Ad-Free Unit Converter

By William Jockusch

Open iTunes to buy and download apps.


That's right -- this is a free app, with no ads! Saves you bandwidth, battery life, and annoyance. This is possible because the app is supported by its passive app store links, tastefully hidden behind a key on the keyboard.

This is a simple and intuitive unit converter.

It is easy to use. Gets you the information you need with a minimum of fuss.

Units currently included are acceleration, angle, area, density, distance, energy, force (or weight), mass, power, pressure, speed, temperature, time, and volume.

All the conversion is done on a single screen . . . who needs more?

Any comments or suggestions, feel free to write me at, but without the xyz!

Customer Reviews


First, the idea of having a website for users to leave suggestions for your apps is great, but it's execution is self defeating. If I have to go to your site, write my name, type twice my email then go to my email for randomly generated password that will be sent tome, only to return to your website to try to log in...
Wait! What was that great auggestion I had??? Forget about it!
Where is my old faithful calculator, pencil and paper...

Fantastic and easy to use

This is a very easy to use app for the average Joe to an engineering level. I would like to see a favorites button added in to have a list of favorite conversions, a swap button for easy switching back and forth, and a few more units like a mega gram. Other than that it's my favorite converter on the market!

No kitchen conversions I could use

As a chef in the US and the UK I really need a gram/ounce converter. Grams to ounces is a pretty common conversion you encounter all over the world so why don't you offer that in your conversion wheel? I've downloaded two of your apps in the last 24 hours for the first time Mr Jokusch.. The first one, your dice app, doesn't even open so it's useless to me as well... Bummer. The only reason this got any stars from me is that it does appear to have working conversions.
