I have an Android phone. Is there is built in World Walking pedometer I could use?

Some higher end Android devices come with a built in pedometer. This will log any steps you take while the device is powered on, and World Walking can be used to bank these steps. To start counting steps from your pedometer, go to the Settings page and enable the pedometer feature (if your device is not compatible with this feature, the option won’t be available).

From then on, whenever you open the World Walking app, it will check how many new steps you’ve accrued, and if it’s more than a few hundred, the app will add these steps to your bank. You’ll receive a popup telling you when steps have been successfully banked. Bear in mind that this accounts for all steps you take when you have your phone, so if you use the GPS tracker you may end up banking the same steps more than once.
