Launch the Axis app on your iPhone or iPad, and you get complete access to any bookmarks you set back in your browser, along with the same integrated search options that the extension offers. And Axis keeps track of the sites you visit on your iOS devices (if you opt in to allow it to do so), so when you're back at your desktop again, you can quickly revisit the sites you last browsed on each device.

In my early testing, Axis is certainly interesting. If you regularly surf on multiple devices and either iCloud sync isn't cutting it for you, or you want full access to pages you've visited from iOS--not just the ones you've bookmarked--the free Axis service is certainly worth a look.

That said, I found that sometimes the browser extension's search field stole keyboard focus when I visited certain webpages. Other times, I forgot to use the integrated search box, falling back on my browser's integrated search bar instead.

Still, Axis is an ambitious, well-implemented offering from Yahoo. You can install the extensions from once that site goes live later on Wednesday and grab the app .
