Less Than Zero 1.5
the author of this app says:
This application will let you time anything from cooking to sleeping.
Less Than Zero works even when it's turned off. There are different on-screen alarms that you can easily set. When the alarm goes off, a message will pop up. If you're using this for cooking, you could set the message to "check the peas," for instance.
It's a neat little application and a great timer.
