Challenge

Preserve useful vocabulary across connected AI conversations without retaining entire conversations.

Constraints

The iOS app and language plugin have separate releases. Provider support remains scoped to explicitly connected flows; broader device and accessibility acceptance remains open.

System

The iOS app combines a private My Lexicon with pronunciation, listening, and review tools. Connected AI providers use scoped, bounded teaching context.

Magneum’s contribution

Built and released the iOS app and product site, including guided connection and demo flows, privacy notice, terms, and support.

Verification

Apple’s US listing reports version 0.2.6 with Magneum Industries LLC as seller. GitHub publishes language-plugin v0.3.8. The product site and demo page were reachable on October 1, 2026.

Outcome

A public iOS release, product site, and demos give customers a way to explore YipYap and its My Lexicon workflow.

Limitations

The App Store listing does not prove every provider or device and accessibility path. The GitHub plugin release does not establish directory publication or installation on a customer device.
