That depends. Photofetcher autonomously evaluates all the photos in a user’s device library or cloud. Photofetcher will alert the user when photo analysis is complete, and the results are ready for review. If automated services, like photo book printing, are part of the user service plan, the app will notify the user and wait for a pre-set amount of time for the user to review evaluation results before triggering any automated process or service. The actual time needed to evaluate depends on the number of photos. On a device with a high-speed internet connection; the photo evaluation, curation/selection, and A.I. commentary processes for 10,000 photos will take on average 4-5 hours.
