Best Swim App for Andriod

What is is the best swim app for Android? I have Record My Swim, but it didn't let me put in my weight or height and I am suspecting it is not very accurate. (Added to that if I swim faster my calories are lower...not sure how that is possible when I am putting in more effort.)

Is there a better app? Tell me your iPad ones too so that can see if they have an Android version.
