Ratings and Reviews
Currency conversion is worthless
The program does not update exchange rates, it appears that conversion feature is years out of date.
The program does not have a significant number of prefixes/powers for each unit (i.e. milli centi deci deka kilo etc).
It would be nice to select the base unit like “gram” then select the precision.
Works great for me
I love this app. I've had it for over five years now (I think). Had a different one before but preferred this to it. I have to be clear though, I only ever use it for volume, distance, and weight and for these it works fantastically every time. Never crashes or gives me bad information.
I cannot recommend purchase of this app. I bought this app because I wanted to do on the fly currency conversions with my Apple Watch, and it was recommended highly in a Computerworld article entitled the top 23 Apple Watch apps you should get. However, when I tried it today in China, it was more than 10% off today’s USD-CNY exchange rate. I’m glad I didn’t make any decisions using that exchange rate today. Could have cost me big. With no real support, I had to delete it.
