In general, I really like this app. The one thing that really bothers me is when you minimize the app after doing a calculation, and then bring the app back up to enter a new calculation, it doesn't automatically clear the previous calculation. It just adds the numbers that you're starting to type on the end of the previous calculation. It also annoys me when you press C to clear, the weird flash across the display.

Looks like a great app. Popup every other screen with delay x. It is very annoying while searching for features. There are so many features that are difficult to locate the most common. I couldn't find the converter i needed with all the ads. I would buy the add free version of this app if i was sure i could use it. But so many adds I couldn't effectively evaluate its utility.

One of the BEST & MOST USEFUL apps that I didn't even know I needed! I've always just used the calculator app that comes with my phone. I had no idea I was missing out!! The capabilities of this app far exceed my needs as it has the ability to calculate almost anything you could possibly think of (and then some). I love that I can set favorites for quick access and that I can customize each calculator to my specific needs. I highly recommend this calculator. Download it now. You won't regret it!
