As of right now, Yahoo Finance has the same watchlist functionality, but with more data than Google Finance including options and crypto and much more powerful charting and native mobile apps. You can even link your real brokerage account for real-time portfolio tracking and trading directly from their apps and site.

(If I sound like a shill, I work for https://trade.it which provides broker API functionality to Yahoo Finance, but I have also been trading and using Yahoo Finance for over a decade, way before I ever became technologically involved with them)
