Roger Fingas, AppleInsider:

When users tap the button to listen to a song, the app will now save a sample for upload when internet access returns. A notification should pop up once a result is ready. The Android version of Shazam previously had equivalent offline support.

“Apple’s Shazam”. Weird to hear, but yup, Shazam is now all Apple’s.

Smart addition. Glad to have this in iOS.
