They have “fast track” contests that run for 24 hours so if you need a logo designed for you app, there is plenty of time. Just sign up and launch your contest. You will have to pay the fast track upgrade and your prize amount ($100 for logos), however 99Designs has kindly offered to refund the fast track contest upgrade fee ($54). Simply email them with your 99Designs user id after your contest finishes.
