I’ve been using related material since the ‘80s . . .

. . . and this is my favorite source for braintertrainment now, without a question. The programs are effective, the music is well designed, the sound effects are well tuned, it’s all designed to work well together, the music moreover is very pleasant and comes in a wide variety . . . both this and the equivalent iOS app are superb.
