Displays the GPS speed, altitude and distance to selected waypoint. One is displayed on the watch face using the largest possible characters depending on the number of digits. The other is in a smaller characters below that. Both are always visible. You can display the current or maximum observed speed/altitude values. Current time is always displayed. # GPS Speed, Altimeter and Distance to Waypoint
You can chose between two modes. One showing speed and altitude (A) and one showing speed and distance to waypoint (D). You can switch between two display modes. One showing speed and altitude (A) and one showing speed and distance to waypoint (D).
Within each display mode one figure is displayed on the watch face using the largest possible characters depending on the number of digits. The other is in a smaller characters below that. Both are always visible. You can display the current or maximum observed speed/altitude values. Current time is always displayed.
The waypoints list is the same as that used with the [GPS Navigation] app so the same set of waypoints can be used across both apps. Refer to that app for waypoint file information.

App Settings : Select the desired display units. Speed can be as per the default locale, kph, knots, mph or m/s. Distance caqn be km, miles or nautical miles. Altitude can be feet or metres. Select one of three colour schemes. Default, high contrast (all white on black) or night ( all red on black ). App Settings : Select the desired display units.

Loss of fix : When the GPS obtains a fix the number of satellites is displayed as 'Sats:nn'. When unable to obtain a fix then the last known fix is used and the age of that fix in seconds is displayed as 'Age:nn'. Seeing 'Sats' or 'Age' indicates whether the GPS has a fix or not.

Low Power GPS Service : ## Low Power GPS Service
This app will work quite happily without this service but will use the Low power GPS Service if it is installed. In this case the GPS Service must be On for this app to obtain a fix. You may choose to use the Low Power GPS Service to gain significantly longer battery life while the GPS is on. Please read the Low Power GPS Service Readme to understand what this does.

There are a couple of things to consider when using the Low Power GPS Service. This app plus the LP GPS service together use a considerable chunk of the Bangle.JS memory. A large waypoints file will also contribute to this. The MAX values continue to be collected with the display off so may appear a little odd after the intermittent fixes of the low power mode.

Waypoints are used in [D]istance mode. Create a file waypoints.json and write to storage on the Bangle.js using the IDE. The first 6 characters of the name are displayed in Speed+[D]istance mode.
