Nifty Box remains free. Discontinued, but free...
and for 25$, I prefere give a little more and buy Leap and/or Yep or even the promotional pack from the Ironic software (51,73€ = 4 apps).

A different app but also an organizer, Yojimbo. Is a bit expensive but it's a hell of a app (I also have to try Together).
