Last October, we posted about another iPhone app -- Weightbot -- written by Mark Jardine and Paul Haddad at Tapbots. Now the company has shipped their second app, an iPhone conversion calculator called Convertbot (iTunes link).
Like Weightbot, Convertbot is a classy-looking and extremely functional iPhone app. Every detail of the user interface shows obvious thought, resulting in an app that is easy to use and look at. As with Weightbot, Convertbot also features sound effects that provide an extra level of fun.
What can you convert with Convertbot? Temperature, time, volume, work, angles, area, currency, length, mass, power, pressure and speed. How do you do it? There's a rotating selector wheel on the Convertbot screen to choose the type of conversion (temperature, for example), and a button to select the units (degrees Fahrenheit, for instance). To enter the known unit, you tap the converter display to bring up a keypad for tapping in numbers. As you tap in the numbers, Convertbot is busily converting the units.
If you're an aspiring developer and want to see a well-designed app, or if you're an iPhone or iPod touch owner who just likes cool apps, check out this US$0.99 app. There are tons of conversion apps in the App Store, but Convertbot is just too nice to pass up.
