7 GPS Recording

One of the most exciting features of MyPersonalDiet is the GPS recording of your

outdoor workouts. It automatically records the duration and distance of a workout, and

you can review these values, your pace, even the course completed so far on a map, at

any time during the workout.

Note:

Results are far more accurate on a 3Gs than older models due to the device’s

significantly-enhanced location tracking capabilities.

To start a GPS recording, tap Today and then tap the GPS button to show the GPS

Recording screen. You might be prompted with the message “iMPD” Would Like to

Use Your Current Location”. This is shown whenever an application requires location

data. Simply tap OK to continue.

You will then see the message “Awaiting GPS Signal” (see Figure 27). This message is

displayed until your iPhone can precisely pinpoint your current location. Under a clear

sky, this may only take a second or two, but may take longer under different conditions

(cloudy sky, in a forest, surrounded by tall buildings, etc.) You can tap Continue if you

prefer not to wait, but the position and calculated distance may be inaccurate initially.

Figure 27: When recording a workout, it may take a few moments

for your current location to be accurately determined.

Then the recording screen is displayed (see Figure 28). By default, the live recording

begins as soon as you start moving, and pauses when you stop. That means you can put

your iPhone back in your pocket or backpack and go. If you prefer tap the lock button

to lock the screen; tap on it again to unlock the screen.

You can disable this “Auto-stop” feature via the GPS Recording’s settings, by tapping the

Settings button. The Settings screen also allows you to change lap type, the

distance and speed units, GPS coordinates formats and enable the device to beep when

the GPS signal is lost.

During the recording, you can enter laps (see next section) by tapping the Lap button or

view your current location on a map by tapping the Map button.
