Choose your Unit
(km/h | mph | knot)
and Range *
for km/h (140 | 220 | 280 | 440)
for mph (100 | 180 | 220 | 360)
for knot (30 | 60 | 90 | 120)
*The range is different in every unit.
**999.9 is always digital
If you use a digital skin range will be deactivated and 999.9 or 999 is selected.
HUD [Head Up Display]
If head up display is ON, the speed output skin/interface is mirrored.
If you put your Phone/Pad under a windshield, it shows the speed correct mirrored through the window.
HUD works best at night or if its a little dark outside. Also turn up the brightness in the system settings if the reflection is hard to read.
Check to fix your phone, so it is not flying around while breaking. :-)
Audible speed alert is playing a sound, if your speed is faster then the alert is set.
Flash alert is flashing the screen, if your speed is faster then the alert is set.
The alert speed is set on the main interface.
Speed alert only woks, if Speedometer Pro is active in foreground.
Choose your preffered output between:
- Acceleration 0-XXX,
- Quarter mile ¼ mi
- Max speed
- ∅ average speed,
- current Altitude
for the left or right output.
On the digital skin with big speed letters:
- This options are unavailable. The screen space is used for the big speed letters.
- All GPS values are still udated and available on the result view/tab.
See your travel direction.
- Direcion in letters or degrees.
- Direction from GPS or magnetic sensor.
GPS directions are only updated on moving speed.
To choose the color, touch the color bar at your choice.
Keep GPS on in the background
If Speedometer Pro is running in backgroung, this values are updated:
- Distance [km, miles, nautic miles]
- Time on travel and stop/pause,
- Average speed on travel
- Max speed
[0-100 km/h,0-60 mph,0-30 knot]
- Max-, min-altitude
Continued use of GPS running in the background can dramatically decrease battery life.
To avoid speed detection while stand still switch the filter ON.
Switch the filter OFF if the speedometer detects no more speed or is lazy.
Why this filter:
This filter detects if the GPS position is always around the same point
and filters speed updates in this case.
This is good for:
- Avoid showing a smal speed while stand still.
- More precise distance tracking.
- More precise on move average speed.
(all GPS result values in one view)
a->b : Distance traveled
▶ ■ : Time on travel
▶ : Time on travel
■ : Time on stop/pause
∅ ▶ ■ : Average speed
∅ ▶ : Average speed on travel
max : Maximum speed traveled
(in meters or feet)
: highest altitude
: lowest altitude
(0-100 km/h - 0-60 mph - 0-30 knots
① : best acceleration
② : second best acceleration
③ : third best acceleration
How to detect a precise acceleration:
- The speedometer needs to accelerate constant from 0 to XXX in one step.
- The [● green/ ● red] point beside the acceleration output, needs to be constant green.
Quarter mile (¼ mi):
(0-¼ mile -> 0-402 meter in seconds)
① : best ¼ mile time
max : maximum ¼ mile speed
∅ : average ¼ mile speed
How to detect a precise ¼ mi:
On 0 speed, the [● green/ ● red] point beside the ¼ mi output, needs to be in green.
The speedometer needs to accelerate constant from 0 to ¼ mi.
The point beside the ¼ mi output toggles between [● green/● grey].
The point beside the ¼ mi output keeps the skin color until the next start from 0 speed.
(if you did your best time up to now, it wil be saved in the Results)
One of the most famose ¼ mi track:
Two result views
(result 1 and result 2)
The idea behind the two results:
(Keep one result for all the time.
Reset one result to detect/track a trip.)
The Results are constant updated while moving.
After a value inside result 1 or 2 is reseted, it restarts counting from this time/point.
- Values on the main interface
The active selected result values (1 or 2) are also active on the skin (main interface).
: Touch this button to see the map position.
≈ : An almost equal character in front of a value shows, that the value is calculated from
less exact GPS data.
