Apple’s Keynote for OSX and iOS provides a great and intuitive alternative to the staple Microsoft Powerpoint.
The OSX and iOS versions are now closer aligned so that “handoff” editing is easier between all devices with presentations being saved in the cloud.
Keynote Remote is included in the latest versions of Keynote for iOS. To use Keynote Remote, you need an iOS device with Keynote 2.1 or later and a Mac with Keynote 6.1 or later.

I have made many presentations to my Clients using the Keynote app and my iPad Pro and it worked seamlessly.
