Best way to learn some Estonian for a trip?

I plan to visit Estonia sometime in the future because I have ancestors from there, and i want to visit my ancestors village of Soome, which i imagine requires a good proficiency in Estonian to get around in a small village. So since that's a future plan, i figure it's best to start learning sooner. What's the best app or website i can use to learn the language? And would it be possible to try to learn Võro, since I'll be in that region? I imagine there's even less resources for that though
