I started by using HelloChinese to learn; it was difficult at first but learning a new language is difficult. I know if you are okay with talking with people you can try and find the apps that let you talk with native Chinese speakers, I ran into the issue though where they just wanted to practice English and their English was much better than my Chinese, so, maybe let yourself get conversational before you start using talking apps.
In addition, I use Pleco for my flash cards and for a really accurate English <--> Chinese Dictionary (it may support Spanish as well). I have a premium account, if you'd like premium features DM me and we can swap Matrix info to get it on your account.
