I've reviewed this before and always given it 5 stars. I have knocked it down one star this time. Here is why. I understand the need to support the free version with ads. As someone whose income is going to be reduced considerably soon due to a voluntary career change, I'm not in a position to pay for apps at this time. The ads were fine before, but now they are too close to frequently-used keys when I am in landscape mode. Please move or shorten the ads. Functionally, you have a great product, but I can't deal with constantly hitting the ad instead of the intended key and then getting taken away from my calculation.
There are many mistakes and bugs; when I rotate the display the scientific calculator won't appear and I have to restart the app to achieve it, Parentheses when all closed it refuses to calculate and says that they aren't closed, Graphs sometimes are inaccurate: 1/x won't be displayed but 1/(x+1) will, There are also bugs when typing parentheses powers and fractions. I hope they will be fixed as soon as possible Thanks...
Have used this app for a couple of years now and continue to enjoy its functionality and ease of use. On top of that it looks good too.
Excellent app. Easy to use. Exactly what most people need.
