Ratings and reviews

Update: Amended review to 5 stars following developer fix. It's simple and useful with lots of things you didn't even know you might want to convert! I upgraded to the paid version. However the reason for only three stars is useability. The app fills the whole screen so the top and bottom are covered by the phone's control buttons and top info bar and therefore you can't click on those areas. I tried to use the 'send feedback' feature to report it with a screenshot and it doesn't do anything.

I bought the pro version. Some of the categories work fine, but I found at least one that has a bug in it. I ran into a problem when I went into convert decimal to fractions category. Every time I hit the decimal point, it either kicks me out of the app completely, but at the minimum, it kicks me out of the category.

It works just fine for everything except what I needed it for. I needed a quick decimal - fraction tool. When fabricating with steel and aluminum l found some material is metric , or just not SAE. So I needed a quick way to dec-fraction and vice-versa. This tool is premium so I had to purchase subscription and give it a try- total disappointment. Every time I try to enter a digit the app closes . I've tried 50 times and exactly the same results. All other conversations work
