This app sounds awesome!!
I've recently got myself a Garmin Forerunner 245 Music on sale and I've installed your app! Tomorrow it'll be my first sesh with the watch so I'll give your awesome app a go! Thanks for your work!

Great, Make sure you save the app ( click back, then save and exit ) & can you check in Garmin Connect Mobile that the jump info is in there still/.

Alright I went to Rosebud yesterday and had a 1.5hours sesh using this app (v3.1). Here's what I've noticed, some may be user error? If that's the case apologies:
- the up/down buttons won't scroll through the different screens
- none of my jumps were detected. Disclaimer, my highest jumps were probably in the 2 to 3 metres range. I don't jump super high yet

At the end of the sesh, I've exited and saved the activity. Within Garmin connect:
- the activity gets registered as "other" instead of Garmin's "kiteboarding". There's an option to change the activity type, but haven't done it because if you do, Garmin connect warns you that you may loose some data.
- there's no info about jumps anywhere. But maybe because it didn't detect my jumps in the first place?

Let me know if you need any other info that may help! Thanks!

Version 3.4 Released
Fix for crashes with watches that have small memory ( Garmin Instinct )
Tested to 299 jumps passed no problems

3.5 released with thicker connect IQ jump height graph bars

Been using this a little more for directional and hydrofoil jumps recently (so not able to do a direct comparison to Woo readings).

In my earlier comparisons I found it was consistently reading about 2m higher than Woo for the same jumps. This was a much older version. The newer version looked pretty true to my internal calibration (low jumps not registering, takes a decent jump to register). I'm also running probably the min spec of watch (garmin 245) so the sensors probably won't be as good as a fenix.

Soft landings with a foil kite seem to add on the hangtime a little more than is real but I'll happily take that as a compromise.

This is getting really good now!

Thanks, Hydrofoils and foil kites are a bit of a challange for the watch sensors due to the way they typically jump. Having said that I did limit the hangtime calculation in the latest version to what seems reasonable. What that means is if something strange happens like you loop the kite and go up again after an apex, or get a strange gust of wind on the float down, the jump height is still accurate but the distance and hangtime may not be.

You can go into calibrate mid session and select jumps missed, if you want the watch to work harder to detect them.

Just wondering of the suitable Garmin watches in the list, is there some that will have better sensors or get more accurate readings for your app? Any recommendations?

Yep.

Something with 5 buttons ( touch screen sucks in the water )
Something that has Music or Map cabability ( this normally means big application memory )
Any X or PRO Fenix model
Bigger the display the better to read
Not the Instinct - it has tiny memory.

This page has the Memory of all watch models.
developer.garmin.com/connect-iq/reference-guides/devices-reference/#instinct%C2%AE2xsolar
Click on the watch
You want more Watch App memory than 131,072.

Half a million or more is good, some have 1.31 million.


Instinct only has 98,000 so it cannot run even the base functions of my other app Sail Racer.

Good feedback Thanks ! :)

Since my last reported sesh, I've only had 2 more sesh (wind has been pretty bad) and in one of them, I forgot my watch at home LOL (I put it to charge overnight and forgot to grab it before I left).
But yesterday I've got the chance to use it again, latest version V3.8, super gusty winds, waaay overpowered on my 10m Naish Triad
The app registered only 3 jumps with the highest one been 3.7 metres. As a reminder, I'm still mastering the art of jumping so I don't send it super hard, specially when overpowered haha

Anyway, even when I probably did about 15 jumps, only 3 registered which still better than in v3.5 which registered none. I forgot to try the calibration though, will try that next time

Also, thanks for the other fixes, I can also confirm that the activity type it's indeed recorded as kiteboarding and the jump metrics (highest jump, hangtime, etc) gets recorded within the activity. Although one of them, (longest jump) seems off with 27.7 metres

Thanks again for your awesome work, let me know if there is any specific data that you might find useful

In my experience almost all jumps are correctly identified. I don't remember a case where I jump and do not have a new reading on LIVE screen. It even detects my jump transitions that are 1.0-1.5-2.0m high. Also as I reported above - my surfboard session produced zero jump records which was the expected correct result. So my experience with jump detection had been nearly close to perfect.
On the other hand I really doubt my ability of consistently reaching 6-8m heights So I am curious if someone can compare with e.g. WOO or any other means of measuring jump height.

I don't recomment the instinct.
Anything but that watch, it's been a nightmare changing the app just so it can run on it as it is so inferior to the other watches.

In my experience, jumping with good technique in strong winds ( overpowered ) that is where I also get a loss in the jump detection. If you are normally powered, and can send the kite and load up I think no problems, but in the overpowered condititions it's tending to disregard jumps.

Might be able to fix.

So 9 meters depends on if you are getting it by getting lofted, or by giving yourself a nice yank

Regarding the jump lengths, If you launch at 18kts, your almost doind 10 meters per second so 20, 30, 40, 50 meter long jumps are normal

100+ meter jumps and you've been lofted or are doing megaloops.

Mate, go for it.

Always interested to get more data, and see when it is good, and when it needs more work.

Hey Chops. Sorry to troll in here, but could you put a link to your app on your profile please? Makes it easier to find the details directly there than eye-balling all the thread responses for that info. Ta.
ps: bought a Fenix 5S. Finally get to run your app.

Kitejump:

Sail Racer:

Have a look at this list, and anything that has more than 500,000 Watch app memory limit should be fine.

Hi, it matters not at all.

The type of jump, and the way you jump has a bigger errect
