ObscuraFlex is a camera app designed for use with the ObscuraFlex™ large format camera viewfinder adapter for cameras including 4x5 Graflex, Linhof, Chamonix, and some vintage Polaroid cameras. The app provides a high resolution live feed of your large format camera's image plane (ie: ground glass) rotated to reverse the upside-down image created by any traditional optical system. When using the camera adapter as a composition and focusing aid for large format film photography the ObscuraFlex™ provides a greater level of detail and clarity than working with a standard ground glass, and with an image that's right-side-up! You can also use the adapter with this app (or other camera app) to shoot stills, video, or reference images to accompany your film negatives.

Verdict
The clearest difference is review sentiment: ObscuraFlex at 100% against Colorimeter's 0%. ObscuraFlex also leads on price (Free vs $0.99) and update cadence (every 5 weeks vs every 86 months). Colorimeter's advantage is iOS requirement (12.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
