For me, Anki reviews are a morning ritual. I do whatever it scheduled for the day. Then, I take time to review weaknesses. Then I move onto doing my actual projects. A combination of project experience and curiosity inform me as to what new Anki cards I need.

So yes and no to your question. Anki by itself isn't useful for learning to program. Anki as part of a larger personal development system can be pretty effective from my experience.
