Contacts Features List

Allowing EasilyDo to access your contacts will allow EasilyDo to search for duplicate contacts within your list and offer to merge them. 

EasilyDo only merges contacts that are within the same group or source. What this means is that EasilyDo will never merge contacts for a name that exists in your Gmail contacts and also in your Exchange contacts. The app will not offer to merge these so that you can maintain your separate contact lists.
