yco Contact is a contact management app. It organizes device contacts in groups independent of contact accounts in the device. This can avoid confusion of contact groups when there are multiple accounts (e.g. Google, Facebook, WhatsApp
etc) in the device, especially different device manufacturers have their own way of mixing the contacts from different accounts.

The app also serves to backup device contacts to multiple profiles such that important contact information can be recovered in case of loss of contacts for whatever reasons. Changes in device contacts are automatically copied to specific profile as well. Backup contacts can be restored to the device or another device using this app. The app also support selective restore of contacts from individual profile.
