There are dozens of to-do-list apps out there, but Any.do stands out for hitting the delicate balance between clean and robust so that it’s easy to set up lists organized the way you want without too much clutter.
The app lets you set up lists for “today,” “tomorrow,” “upcoming” and “someday” that you can see at a glance and collapse or expand as you wish.
You also can view your tasks by category — personal, work, etc. Any.do syncs signed-in users’ lists with an online account in the Chrome browser, or it can hook into a Facebook account. Free, for Android and iOS devices.
