There is an application for iPhone called Tea Time, which measures who long your cup should be brewing for. You get to choose between black, green, white, oolong and herbal tea and whether you are using loose leaf tea or bagged. You can also choose tea strength. Basically you have all the same options as in the Zarafina Tea Maker, except for that you will have to handle the water-cooking and all other manual actions yourself. This application also suggests water temperature and is capable of remembering the settings of your last brewing. It has a decent look and it’s only $1, so I guess you won’t be loosing a fortune and it might help you with your tea.
