Uncover the ways takaaki024 (the company) bills you and cancel your Reorder Contacts subscription.
Note before cancelling:
1. Note: Reordering is disabled by default for non-iCloud contacts (e.g. Google Contacts), as it may not work correctly.
2. I don't know why standard "Contacts.app" or other AddressBook Apps on App Store don't have this feature.
3. Reorder It! is an iPhone App which helps you reorder the addresses.
4. It's useful when contact has multiple e-mail address.
5. You can enable it in Settings.
