Apple has updated three of its iPad apps: Numbers, Keynote and Pages. The improvements are probably related to the upcoming iOS 9 update to provide better compatibility. The official notes state only that the update contains stability improvements and bug fixes.
These apps allow you to create reports, presentations and work with spreadsheets. They work seamlessly with iCloud. Your documents will be up to date on all devices. You can also collaborate with others by sharing links to the documents. Others do not need to have the apps to work with the documents. They can work from a browser.
