3. Sleep Time
If you don’t want to spend the money on the incredibly awesome Sleep by Motion X, this is a good free alternative. It tracks your sleep cycles and has a few soundscape options to relax you as you doze off. It also wakes you up at the optimal time in your sleep cycle so you wake up feeling ready for the morning instead of feeling like pulling the covers over your head and going back to sleep. You will be lacking all of the extras that come with the paid-for sleep app, but if you are only looking for the basics, this is definitely the one for you.
