I am using Pleco on my phone as an SRS for Mandarin. (Setting it up to be a proper SRS hurts, though.) The absolutely great thing about Pleco is that it is a great dictionary app and a document reader in the same app. When you see the solution of a flash card, it usually includes a handful of example sentences. You can then tap on words in these sentences and see their definition again... It is a little like getting stuck in Wikipedia - sometimes I spend half an hour only reading examples starting from my current flashcard. I have no solid statistics on this, but I feel that the context really helps me to memorise things :)
