I like the option to double the size of iPhone apps on the iPad, but I think the real strength of the device is the fact that it will have its own applications specifically developed for the iPad. The developers of 1Password have announced they are working on an iPad version of the popular password manager application.
The application allows you to manage your passwords and make it easier to log in on websites. There are already 2 iPhone apps of 1Password and there’s also a desktop version. It is possible to sync via Wi-Fi so you can keep your data up-to-date on both your desktop and your mobile phone.
The iPad version of 1Password has a new interface with a long toolbar. There’s also more space to show information on a single page. Although the pictures are still mock-ups, they still show the power of a larger screen. There will be more information on Switcher’s Blog later as the developers are working on the application.
