Twin-Calc

This is a very useful app. The only thing missing is the ability to use it without turning my phone. Please add support for portrait orientation.

The idea seems simple of having two calculators, but the result of how they work together is superior. The ability to calculate two things side by side is helpful when comparing prices, performing complex conversions, validating finances, etc. Wonderful idea, pure genius!

What a novel concept. On the surface it seems redundant but after considering how often we use math and I find myself pulling up the calculator I realized just how amazingly efficient this calculator layout is. Simply a brilliant idea turned into a wonderfully useful app that will save me a ton of time in day to day life!
