Viewfinder
Viewfinder is a director's viewfinder app for your phone: pick a camera, a lens and an aspect ratio and see the frame on the live camera. Scout a location and plan shots before the kit comes out. It works offline with no account, and stills stay on your phone until you choose to save or share them.
Free includes 3 sensors, 3 aspect ratios, the full lens range and watermarked stills. Viewfinder Pro is a one-time lifetime unlock. No subscription.
