Design and usability issues driving negative reviews.
Users trying to input simple values are interrupted by dialog boxes asking for additional inputs they don't want to provide
"I wanted to hit the same keystrokes on this calculator as I do on my real calculator. That doesn't work. It keeps open up dialog boxes that have more questions than the single input I was looking to put in."
The app switches decimal points and commas in number display, causing confusion and incorrect inputs
"I am using three decimal places. No matter what, the comma and the decimal places are switched. For example, if I type in 2,495.16, it actually displays 2.495,16. Every single number is like this. Even 2+3=5,000."
Key calculator functions that users expect are either missing entirely or difficult to locate in the interface
"First problem and it doesn't calculate. Watched video and interesting enough the tab to use wasn't present."
The app doesn't properly adapt to iPad screen sizes, resulting in stretched and truncated display
"Also the app stretches in slide out mode on iPad Pro making for a ridiculously stretched and truncated ux."
