An intriguingly designed (and stupidly named, bearing in mind the popularity of SmartFM for listening to music) adaptive learning tool that attempts to improve the effectiveness of self-paced learning by reminding you about stuff relating to your learning goals at the right point on the Ebbinghaus forgetting curve. In essence it's a sequencer for memory-based learning. Purportedly based on brain science and using a very strongly cognitivist approach, this actually looks like quite a useful way to remember stuff if you use it in a disciplined way, although the effort and hassle of actually using the application may limit its utility for many people.
