There is no direct way of transferring any apps from your iPhone to an Android device, you’ll have to download all of it again. Also take note that except for really popular apps, you might not be able to find an Android equivalent of the same app at the Play Store, Google’s own app store, but Android does have widgets.
An Android widget is placed on the home screen and works hand in hand with apps installed on the device. It allows quick access to things you can do on an app such as faster browsing through emails straight on the home screen, without needing to open the email app.
You can access the Google Play website from your desktop browser to install apps onto your device. Using the same Google Account used during the setup of your Android device, Google can detect your device and remotely install apps onto your device. Just click on Install.
