## Changelog

- 2026-10-07, Correction: Recalculated rank changes against April 2026. 9 of 30 original figures did not match the ranks published in that edition, so every value now compares against it. Apps not in that list show as new.
- 2026-10-07, Correction: Rewrote the takeaways from this edition's data. The original text repeated the February 2026 edition, so its apps and figures did not match the table on this page.
- 2026-10-07, Update: Moved from toriiresearch.com; title standardized. Torii Research now lives on toriihq.com. It was first published as "Adoption Index Report: May 26" at toriiresearch.com/reports/adoption-index-report-may-26.
