I've used Rosetta stone myself and I would NOT recommend it for absolute beginners. It works best for syntax, vocab, and pronunciation. Rosetta stone should not be used by itself and I would discourage it from being used to start. If after you gain the basics of the present tense and grammar you feel it could help you and you want to pay for it, I'd say go for it, but remember, Rosetta stone alone won't make you fluent. I did see a big improvement in my Spanish from Rosetta stone and I still can picture the image associated with the vocab I learned in my head. In the beginning I honestly feel like classes help the most. If that's possible for you, I'd take a beginning class.

Hello Vlad. I haven't use the Spanish version of Rosetta stone but I did with the English version. To be honest I didn't learned as much I wanted to, I learned basic vocabulary and casual conversation. I think if you're interested in learning Spanish at the same level you should try bussu, duolingo, and memrise ( It is even cheaper getting these apps/courses than Rosetta stone) . If you want to learn as fast as you can you can try using all at the same time. What I do when I'm learning a language I try to emerge myself into the language. I download as much information that includes listening to audios watching movies in the languages, translating with the minimum knowledge that I have etc. I try a bunch of stuff. I think one of the most important things to accelerated your learning is to talk and write. You can try writing notebooks and asking questions here so you can get more associated with the language. ( I know maybe I said too much, but I hope it was helpful to you...) I hope you the best! :)

Babbel is pretty good for beginners! You can do a couple of lessons for free to try it out and pay if you want to do more. I've used it for both French and Spanish and it's nice. It does vocabulary, grammar and conversations. It's pretty complete. https://www.babbel.com/
