J.D. Power MarketValues can be used on iPads, but requires iOS 11 or higher. iPad 2 (discontinued 2014) can only run iOS 9, so MarketValues will not work on an iPad 2.
The exact supported device info is:
- iOS: Minimum of iOS 11, which supports iPhone 5S, 6, 6 Plus, 6S, 6S Plus, SE, 7, 7 Plus, 8, 8 Plus and iPhone X.
- MarketValues also supports: 6th-gen iPod Touch, iPad Air, Air 2, 5th-gen iPad, iPad Mini 2-4.
- Android: Any device running Android API 19 / OS 4.4 (KitKat) and above
