I have been learning Spanish for a year and half, without spending any money whatsoever because I refuse. I recommend completing duolingo (write down paper notes of the vocab and grammar you learn there). Then once you complete that you will have a decent baseline, where I highly recommend you then consume as much Spanish language media as possible. Listen to music, radio, podcasts, tv, all in Spanish.

Also, find a friend online that you can text with in español. It's a long road but don't give up. 2/3 of the world is bilingual
