Invidyo contains a powerful face recognition system that enables it to distinguish familiar and friendly faces in your household from strangers. However, it cant do all this on its own, it initially needs your help to get acquainted with the familiar faces.
Let's help invidyo by labeling the unrecognized faces. Just tap one of the faces to switch to multiple selection mode. And then tap all the faces that were marked as unrecognized.
Now tap Label on the top. You will see a new screen that allows you to label the faces you just selected as one of the already existing people or add the selected faces as a new person. Either click on the person's face or click select to mark selected faces as one of the existing faces. Or click Add a New Person to add them as a new person.
