Top Free App2SD Apps for Android Devices

Here are the top app2sd apps to move your apps from the internal memory of your smartphone to your SD memory card.

AppMgr III (App 2 SD)

AppMgr III is one of the best App2SD android apps for moving apps from internal memory to your SD card. It is also known as App 2 SD and it supports most of the android smartphones and tablets. Upon installing it scans your android device for all the apps present on your phone memory, SD card and movable to SD card. It also shows you the total and available SD card and Phone memory. The sort functionality lets you to sort apps on the basis of total size, data size, cache size, application size, application name and last update time.

AppMgr III (App 2 SD)

On the Movable tab you can move the apps from phone memory to the SD card and on the SD card tab you can move the apps from SD card to phone’s internal memory. The Phone only tab shows the apps that cannot be moved and will stay only in the internal memory unless you Root your android phone. This app2sd app also lets you clear cache so that you can get more free space on your phone memory or SD card. There is a search feature to search the apps if your apps listing is very long. You can also move all apps at once and hide apps you like. The Freeze apps feature lets you freeze apps so that won’t use your CPU, memory or other resources. From its interface you can also uninstall apps in batch or share apps with your friends. This App2SD app does not require ROOT. Highly Recommended App by me.

Note: This App2SD App may not work on HUAWEI, LG, XIAOMI, ASUS with Android 6+ because the manufacturers in these devices have removed the app2sd function.
