Before starting a hike, start this app and let it

stabilize (find satellites and current location).

Then clear stats and go ...

Network reception on trails is poor, draining

battery and rendering many apps useless.

It's advisable to disable mobile network (3G/4G).

GPS works best with a clear view of horizons;

bodies, trees, and hills block signal. Carry phone

in pants pocket (not shirt) on the more open side.

Outdoors in a flat open area, most GPS units

can be accurate within 5 to 10 meters (yards).

Indoors it may be impossible to get any fix.

During GPS location updates (every N seconds)

status goes BUSY, then a beep sound indicates:

DOUBLE-beep at the start of a new lap;

HIGH/LOW beep for over/under speed threshold;

TRIPLE-beep for reaching milestones.
