Caller ID provides you with a way to identify outgoing or incoming calls from unsaved numbers. When someone calls you from an unidentified phone number drupe's overlay will appear with the person's name (if recognized).
drupe's database is growing every day using a learning algorithm and with the help of our great community. If you find a mistake in a number identification, call that number and hang up. On the 'After a call' pop up, tap 'Suggest a better name' and correct it.
