I joined a language learning company recently and just released this Spanish app for Android devices called Bueno... entonces (which means great, so... and is a common "filler" phrase in Spanish). If you're a non-ios owner and a non-spanish speaker, and you don't mind mildly ribald humor, you will genuinely like this app. It had already been written for iOS but I partnered w/the original owner to release for Android so it's a bit of personal labor of love for me.
I had to speak 4/5 languages for my job, and in the process of learning them, I've landed on a pretty solid language learning method that brought me to fluency (C1) in French in 5 months, with about an hour/day time investment. This website shows you how to do the same!
