I’m a big fan of your app and have relied on it for years— However, in one of your more recent updates you removed the option to view last calculations. Now I rely on screenshots of calculations to remember what I’ve calculated in the last. Please bring it back!
Recent update in unit converter shows feet and inches, which is super useful for measuring my body fat at the gym. I also love this app comes with Easter Eggs customizing colors by swipe up screen and slide palette.
I LOVE this app!!!! Favorite app of ALL TIME! I use this for serious accounting work, etc. I've been looking for a calculator app like this for my accounting work for a long time, and now I've finally found it! The only suggestion I have is to implement some kind of "clear all" feature to erase all calculation history, such as by swiping up on the history log with two fingers (in addition to the current swipe-to-erase-single-entry gesture). Keep up the great job!!!! =) Hunter
