Recommend voice recorder app to replace native "voice memo" app missing from iPad?

Hi,

Can anyone recommend a simply, easy to use voice recording app that I can use on my iPad since Apple refuses to include the native "voice memo" app on the iPads? I just need something simple and easy to use that records without any limits, prefer free but willing to pay a small price for something that works right.

Also while I'm at it...what about a calculator app as well? I can't believe they remove all of these native apps for the iPad, what the heck are they thinking?

Thanks!
