Mobile release history
This page records mobile-app releases only from publicly verifiable store metadata. Website, dataset, translation, research, schema, and Agent Skill changes belong to the public-site changelog and do not become app releases merely because Git had an energetic day.
Store metadata rechecked:

* Some localized Apple storefronts display the 3.1 and 3.0 dates as “3 Mar” and “26 Jan” without printing the year next to the version. This page normalizes those dates to 2026 from their position after the explicitly dated 8 Dec 2025 release and current storefront chronology.

Google Play
The public Google Play listing for package cbt.cbtcards.stressrelief was shown as updated 9 March 2026 when rechecked on 19 August 2026.
The retrieved public listing does not expose a reliable Android version name or version code. This page therefore does not label the Android release “3.1” merely because the iOS app had that version nearby in time.
