There are digital hydrometers, but they cost thousands, and then there are pycnometers, but they require a very clean sample of liquid with no trub. Refractomters are useful for some things, but they have a lot of trouble with measurements once alcohol gets produced.
In short, there are alternatives, but it's a lot easier to learn to love the hydrometer. Good luck!
(Out of curiosity, what's giving you difficulty?)
