How do I focus?

I've been working on an app that utilizes this user interaction, and what I've come up with is double tap to take a picture. Don't focus until you're sure there's no second tap (a few hundred ms). Or you could always just add a simple camera button, which solves this problem.

I've assumed that "Tap to snap..." works on the (right) button area only and tapping the photo triggers focus. This isn't clear though.

Thank you for the feedback. I hadn't thought that it could be interpreted that way. The idea is that it tapping and holding for photo/video works anywhere on the screen. I also would like it to focus on tap (shooting = focussing)
Would this not be equally useful just triggering the standard iOS camera? Tap to focus, volume buttons and a large shutter button take photos.
The feature is supposed to be built into other apps like whatsapp, Instagram or Facebook messenger. From there it offers a faster experience than jumping to the iOS camera. It is also faster than aiming for buttons to get to the apps' camera.
I'm assuming autofocus is so good these days, for snapshots you can live without it. Another option would be that focussing and the shutter are the same action.
What's the name of the app? I'd love to see it.
