[App] Barometric altitude Amazfit Pace - Amazfit

Is there a posibility to install Android app that use barometric sensor to calculate altitude, because GPS altitude works slower with much more power used.
Thnx

use trial mode
Running mode uses GPS for altitude. trial run mode uses the barometer for altitude.

Interesting. Which one should be more precise - GPS or the barometer?

GPS if you're on flat open ground with no trees and clear sky. If not then trial run.

Do you know what the other sport modes use for measuring altitude?
So far my experiments show the following:
Climb - very inaccurate , shows wrong altitude with deviation of more than 150 meters;
Trail run - absolutely precise measurement :good: (does it really use the barometer instead of GPS?!);
Run - kind of strange, but the Altitude Graph is displayed this way in my activity reports, even when I'm in the mountains:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So no altitude information about this activity.

wrong Altitude
in which distribution the altitude is calculated correctely? on a flat path runnig I get change of altitude around 400m.
I get values completely wrong. I have Stratosfied now

---

Trial mode is accurate for me (on Stockified and Stock on Pace). Cycling seems to use the same method as running, they both give crazy results ( 400 meters below sea level when I'm on flat ground above sea level).

---

Pace has a known bug that the altitude gets "stuck" after an activity, restating the watch should fix it for the next activity. I'm not sure if it happens with Stratos as well.

---

I found the initial altitude value can be very inaccurate
Then during the activity the elevation gain is quite accurate (with an error less than 5%) but with an initial value completely wrong the current value is unreliable.
It's a pity to have both GPS and barometric altitude without the ability to see and calibrate them
I use it often in mountain and having a reliable value is important not only to see the difference in altitude but also to forecast weather change
any suggestion?

I don't know from where you have this info, I searched for it but couldn't find some more informations on it
.
My experience with altitude is, the first 30s of every outdoor activity the altitude is allways wrong. Later it gets better but I could not see a difference between trailrun or running or cycling.
BUT
I don't use the Phoneapp to have a second look at the activities but export it with python scripts and look at it with some other software. It can be, that the Phoneapp is using online altitude value models to correct wrong values, but that is just a guess.
The new Chinese beta ROM (CN BETA 2.0.6.0.12) has a "use 3D" setting on all the outdoor activities, which I'm not sure, what it is for. Maybe it is to activate the Altitude measuring via barometer.

Sometime I have the same problem of flat altitude with my pace on trial mode. I’m on 2.6.1.0.
In run mode I have inacurate result with 280m climbing instead of 80... since the beginning. I have my pace since 15 mounth

---

3D mode means that not just the horizontal distance is used but the vertical as well. So in steep area it will be longer.

3D data can be set and enabled in the sports settings. When 3D data is triggered, watch will
calculate distance using both your elevation change and your horizontal movement over
ground as shown above.
