P90X
Especially if you’re already a P90X user, you’ll find this companion application extremely useful for tracking progress, setting goals, and staying motivated. You can also log non-P90X workouts and nutrition information, similar to just about every other fitness app on the market. There is also, of course, a social component, so you can design a profile share progress with your friends.
Real P90X Content
The real value of the P90X app comes at quite a price. For anywhere from $6.99 for one workout, to $59.99 for the entire archive, you can gain access to real P90X workout demonstrations—in video form—right from you iPhone. The cost is significantly higher than you may want to pay for a mobile app, but if you’re thinking of investing in the P90X system, this may work better for you than the DVDs, and will give you similar quality and greatly increased portability.
