Reverso App has been absolutely the #1 tool I use to learn Spanish. I've used it for about 2 years, and I can't imagine living without it, now! I read news articles in Spanish, and Reverso is there to show me what any word or phrase means in a heartbeat. I watch movies and TV in Spanish on Netflix, and Reverso is right there to show me what any word or phrase means -- all i have to do is click it! On top of the translation and definitions, Reverso has hundreds to thousands of example sentences for most words and phrases...AND it saves everything you look up so you can go back and study the words and phrases you didn't know! It is absolutely priceless. I recommend using the mobile app along with the browser extension on your computer for the full experience. I went premium after using it for a while... it is well worth it, but if you can't do that, it's fantastic even without the premium.
