What users are saying:

• I use iota-calc pretty much on a daily basis to plan out calculations for programming tasks I have. I also use it when helping my son with his homework. -- Steve Mayer
• Very, very useful little app, well worth the money the author is asking for! -- ScottM review of Mac OS X version on MacUpdate.com
• This is a very nice and unique calc, and they are steadily improving it. I'm giving it a five for current usability, improvements, and a GREAT price. Get it now, before demand drives up the cost. -- MikeyK review of Mac OS 8/9 version on VersionTracker.com
