Best app Ive found for composing shots with a phone, along with storyboarding on location scouts.
Ive used this for weddings and narrative films, and its been great to be able to share references with the crew and not need to lug around a backpack with 4 lenses.
The other 0-3 star reviewers arent giving it the credit it deserves. There have been a couple bugs in the past, but the point is that it works when I need it to, and its more powerful than any other viewfinder apps out there.
This does 10x what a real directors viewfinder does, and for a fraction of the cost.
No brainer.
