Apple is set to launch an iOS update tomorrow, the company announced on its Twitter feed.
Apple said the update will add support for the new iCloud Photos app and iCloud Drive.
It will also bring the ability to delete photos from your iCloud account.
The new update will arrive as an incremental update for iOS users that have a device with an iOS version of 10.3 or later.
The iPhone 5s and later and iPhone 6s and 6s Plus will be able to receive the update on April 15.
Apple did not say when the update would arrive for the Mac.
Apple has been quietly working on iOS 7 since last spring, but its release date has been pushed back several times.
