Timeful - Another scheduling app, only this one "gets to know you"
This is an iOS app for now...I wish there was an android version so I can try it out! Timeful allows you to schedule your life easily by syncing your calender, to-do list, and life goals, such as exercising.
As of now, google calendar has been enough to keep me on track...but maybe an app like this would be beneficial!
If you're an iPhone user, then check out the app at https://itunes.apple.com/app/id842906460
