The Smart Flow application was designed specifically to be used with an iPad Air or higher. There is no app available for Android tablets at this time.

You can certainly add patients and make changes to the Flowsheets using the Web version on your tablet instead of PC, but the main Whiteboard and Flowsheets are best viewed and used with an iPad. Also, you will not be able to use the electronic anesthetic sheet without an iPad.
