Timeful is a task-management app that intelligently helps you find time to do the things you want to do, without overriding the things you have to do.
Part calendar, part to-do list, it syncs with the calendar on your phone, so it can learn your schedule. It selects daily and weekly tasks that you want to complete, as well as “good habits” such as exercise, catching up on email or calling friends/family, and finds free time in your schedule so you can get these items done.
It also learns your behaviour over time, so the more it’s used the smarter it gets at making recommendations.
Free for iOS; Android version coming soon.
