Touch targets are too small – Amount - Unit Converter Review

Specifically the top left and right buttons used for back, cancel, settings, search, etc..... on iPhone XS Max and I have to prod multiple times in those upper corners until I finally get the pixel required to tap the button. Also, could we please get numerical systems as a category? Converting to binary or hexadecimal would be useful.
