Yes, you can do tasks that involve your contacts. There are 4 types - meeting, call, SMS or Email. After selecting a task (called event in the app), you select which contact(s) it applies to. It will then be saved in the history of that contact, while also appearing in the Events tab until it's complete.
You can try out this function for a few events for free in the free version of the app.
