I have it, but frankly haven't opened it in months. I use Sportacular (Yahoo) regularly and it's all I need - and they've improved it immensely recently with some nice updates.
I deleted ESPN off my iPad, all the latest version does is crash, even after a delete/reinstall. The iPhone version only crashes about 1 every 5 or six times I launch it....still bad.
I don't see any ads. It has never, however, crashed on me. Have you tried the app yourself? EDIT: small ad at bottom screen. So small I never noticed it.
