AMAZING calc app! As I'm recommending it, I am high. No. Wait. I mean, I highly reccomend it. Yeah. When the app says "All-In-One" this one actually means it. It's customizable letting you choose the theme, and what calculators and/or converters you want to be displayed when the app is opened. It even has cool bonus features like BMI calculations,  body fat percentage, or input your birthday and it will tell you how many years/weeks/months/ and days you've been suffering on earth. My favorite feature is the results are displayed in BOTH decimal and fraction notations. The adds are minimal and don't take away from the experience or usability of the app. Hats off to the devs of this app! #Im36,406DaysOld#
