A share extension lets an iOS app receive content from other apps. SnapAction currently uses App Shortcuts, Action Button, and Control Center widgets instead of a traditional share extension.
A share extension is an iOS feature that lets apps receive content from other apps through the system share sheet.
How share extensions usually work
When you tap the share button in Safari, Photos, or another app, the share sheet appears with a list of apps that can receive the content. A share extension lets an app appear in that list and process the shared item.
SnapAction’s approach
SnapAction does not currently provide a traditional iOS share extension. Instead, it uses:
- App Shortcuts for quick screenshot scanning
- iPhone Action Button for instant latest-screenshot capture
- Control Center widget for fast access
- In-app PhotoKit gallery selection
These entry points are designed for the screenshot-to-resource workflow specifically, rather than general content sharing.
Future possibilities
A share extension could be added in a future update to let users send images directly to SnapAction from the Photos share sheet. For now, the app focuses on PhotoKit-based scanning and widget shortcuts.
When a share extension is useful
A share extension is useful when the user is already inside another app and wants to hand off content immediately. For example, someone might send an image, URL, PDF, or text snippet into a read-later app, note-taking app, or automation workflow without switching contexts.
For screenshot workflows, a share extension is only one possible entry point. Some apps may prefer direct Photos access, widgets, shortcuts, or an in-app picker because those paths can be more specific to the job. The right entry point depends on what the user is capturing and how quickly the app needs to process it.
