Speaktribe is a pretty cool one, even though I'm not a big fan of the voices it comes with. 
Other apps I like: 
- Language Zen https://www.languagezen.com/learn
-  Learning Spanish http://learningspanish.thisiscool.com/index.php
- Mondly  https://www.mondlylanguages.com/
- Spanish Injection https://play.google.com/store/apps/details?id=com.immersia.inj.spanish.gplay
And of course duolingo and memrise.

And also thank you Zach, I've already bookmarked the link of Bill Worden's lectures. For the first look, I didn't like it. I thought it's a learn platform like futurelearn, that's very helpful but the lecture is all for a week and I can't help myself to plan it well. But then I saw it divides into small lections and it seems very cool. I will try it this weekend when I have more time. 

I'm using Duolingo to learn Spanish. It helps me learn new words. And it seems work well on computers rather than phones.
