Exactly what I want in a calc! – Calculator 3.0 Review

I’ve tried a bunch of calculators on my iPad. They were all cumbersome to use, had a poor GUI, or focused too much on features I don’t use while making those I do use a pain (thus cumbersome to use). Some of them didn’t even have an easy way to store a number in memory! I mostly use a calculator for quick dilution and cell counting calculations in the lab. So, Hingis like a handy exponential function are key (if I want graphing, regression analysis, or model making, I’ll use my friggin computer). For what I want in an iPad calculator, this one is perfect! It has a simple, elegant looking interface (closest one to the iPhone calculator I’ve seen), and is quick and easy to use, but also has plenty of powerful/diverse functionality for my purposes. I agree with others that it’d be worth paying for, but there’s something I find very appealing about an honor system-based option to leave “tips” (something from my strident open source free-/share-ware days, I guess). So, if you get this app, and you like it, then hit the ℹ️, leave a tip, and support good dev’s ?.
