Delivery Status Touch has been update for iOS 7, with a refreshed interface and some iOS 7-exclusive features. Background notifications are supported, letting the status of your packages update when the app is closed. AirDrop sharing lets you share your package status with others around you. You can also share deliveries with via SMS or iMessage. Barcode scanning is also faster on iOS 7.
But there are more features that can be accessed by every user, not just those running iOS 7. Calendar support lets you add estimated delivery dates to your calendar if you want. Turn this feature on in Delivery Status' settings under Notifications. You can now archive your deliveries, rather than deleting them. You can now sync with iCloud, and your favorites will now sync with iCloud even if you use Junecloud to sync the rest of your data. 1Password integration lets you easily look up your passwords.
This update is available now. When you grab it, let me know what you think!
