While there isn't a fully optimized version for the iPad, you can still install the iPhone app on your iPad. Besides possible display issues, the only limitation is that you won't be able to measure your heart rate using the camera.
要在 iPad 上安装 Withings App 应用,只需在 App Store 中搜索“Withings App”。显示搜索结果后,务必选择应用左上角的“仅限 iPhone”而非“仅限 iPad”。然后即可安装 iPhone 版应用。
