Microsoft OneNote for iPhone has been updated with support for the iPhone 6 and iPhone 6 Plus, along with enhancements to security. These include better password protection, and Touch ID.
Touch ID allows you to unlock items that are password protected with your fingerprint. You can now also create new password protected sections. You can even change or remove the passwords on existing protected sections.
OneNote will now let you insert files from the cloud. While you can choose OneDrive, naturally, you can also add files from your cloud service of choice, such as Dropbox, as long as you have the service's app installed on your device. It's now easier to organize pages, as OneNote now lets you move and reorder pages in a given section.
You can download OneNote for iPhone for free from the App Store right now.
