Works Flawlessly, Decided to Upgrade

After a few years of using this app, I needed to convert something this AM and as usual it just worked. I decided to buy the app to help support development and maintenance. This app has been my standby weather traveling abroad or working in the hospital. We take it for granted that these take money to develops and maintain, so I became a paying customer as of this morning. Plus the annoying adds, will no longer be distracting me. Yes, yes, I know advertising helps to pay, but figure at $3 I could afford to do my part to help ensure this app continues to deliver performance to the level I expect when I open it up on my iPad or phone. Thanks for a useful tool I use Dailey.

Highly recommended

What a wonderfully helpful app! I doubt I will find much use for the additional features, beyond the currency converter, that come with the paid version, but the no-more horror of languishing trapped between US, UK and decimal - has made my life worth living. And so, in appreciation of a developer who, like a few others, clearly enjoys his work and has a healthy interest in making some efforts so much easier to deal with, I join with those who have elected to go for the upgraded version.

Oh, and perhaps a wee suggestion: would it be possible to pair the 'from' and 'into' by clicking on one's selection from the list of choices?

One more: the Chinese techies are about to test a super computer expected to run at 100 petaFLOPS. What/how fast is a floppy peta in Mbs, beyond threatening to melt one's grey cells?

The above comes with thanks and best wishes.

This application does everything I needed

This is one of the best applications that I've ever used. It's able to convert just about everything to just about everything. If you are a health care provider, this handy app will save time and reduce the risk of errors. One of the best features is the currency conversion. When you open the currency conversion feature, it updates with the latest rates. I recommend this application without any reservation.
