Understand trip statistics and charts

The Statistics screen shows the numbers and charts for the selected trip. To open it, tap the statistics button in the top bar of the map. Tap it again to go back to the map.

Geo Tracker calculates the statistics while you record, and again when you import a track. It filters GPS noise along the way, so some values differ from what a simple sum of all points would give. This page explains how each value is calculated.

All values use the units you chose in Settings → Display → Measurement units.

Speed and time

Value	What it means
Track length	Horizontal distance of the track, as measured on a map. Elevation changes are not added: GPS altitude is too noisy, and even on a steep 10% climb they would add only about 0.5%. Breaks between recording segments are not counted either.
Max speed	Highest speed during the trip. Geo Tracker filters out GPS errors, so a single bad position doesn’t produce an unrealistic maximum.
Record duration	How long the recording was running, from the moment you started it. Pauses are not counted.
Movement duration	The part of the record duration in which you were actually moving. See Moving time and record duration.
Average speed	Track length divided by record duration. Stops lower it.
Average speed moving	Track length divided by movement duration. Stops don’t affect it.

Moving time and record duration

Record duration is the time the recording was running. It starts when you tap Record, even before the first position arrives, and stops while the recording is paused.

Movement duration counts only the time you were moving. Geo Tracker estimates it from your positions, so it may not be 100% precise.

For example, on a 3-hour hike with 40 minutes of breaks, the record duration is about 3:00 and the movement duration about 2:20. Average speed is calculated over 3 hours, Average speed moving over 2 hours 20 minutes.

Altitudes

Value	What it means
Altitude difference	Max altitude minus min altitude.
Max altitude, Min altitude	Highest and lowest point of the trip.
Vertical ascent	Total height you climbed, added up over all climbs.
Vertical distance	Total height you climbed and descended, added up. It’s never less than the altitude difference.
Vertical speed	Vertical distance divided by movement duration.

For example, if you climb from 0 m to 100 m, descend to 50 m, climb to 150 m, and descend to 100 m, the climbs are +100 m and +100 m and the descents are −50 m and −50 m:

Vertical ascent = 100 + 100 = 200 m
Vertical distance = 100 + 50 + 100 + 50 = 300 m
Altitude difference = 150 − 0 = 150 m

GPS altitude jumps by several meters even when you stand still. To keep this noise out of the ascent and vertical distance, Geo Tracker ignores small ups and downs and counts only real climbs and descents. That’s why these values can be lower than in apps that add up every change.

The altitude reference (WGS84 or sea level) and a fixed correction can be set in Settings → Location, under Altitude.

Point count

A track is not a continuous line: Geo Tracker saves it as a series of positions, called points, and draws the line between them. Point count, under the trip name, is the number of points in that series. How many points a track gets depends on the recording profile: positions that are too imprecise are not saved at all, and a higher frequency or a smaller min distance saves more points. More points draw the track in more detail, but also make it take more space and exported files larger.

Slopes

Value	What it means
Max slope	Steepest climb.
Min slope	Steepest descent, shown as a negative value.
Average slope	Average of all climbs and descents. On a round trip, climbs and descents largely cancel out.

To change the slope unit, go to Settings → Display → Measurement units and pick it under Slopes.

Charts

The Speed chart and the Elevation chart show the speed and altitude along the trip. Tap or drag on a chart to read the value at a point, and open it full screen for more detail.

The x-axis can show:

Distance: distance from the start of the trip.
Duration (S), recorded segments: time of the recorded segments only. Pauses and breaks between segments are cut out, so the segments follow each other without gaps.
Duration (O), overall: time since the start of the trip, including pauses. Pauses appear as gaps in the chart.

Switch the axis above each chart. To change the axis all charts start with, go to Settings → Display and pick Default x-axis for charts under Formats.

Ski statistics

Ski statistics count your downhill runs. They work for skiing and snowboarding, and for mountain bike descents too. Ski statistics are part of Geo Tracker Pro.

To see them, open the trip’s statistics and tap Show next to Ski statistics. This marks the trip as a ski trip, so the section stays open for it. Tap Hide to unmark it.

Value	What it means
Number of slopes	Number of downhill runs.
All slopes length	Horizontal distance of all runs together.
All slopes duration	Time spent going downhill.
Average slope length	All slopes length divided by the number of slopes.
Average slope duration	All slopes duration divided by the number of slopes.
Average slope speed	All slopes length divided by all slopes duration. Lift rides are not included.

Short drops don’t count as runs. Descents that follow each other without a climb in between count as one run, so a short flat part in the middle of a slope doesn’t split it.

To hide the ski section for all trips, turn off Ski statistics in Settings → Display, under Appearance.
