How the studies were built
- Primary sources only. App Store and Google Play listings, makers' own pricing and help pages, newsrooms and blogs. No third-party review sites.
- Every value sourced and dated. Each cell in the datasets carries its source URL and the date it was read (4 November 2026).
- "Not published" is not "absent". When a maker does not describe a feature, the study records it as not published, not as missing.
- No hands-on tests. These are desk studies of what makers publish. We did not test the apps or measure accuracy.
Both studies are published by Alegria Media and Consulting Ltd., which also publishes this site. Corrections are welcome through the contact page.
