1) This is for viewing your pool only. At this time we do not have any administrative features built into it. That will come as we build it out.
2) Depending upon the screen resolution you will see different stats columns. If you are on a smaller phone you will only see a couple basic columns of data. If you're on a tablet you'll see more, etc. We have designed it to work on Apple and Android.
It's in BETA mode right now so we don't expect it to be perfect yet, but we're happy to get feedback, so contact firstname.lastname@example.org if you have some.
