It depends on the app. Some charge, some don't.
Updates offered through the App Store on the Update screen are always free. There may be upgrades and additional features in apps available for an extra charge. This will always be clearly spelled out to you as an in-app purchase.
No, you do not. Everything will remain the same when you update your iPod when it comes to apps.
No, they will not charge you for apps if you don't opt in to buy them.
Yes. It's also free to update payed apps, that you already bought.
First you go to your app store. Next click on the tab "updates" under all apps. Then it'll show all your updateable apps. Choose 1 and hit "update", it'll ask you for your password. To update all those apps hit "update all" then type in your password. Hope this helps!
mmm go to my documents/music/itunes/mobile applications delete the apps directly from that folder to prevent them from syncing back to your device
On the App Store where you gets your apps from hoped it helped
No, but in appstore you can just click update all, and it will do it for you.
To update games on the Amazon Appstore, open the app on your device and go to the "My Apps & Games" section. Here, you'll see a list of installed apps with available updates. Tap the “Update” button next to the game you want to update, or select "Update All" to update all apps at once. Ensure your device is connected to the internet for the updates to download and install.
Yes I believe they are free
It means that you need to update either your software or apps depending on what the message is asking you to update.
Open up your Library to the Apps tab then hit Check for Updates.
