Need to brush up on your cooking skills, but only have your iPhone close at hand? Don't panic: Google has quietly brought its Helpouts service to iOS. Much like the existing Android software, the iPhone-sized app (sorry, no iPad version) lets you schedule video chats with experts on topics ranging from baking to bike repair. Just be prepared to limit yourself to free advice -- Google isn't offering paid Helpouts in the iOS app. You'll also need to go to the web if you want to create listings for your own instructional sessions. If neither of those limitations is a deal-breaker, though, you can start taking lessons today.
