Android AWS Manager
Another free Android app (currently in beta), Android AWS Manager provides an interface to the EC2, RDS and Route 53 AWS services. Though designed primarily for phones, it also works on tablets.
Android AWS Manager supports fewer AWS services than AWS Console does, and it delivers less functionality for the services it does support (it won't allow you to create instances on Amazon's EC2, for instance). On the other hand, unlike AWS Console, Android AWS Manager supports Elastic Load Balancing (ELB), and you can switch between AWS regions while you're logged in.
This program is also not password-protected on its own, so you should enable the native Android lock screen PIN, password, or pattern.
