  1. 5/5Best iPhone calculator app !

    Wow this app is amazing.. great for history of calculations.. sharing calculations.. and also converts units of measurements pretty easy.. speaking of converting units of measurement.. you should check out Converter app from this same developer ⭐️⭐️⭐️⭐️⭐️

  2. 5/5Great RPN calculator

    I was looking specifically for a RPN calculator that also has unit conversions. I use these functions daily. I downloaded and tried many calculators but something was always not right with them. Then I found this app, it works great! Absolutely the best I have used. And to make it even better there was a small annoyance I contacted the developer about. He agreed to fix it and the fix was in the next release. Just wow! Thanks for making this app available.

  3. 5/5AIO rocks

    This calculator truly is a one stop shop for all my calculating needs. Though it offers so many complex functions, the interface is user friendly and easy to work with. I especially love that I can record my answers for later use. 2020 was a crappy year so it’s great to have a straight forward high functioning reliable calculator.

  4. 5/5Copy and paste don’t work

    I tap the answer area and it gives a “copied from Google” message, but the number stays “0”. If it’s more complicated than that, I can’t find documentation that says so. Edit: Thanks Ramon. Double-tap works great.

  5. 1/5Annoying to use

    On my iPad Pro this app ‘blinks’ every time I enter a number and two taps of the enter key are required to put a number in the stack. Most of the time the keypad is unresponsive to entering numbers (as opposed to the immediate and positive keystrokes with which I am typing this review). Lastly, trying to enter an exponent, such as 10 E-6 using the y^x function yields 0.
