Best I’ve used

I am in sales and collect contact information at a astonashing rate. If I am at an event or conference I can easily collect 50 cards and a lot of other misc. data. My phone is where it gets stuck, and over time it becomes unruly and needs a good cleaning.
I started a new job with a new system, and it duplicated my contacts, and resorted things into a real mess. LinkedIn screwed up my list real good too.
The first de-duplicator I bought doesn’t allow you to fix anything in bulk. Meaning- it pulls every contact and asks what you want to do. I had 7800 contacts- this was an impossible task.
I bought this app and it groups the errors into similar kinds, allows you to determine the logic of fixing that group (merge, delete, delete the bad variable, etc). I’m 20 minutes into the cleanup and have reduced my list from 7800 entries to 1994. It just cleaned up 720 duplicated ‘notes’! Just what I needed! And so cheap compared to the time it saved!
