    I love this top-notch scientific calculator that I prefer to use. Could you please make some of the premium features available for free? For instance, offering 10 to 5 minutes of ad-free usage as a premium feature. I gave it a 5-star rating overall!

    Dealing with complex numbers and matrices is easy here. The best part is you can simply copy and paste. Plus, there's a user manual included that helps you with tasks like converting from a+bi to (r, theta) format.

    The calculator app has a cool design and features. I was thinking of buying the paid version, but there is one issue that is a deal breaker for me. Whenever I close the app, it always clears itself, even if I have checked the "Clear Screen" option in settings. I prefer a calculator where the history remains on the screen like an actual graphing calculator.

    I tried out this app and it's amazing! It works even better than the Casio 82fxZA. I tested it with some everyday high school math problems, and its memory is really good. I think students should definitely use it.

    I really like this app - it's so easy to use and looks just like a regular scientific calculator. However, I'm having trouble figuring out how to delete a digit. I can't find the key to erase a number, and I don't know where the (^) key is located! This digital calculator is fantastic! I noticed you can switch keyboards, but saw that it costs money. Regardless, I would definitely recommend it.

    I really like using this calculator as an engineering student. The ads are small and not bothersome. I appreciate that it's free and easy to use! One improvement could be adding a setting to disable automatic scrolling. When using a stylus, hovering over the calculation causes it to scroll up or down, which can be annoying. Whenever I try to edit the equation or move the cursor, it scrolls up before I can do what I need to do. Nevertheless, it's a fantastic app. Sending lots of love to the development team! ❤️

    I love this calculator app! It's amazing and you can even program it. Big kudos to the developers for creating such a fantastic tool. I wish they sold a physical version so I could buy it immediately. Trust me, it's perfect for all math tasks. Give it a try and see for yourself. Thanks to the team behind this awesome app!

    As a math teacher, I recommend this app for high school math. It lets you see the entire equation as you type and has an "answer" button for quick calculations. It's free with ads, but supporting developers is good. A feature request: having a lock screen option for tests would be helpful.
