Waterlogged- FREE, iTunes: A man created this app for his wife who was in the hospital. You set a goal for how much water you want to drink, and track how many ounces you drink daily. It gives you the option to set reminders as well
Sleep Cycle- $1.99 iTunes: Sleep Cycle tracks you sleep progress, and has an alarm to wake you when your sleep cycle is coming to an end, supposedly giving you an easier wake-up. Due to the fact that I am most definitely NOT a morning person, I was skeptical. It worked- but not in a magical,"Wow, I'm so happy about this! I can function like a human in the morning!". If you want to save money, there are similar apps like Sleep Cycle for zero dollars and zero cents.
Hope you all enjoyed this! xoxo
