I know that this is probably one that gets asked often, but I'm hoping something may have changed recently.
I'm getting a feel for Web AppBuilder - it seems ideal for nearly everything we need it to do, except for one thing - taking maps offline.
Currently we use Collector around our organisation, which is quite good for this. It's also quite necessary, as a lot of our work is done where there is no signal whatsoever, and I was hoping that a widget was available (or some other methodology) to allow us to select areas, just as in Collector, take them offline so they can be used out of signal range, and then sync them up again later.
