A good to-do list for iPhone AND iPad

So I just recently picked up an iPad mini, and have been using the default Reminders since then. However, UI-wise, it's just a terrible experience, and it really kind of makes me not keep up with my todo list (call me superficial but yea.....). So does anybody have any good universal todo lists on iOS? I really like Clear right now, but it's kind of disappointing to see it's iPhone only (anyone have tips for an iPad version in the making?). Any other suggestions out there?
