It's a pretty decent app, but there are many other apps on the Play Store that are better than this one for managing contacts. The main issues I've experienced with this app are: 1. No option to save a new contact to all of the accounts I've configured on my phone to sync its contacts (e.g., Outlook), 2. The app fails when identifying and when merging duplicate contacts, 3. The postal address is not saved in the defacto standard format for contacts, 4. Field labels are not language-independent.
