Hi, I would like to tell you try the app which provides you a new unit converting experience. Convert Sense provide a new unit converting experience, common units belongs to different unit system are listed (mixed category) together, user just need tap unit, input and done. The second view is featured with searching and indexing to setup convert. All available target units are listed after you tap on the source unit. This not only provides the result but related unit knowledge. The third view will learn user habit; the list uses a unique way to rank the converting history. http://itunes.apple.com/app/id423507227?mt=8 Thanks. vThinking Studio
