BEST THERE IS, HANDS DOWN, PERIOD!!! Best calc of its kind! Better than "Office Calc"! Worth twice the price he's asking for it! Buttons are easy to see, the "Multiple Calcs Tape" is awesome and the tape lets you add notes to it and lets you email calcs with your notes added to whomever you wish! This is one cool calc, as is the Dev! Responsive and truly supports the product! Happy to be a customer and will definitely buy more of his products and will keep him on my very short list of "Top Quality Developers"! Seriously!
Tape Calculator Excellent app for when I have to track and review many steps or sub-calculations leading to my answer. I also really like the ability to email the whole "tape" to myself or others.
++good Tried most of the tape calculators available on Android, this is my choice for best-in-class. I do my taxes on it!
Superb App & Tech Support This developer has skills, in addition to responding quickly. I hope this team brings out more apps.
Excellent App is better than my default calculator app with lots of calculation option. Quite good for me since i always need to do complex calculations.
Perfect calculator. Ui can be improved
