I Use This App All The Time!

I have used several different websites for the same calculations while reading books and articles that reference historical costs and spending. This app is by far the easiest-to-use. I will point out that it lacks complexity necessary for understanding the shifts in some historical currencies if you are going way, far back. For that, there is your imagination and knowledge of the times--how much did a loaf of bread or a horse cost, for instance? But for quick fact checking, this is THE BEST!


Absolutely Terrific!

Works like a charm and couldn't be easier to use! Developer updates to the latest information right at the beginning of the new year, much to their credit. I have used a number of other inflation calculator apps, and this one tops them all in terms of ease of use, length of years covered, accuracy and keeping them up-to-date. I wholeheartedly endorse and recommend this app for anyone needing such a useful calculator as this!


Use this anytime you watch a period piece!

I use it every time I watch something that takes place during different decades, like "Back to the Future", or every time I watch the TV show, "I Love Lucy". Whenever they mention dollar amounts I always like to look up how much things were during that year, and boy it really makes you appreciate the value of a dollar! It's so easy and a lot of fun!
