Visual people may appreciate this time-management app, Time Timer, which has a simple concept: Track the passage of time via a bright-colored disk ticking down the seconds, minutes, and hours. No more 3, 2, 1 countdown timers—instead, see time wind down via the disappearing disk. It essentially looks like a pie chart going from 100 percent to the last sliver.

In the workplace, Time Timer can help users manage tasks and run effective meetings, brainstorming sessions, and training breakouts. Users can adjust the timer disk for up to 99 hours, and you can display the Apple version of the app on TV monitors and interactive whiteboards via AirPlay, enabling everyone in the room to track the time.

The app has garnered a 4.6 rating out of 5 in the Apple App Store. It's also available in Google Play.
