We studied 16 health-and-fitness apps with vision-covered authentication screens. Email was offered by 11, Google by 7, Apple by 5, guest mode by 4, and phone/OTP by 3. Compared with a 289-company corpus, the corresponding prevalence figures are 72.7%, 48.8%, 43.6%, 21.5%, and 26.0%. Counts for the 16-app sample are absolute, and visual detection may miss methods not shown in a screenshot.
