Normally I would not discuss other software on a developer's forum, but I haven't had a stable WORemote experience in years. No judgement, Dataton; dancing around Apple's IOS development roadmap is a general nightmare.
We use Octopus almost exclusively now for all Watchout and related show control: http://noismada.com/
User guide here: http://octopusapp.net/
Requires you to have a mac in the mix, and adds another stage of programming, but we've found it to be thoroughly stable. While there is a built in webserver to serve control pages to any connected device on the network, we use Duet on the mac and hardwire the control iPad.
Cheers,
