Calc XT for iPad is in top 100 Paid App in US.
Thanks for your support, Calc XT is now ranked no.69 on US paid app overall and no.11 on productivity paid app.
Before that, we did a two days promotion period that freed Calc XT to all of our users. What we got is RANKED no.1 on US free app overall!! It is encouraging, and we will keep improving Calc XT to make it not just an ordinary calculator.
