iPhone App – Units

I had seen this application in the AppStore before we left for London but for whatever reason I didn’t think it would be needed or all that useful. I installed it a couple of days after getting here and have used it a lot.

If you find yourself needing to convert from one thing to another a lot Units is the application for you. Currencies, lengths, speeds, etc. — it does them all.

That isn’t enough magic to get me really excited about an application. What I like so much is how fast it is to use. It uses a calculator interface to make it super simple to get a conversion done. I had an initial complaint with how long it took to find the right mode, but they fixed this with a user-interface change in the newest release as well as some additional conversions.

Anyway, another great example of a very handy mobile application that adds significant value easily.


  1. Jamie, just curious why wouldn’t you just use google conversion ?

  2. Senthil, the UI is much, much faster than doing a Google conversion. Plus, very importantly, Google is online so there is roaming data costs and huge waits added.

    Pretty much all speed…

  3. cool … how does it update the currency conversion rates?

  4. It downloads updated conversion rates once a day. Close enough for tourist work.

  5. psi 2 Bar conversion is not correct

  6. Why is Indian Rupee not part of Currency unit?????
    India is one of the fastest growing economy in the world. It has currency of countries which are not heard in daily business routine.
