Viewing and using Articulate Rise courses OFFLINE on Samsung Android Tablets

Hi everyone, we just spent months developing a presentation in Rise that will be used by field staff delivering the presentation to customers. This must be done offline as internet access is often spotty They will be using laptops and ipads. Please share the best possible way to do this. I am aware of the publish to web>download zip>extract>navigate to index>click method that works on a PC... what about easier ways and using an ipad? Thanks!
