if that app needs the intenet then yes
No
Yes it does require data.
Yea at least on my iPod most apps don't use data indent know if it's different for an iPhone though
Use the same iTunes account on both computers. If not, you can use home sharing when connected to the same WiFi network to transfer the apps and data.
no you cannot use ipod and iphone apps on itunes, but you can buy the apps on itunes and put them on your ipod and iphone
No, only when you download apps. This is pertaining to the iPod touch (4th generation) and iPhone (3rd generation). -Kristi
Yes, you can use many of the same apps on both your iPad and iPhone. Just make sure the app supports both iOS and iPadOS, then download it from the App Store using the same Apple ID. Some apps will sync your data automatically through iCloud, while others may require you to sign in separately. Keep in mind that some apps are designed only for iPhone or only for iPad, so they may not be available on both devices.
No you can use apps on the ipod touch also
Yes, if the apps are free and you are able to use a wifi connection if they require internet connectivity
There are a few Apps for iPod classics (solitaire, etc), but these are the only ones you can use. You cannot use iOS apps, as your iPod doesn't run iOS, nor does it have a touch screen (which all Apps require, as it is the iPhone's only input method). Short answer, no.
definitely NO, and if you want a lot of cool free iphone apps, use iAppWorld.net
While the App Store offers a number of Blood Pressure Tracking apps, any that will take your BP require an additional device. I use the iHome BP cuff, it connects directly to my iPhone via Bluetooth, and automatically records my BP on my iPhone, and will share the data with the Health app.
