I love the custom tool feature very much and have used it to build several routine calculations. The currency converter is also very useful, and it seems to be able to keep up with recent exchange rates. 👍

The pop-up calculator was the main reason why I used this calculator, but it hasn't worked in months. The rest of the calculator is great, but I'm really frustrated that this hasn't been fixed
