ShareTrack

iOS app + widgets for tracking videos shared between two people across social platforms.

Stack

• SwiftUI · iOS 17+
• WidgetKit — home screen widgets (single-platform + overview)
• CloudKit — sync share events between paired users
• App Groups — shared state across app, widget, and share extension

Targets

Target	Bundle ID suffix	Role
ShareTrack	.thing	Main app
ShareTrack Widget	.thing.widget	WidgetKit extension
Track Share	.thing.share	Share extension

Tracking model

Third-party apps (Instagram, TikTok, etc.) do not expose DM APIs. ShareTrack uses:

1. Share extension — Share → Track Share from any social app
2. Clipboard detection — copy a link, confirm in-app
3. Manual log — Settings → Log a Share

Events sync via CloudKit public database record types: SMWUser, SMWShareEvent, SMWFriendship.

Widget customization

22 themes · 6 layout styles (glass, card, neon, mesh, outline, flat) · accent presets + custom color picker. Config persisted to App Group UserDefaults as widgetConfigJSON.
