Another great iOS App: iSafeBox is now available on App Store. iSafeBox provides most secure protection for documents, photos, passwords and personal information on iPad/iPhone using AES 256 encryption. From now on, a user will never need to worry about his/her critical data on the iOS devices if they are lost. Without knowing the master password, nobody will be able to decrypt the data stored in iSafeBox.
iSafeBox also provide Sync Service to users, which allows data backup and restore in iCloud. The Sync Service costs $2.99 and it also removes the ads.
