iCuppa

From the App Store description:

Cuppa for iPhone is finally here! iCuppa is a small application for iPhone and iPod touch to time your cup of tea as it steeps. Tired of leaving your tea too long, to become bitter and cold, or drinking it too soon and not appreciating its full potential? Then this utility is for you!

Just tap the name of the beverage you are brewing. Cuppa will begin timing the brew, and you’ll see a teabag appear in the cup and gradually darken as the tea steeps. A countdown timer shows the steep time remaining. When the tea is done iCuppa will let you know by making a sound.

Tap the “Edit” button on the selection screen to customize your personal iCuppa beverage list and steeping times.
