Meeting Cost Meter is a beautiful app that lets you easily see how much a meeting costs. Use it to improve your teams efficiency. Or use it just for your own curiosity.
The clean design makes it really easy to use. You can display the animated meters during a meeting or, since you can enter any start and end times, use it to calculate costs for any activity whether it already happened or is in the future.
Note: none of the information you enter in this app is sent to the Internet. It is all kept local on your iPhone or iPad.
