Know any good behind the dm screen apps? I've been using pen and paper for a long time but, I'm trying to find a good app on tablet or phone for running initiative, timers, inputting (or preferably looking up and inputting) monsters and npc's. I've found 1 or 2 that can do some stuff but, I thought I'd ask around before going hard and manually inputting 3 monster manuals worth of content into an app.

As for story and such I'll probably stick to my notebook for that, ya know 1 step at a time.
