The official preparation page notes the program does not endorse any particular method (Official ASVAB: Preparing for the ASVAB (checked 2026-11-12)).
Which option is best for the AFQT?
Use the official samples for format, then practice the four AFQT subjects until the methods are steady. AptiStep is built for that part only.
Is the AptiStep app free?
It is free to download on iPhone and Android; an optional one-time in-app purchase unlocks full access. There is no subscription. This is not a recommendation over other options.
