Pushupfu is a pushup challenge game for the iPhone and iPod Touch. This game uses the accelerometer to monitor your pushups allowing you to compete with others or just train to achieve a higher total number of pushups.

For this app, you?ll need to have the athletic armband for the iPhone and iPod Touch. The reason being is that there?s a specific way to attach this device to your arm that the app shows you in order for it to monitor your progress. Once you?ve strapped it on correctly and gone through the training of how to use the app and confirm that it?s working properly, you?ll be all set to use this app how you like.

Your options now include following the 10 day training program or battling someone head to head. Whatever you choose, when you?re finished doing the pushups, you?ll get to see your results page, which shows which set you were on, the number of reps, time took to complete, and warnings for speed and half pushups. This is really useful if you?re looking for a way to figure out exactly what you need to improve on.

The app is great and really easy to use, the issue is that you really do need an armband for the iPhone to truly get the full use out of it. This is the first app for the iPhone or iPod Touch to require a peripheral for it to fully work. Other apps have required you to use a computer, but as that?s standard for syncing, this is really something new. If you?re a fitness buff or just like competing and actually have the armband, definitely check out this app.
