I love this app from the second I opened it and started importing my contacts. I work with CRM systems daily. For a couple companies. And I hated uploading my hard earned relationships into a corporate CRM, but thats all I had access to. This app took my 2500+ contacts and allowed me to build my own Follow up / Engagement Campaign. This is huge in my business of Residential Mortgages. My only draw back are the corky bugs I.E. If in in the app and phone call comes through. App crashes after return. Photos every so often appear on different contacts, but adjust back when you open the contact. Through me off a couple times. Never the less over all great app and is destined to be perfect. They should also add customizable emails templates. Making follow up button easier.
