Nice calculator, but very slow loading time – Calculator X Pro: Metric, Currency and Unit Converter Review

Every time I use this calculator app I am usually in need of getting a calculation done quickly. With numbers in my head I want to quickly put them into this calculator app before I forget, but the app load time is so slow. Is there a possibility of getting the app to load quicker? By the way I'm using an iPad 4, which should have more than enough power to open this app quickly.
