Apple’s coveted Best of 2019 awards were announced, and iPhone App of the Year was awarded to Spectre Camera by Lux Optics. Coincidentally I tried Spectre recently while photographing the sunset against the Golden Gate Bridge during a Photosprouts landscape photography course.
Spectre is amazing. It allows anyone to capture gorgeous long exposure photos with minimal effort. I also use Halide, the app that allows you to shoot photos in the RAW format and was built by the same team.
