Convertbot Overview

Convertbot is an amazingly smart unit conversion robot for your iPhone and iPod touch. Convert between over 500 units across over 20 categories including currency, time, length, and many more. It’s even smart enough to convert between mixed units like Foot + Inches, Pounds + Ounces, Minutes + Seconds, and more! Converting units has never been more fun.

Not your Average [Boring] Utility

Converting units is a chore, but it doesn’t have to be. Convertbot is here to change that. It’s unique interface, beautiful animation and sounds will dazzle and delight with every conversion. But don’t let that fool you into thinking it’s just a toy. Wrapped inside this joyful experience is a very powerful and capable unit converter. Read on to see why.

Packed with a Punch

Convertbot contains over 500 units spanning over 20 different categories. Yes, you read that right. Fumbling your way through 500 units sounds like a chore, right? Not with Convertbot. You can enable only the units you want to use for a completely customized converter. With our beautifully categorized views and search tools, you’ll be able to find what you need quickly as well.

Mix it Up

Ever wanted to convert to and from Feet + Inches? Or maybe Pounds + Ounces? Most unit conversion apps aren’t smart enough to understand mixed units. If you are 5ft 9inches tall, you have to convert that in your head to Feet or Inches before another unit converter can understand it. Convertbot is smart enough to understand many popular mixed units like Foot + Inches, Pounds + Ounces, Stones + Pounds, Minutes + Seconds, and many more.

Let Convertbot do the Math

No need to do the math in your head anymore before converting a unit. Just enable the calculator in Convertbot and perform basic calculations to get the converted unit result on the fly. You can even tell Convertbot how many decimal places to show before rounding.

On the Money

With over 150 different currency units, you’ll have no problem trading with almost anyone around the world. Currency rates are automatically updated every time you launch the app with the option to turn off the auto-update to save on bandwidth costs.
