In iOS 4.3, Apple has supposedly limited the speed of web apps added to the iPhone’s home screen. Develepors and users have been reporting that web-based applications launched from an independent springboard icon are loading more than 2x slower than sites opened in Mobile Safari.

Meaning that, web apps/favorite sites launched from an icon shortcut aren’t given any access to the Nitro Javascript engine that’s baked into iOS 4.3. If Apple has intentionally hampered the performance of web apps in 4.3, such a move could been seen as a subliminal push to get people downloading more App Store apps.

If you’ve noticed lagging performance with your favorite web apps in iOS 4.3, there’s an easy way to take advantage of Mobile Safari’s full resources…

While it’s not technically a solution, opening web applications in the Mobile Safari app will bypass any limitations placed on sites launched through icon shortcuts. Lifehacker points out that launching web apps once Safari is already open helps the site load faster and store data offline more efficiently.

This news is particularly sad for iDB because we have a web app with an icon that looks great on the iPhone’s home screen. If you add as a springboard shortcut, you’ll get an easy-access portal to our web app.

For the time being, you can make a new bookmark folder in Mobile Safari with links to all of your favorite web apps. Opening sites directly in Mobile Safari should fix any speed problems.

If you haven’t noticed a problem with web apps on your home screen, don’t worry about trying to fix what isn’t broken. Not everyone is reporting performance issues.

It’s highly doubtful that Apple is purposefully limiting resources for shortcut-saved web apps in iOS 4.3, and chances are it’s just a bug that will be fixed in a future update. It would be a saucy story if Apple was in fact hindering apps that didn’t come directly from the App Store.

Have you noticed slower performance from web apps in iOS 4.3? What about the iDB app? Do us a favor and compare the performance of our site through our shortcut and Mobile Safari.

    So the title is “how to speed up web apps” and your solution is don’t use them? Really? I expect more from iDB than this…

    • That’s not the solution. It’s to launch them from a different place until Apple patches the bug (and only then if you actually have the problem). Not one place in the article did I say to not use them.

        Dont listen to that moron, i bet hes the type of user that goes in the app store doing one star reviews and putting “sucks” in the content all day long

    Sheesh, this blog really has a harsh user enviroment.

    Someone comes in and hates on this and that, and then everybody is hating on him.
    I don’t know, maybe I’m just used to swedish courtesy. This is one of the few foreign sites I visit every day, so I have little to compare with.

      Sorry, I meant environment. I’m swedish, my english isn’t all that good.

    since the upgrade I have noticed the app store is slower. when you open it to check for updates, I get the number of updates badge first and then the page flickers and then loads up the list. I guess it is a proper app, but is working like a webapp. is it related?
