Ratings and reviews

Best multi function calculator I have found. I mostly use the basic function, discount, percentage, tip & change measurements, (ex: meter to inches.) The app also allows you to choose which functions you want showing, so you don't need to see what you won't use on a daily basis. However, you can always get back to settings if your need arises to use those hidden functions.

Clear and accurate display. Easy to use. Six months later it's working just as well. Never crashes or malfunctions or interferes with phone. Accurate calculations. Color combination has a professional look. A keeper. December 2022, and I'm still a regular user. Good job! 🙂👍👏. Updated review on 2/18/23 - This app works great each time. It's appearance is clear and easy to navigate. Excellent job! 👏👍💯

Does what a good calculator should do. The display is clear and logical. I have used it for conversion for both units and currency. I used it recently to calculate our estimated fuel costs for a road trip vacation. It even brought me back to working with hexadecimal. I can't believe we had to do that manually. Overall, it's a great app to have on my phone. I just noticed that I can change the color.
