VocApp.com - it's super easy, efficient & free.

You can learn in your browser or use an app for iOS/Android.

VocApp has built-in speech synthesis module which can help you with improving your pronunciation and comprehension.

Of course it uses spaced-repetition algorithm.

I use Anki on multiple computers, and have not encountered that problem. 

See if this helps if you haven't checked it already: https://anki.tenderapp.com/kb/problems/anki-says-my-clock-is-wrong

Aside from Anki, you can try the following options:

(1) Quizlet is a great option if you want to train your listening. While the pronounciation system might not be perfect (I have only tested it with Chinese Mandarin and Spanish), it still does an amazing job since everything is automatic!

(2) Memrise - while it doesn't have Quizlet's automatic audio feature, I love the point system (might just give you that little extra push to work harder if you love score keeping). They have recently introduced a daily goal setting feature and contests! 

(3) If you have iOS, definitely give Cat Spanish a shot! The cat might be silly sometimes!!! (spoiler below). I have only used the free portion so my recommendation is based on the free levels. 

(4) Duolingo (multi-platform) - for speaking! 

Hope that helps ^^ 

SPOILER

One of the questions the cat will ask you is if you like cat food, you have to say yes hahah or something like that ._. It has been a while since I last used it.
