If you took a glance at drupe's Recents view, you must've noticed it was quite different than your ordinary call log.
drupe offers a unique, unified action log. It collects all of your recent interactions with your contacts, regardless of the app you used - whether it was a call, a Facebook messenger message you got, a WhatsApp message and more.
drupe's Recents view is filtered per contact rather than per action - a contact's Recents entry will only display the most recent interaction you had made with them.
