Smartphones offer apps to map everything from pregnancy weeks, to contractions, to medical records. If you don't want to spend on fancy features you will rarely use, simple countdown apps are a free and efficient way to keep track of time — whether you're marking days until the stork is supposed to land, your next moms' night out, or the new year.
