I love that you can add notes/emails directly from an email or text message which is so convenient! The ability to quickly create new tasks & assign them out as well as send emails are also great features! Creating invoices have never been easier than using this app along side Quickbooks Online (which i don't like). Nothing really - just keep up w/the updates because they've made some changes recentlyβ¦
