This needs Android 4.4 so not all phones can install it.

This is what HTC says about it. Blog post from HTC on it HERE
Zoe is a simple way to create, share and remix professional quality highlight videos—and it’s even better when your friends pitch in. Choose the photos and videos you’d like to share, add a filter to give your highlight video a unique look, and choose the perfect soundtrack. Bring shared moments to life by inviting friends to remix your video, and remix theirs! Remixing lets you to add the best photos and videos from everyone who was there to create the ultimate highlight reel.
Zoe enables you to capture, share and remix the most important, fun, precious and whimsical life moments with the world.
And being a Beta, perhaps not all things in it are final yet. And, you need Android 4.4 for it. And you need a HTC account for it, which us with HTC phones already got.
There’s a site for it as well https://www.zoe.com/
