Native is a relationship, not a release claim.

Tare is the app that gets opened every day, and the one carrying the most history, so the native version was built to hold that history without asking for an account at all. The retired web app used Microsoft sign-in; the native app keeps everything in SwiftData on the device and syncs through your own private iCloud database. After you opt in, it imports approved Apple Health data whenever the app opens or returns, while a manual Sync now control stays available. It also adds widgets, a dose-day Live Activity, Apple Watch logging, Siri, Face ID and local reminders. A compatible backup created before retirement remains a migration path into the native store.

ShopKeep 2.0.1 (35) is a valid attached private build for iPhone and iPad. The native client adds camera-first scanning, widgets and Siri, while Apple and Microsoft sign-in reach separate account-backed workspaces. Photos and documents load only through authenticated private-media requests, and Account & Data can permanently delete only the selected provider workspace after server confirmation.

Cairn is fully standalone: there is no sign-in, Nintek server or app-authored network call. Progress stays local and can sync only through your private Apple iCloud database; it never syncs with the web app. The current build includes bundled exam and course material, but rights and attribution remediation is still pending integration before the rejected release can be resubmitted.

Watchtower owns infrastructure monitoring, observability, alerting, and operations, including the compatibility API consumed by its private iOS companion.
