The web app is currently 111mb and is hosted by Dropbox so there could be things that go wrong. Dropbox is meant for sharing, not for hosting a web app like a server, and bandwidth seems to be limited. Because of this we prepared for the PoL by wrapping it into an app using Web View in Xcode as well as within an iBook as a widget. This will eliminate internet based issues as all the files would be stored locally. However, there seems to be a delay for the sounds so it is for a last resort. If all fails, then Hype Reflect can be used as it works very well and has no audio delay like the other options.
