After letting us know last month that it was getting ready to release a toolkit to let developers easily bring their Chrome web apps to iOS and Android, today Google released a developer preview of the tool. In its blog post, Google explains the tool is based on open-source framework Apache Cordova, which allows devs to build native apps for iOS and Android using CSS, HTML, and Javascript. It’s also making a lot of its own core Chrome APIs available to developers through the preview. It essentially means devs will be able to bring their Chrome web apps to the App Store and Google Play, but it will also let them build new cross platform apps in CSS, HTML, and Javascript. Google explained how it works: expand full story

Chrome on iOS reduces mobile data by up to half – but only for invited users

If you use Chrome on your iPhone or iPad, and you’re not running the latest version, you may want to update it. Google has started inviting selected users to enable the data-compression feature it first launched on Android back in March.

For an average web page, over 60% of the transferred bytes are images. The proxy optimizes and transcodes all images to the WebP format, which requires fewer bytes than other popular formats, such as JPEG and PNG. The proxy also performs intelligent compression and minification of HTML, JavaScript and CSS resources, which removes unnecessary whitespace, comments, and other metadata which are not essential to render the page. These optimizations, combined with mandatory gzip compression for all resources, can result in substantial bandwidth savings.

Or, in less technical terms, Chrome strips out everything not needed to display webpages properly, so you get the same experience but with up to 50% less data usage. For those who do a lot of browsing on 3G/4G, that can make a big difference to your monthly data bill.

So far, only a relatively small number of users appear to have been invited to participate, but that number is likely to grow over the next few weeks.

Interactive iPhone 5S with iOS7 concept based on recent leaks

Product comparison site Recombu has created an interactive iPhone 5S with iOS7 simulator, in large part based on our exclusive preview of what to expect.

9to5Mac has heard new details about the iOS 7 redesign from sources. According to the site, iOS 7 has been described internally as “black, white, and flat all over.” Skeumorphic elements have been dropped in favour of flatter and cleaner designs, with Ive apparently saying that physical metaphors “don’t stand the test of time.”

The simulation, based on a roundup in which most of the content will be familiar to 9to5Mac readers, allows you to switch on the phone, swipe to unlock and click on a number of the app icons to see non-functional mockups of what the new apps may look like …

When Apple launched the new iPad on Friday, it did so with a new dual-core A5x processor and quad-core graphics inside. During the product’s unveiling, Vice President of Worldwide Marketing Phil Schiller talked about the new chip noting that it provides four times the performance of Tegra 3. Nvidia was quick to question the slide displayed by Apple onstage (pictured right), which did not provide any specific benchmark data. We now finally have some solid benchmark tests courtesy of Laptop Mag that provide us new insight.

For the benchmark tests, Laptop Mag used an ASUS Eee Pad Transformer Prime, which is powered by Tegra 3, and put it up against the new iPad in GLBenchmark 2.1, Geekbench, and browsers’ benchmarks with Sunspider and Peacekeeper. In its last test (video above), the publication did a side-by-side subjective gaming performance test to try to spot any noticeable differences between the same title running on both devices. Here is what the publication found:

The first Ice Cream Sandwich handset, the Galaxy Nexus, hit the UK this week (US launch coming soon) and AnandTech has benchmarked the ICS/Galaxy Nexus combo vs. the iPhone 4S/iOS 5 combo.  The Galaxy Nexus processor/GPU isn’t groundbreaking by any means, but the new software inside is certainly packing a punch beating iOS in a few key areas. As seen in the graph to the right, the Galaxy Nexus has a slightly faster tested browser than the iPhone 4S — a crucial day-to-day necessity for users.

The Galaxy Nexus also comes up with the win in JavaScript loading, bringing faster load times than the Droid RAZR and iPhone 4S. Don’t think the Galaxy Nexus is going to come away with everything, however. Both Apple’s iPhone 4S and iPad 2 outperform the Galaxy Nexus in GPU loading — which is limited by its slower SGX 540 underneath.  That’s an important consideration for gaming.

The Galaxy Nexus’s hardware has been dubbed very smooth compared to older versions of Android. Google is activating 550,000 Android devices a day and is still behind iOS in total Activations at 200 million total.   Head after the break for more graphs.
