I agree wholeheartedly! There may be more sophisticated calc apps out there but why not combine functionality with elegance? It appears to be working for the 'other guys'. At the risk of blasphemy, "Good Job(s)". [BTW, how about a black skin?]

An excellent calculator - does what it says on the tin. No bloatware, all a well designed application should be - visually appealing and intuitive. And its free!

There is a new update. Now the program is working fine on my storage card, too.

Program works fine when using the internal memory. When you go to the website's forum, you find the white screen hangup mentioned is a result of loading to external memory. A link is provided there to a beta version that installed and operated fine. The developer mentioned that a new version will be out within a week or so that will have the ability to run on external memory.

Sucks. Freezes my MDA.
