The $9 app from is useful for travelers or for those who want to keep a record of personal data. The interface is a bit crude, and it's debatable whether you should rely on one tool for all of this personal info. Still, helps you stay organized, and it's a useful tool that works reliably well.

The main point of My Eyes Only is to help you store all of your personal ID and credit card data on your phone. (It's worth noting that My Eyes Only shares many features with ( Macworld rated 3.5 out of 5 mice ), a mobile secret keeper that works in tandem with the desktop app of the same name.) This is helpful when you need to fill out forms, buy something on the Web, or just as a back-up. Still, in many situations--shopping at a brick-and-mortar store or boarding an international flight--you can't just give a number; you need the card or document itself.

It's easy to enter data into My Eyes Only, with the app displaying a visual representation of the actual card or document--such as a Bank of America card or a social security card. You can add membership info for your health club, and bank accounts (with the routing number and bank number used for direct deposits), but you can't create your own category or design your own templates. There is a generic other category for adding other kinds of data, such as the IP address for your home router.

You can also store login info, such as your username and password. As the Web moves to authentication methods such as OAuth and OpenID, where you type your Facebook username and password to gain entry into a different site, the login storage feature becomes less appealing.

My Eyes Only works with the desktop , which costs $10, to back-up your My Eyes Only data over the Internet. The back-up service, and the app itself, worked well and never caused any crashes or--perish the thought--loss of data.
