Hi together,

I want to introduce you my Windsurfing app: WindsportTracker

you can download it from Google Play Store here:

play.google.com/store/apps/details?id=de.sunbits.windsporttracker&referrer=utm_source%3Dweb%26utm_medium%3Dseabreze%26utm_campaign%3Dseabreazepost

Windsporttracker is made for all windsurfers. So when you are very beginner or a pro, you both can see how you make progress and how you can optimize your gear.

The app can either record a session, or import GPX 1.0 / 1.1 and SBP files.
You see how much distance you sailed, how much of it you where planing, how long did you sailed and how long where you planing.
Also you see how many jibes (gybes) you made , how many where successful and how many where fully planing.

For the Speed sailors, you will also see: what's you maximum speed, your 10 bests, avg of 5 best and avg of 10 best speeds for: 2s, 5s, 10s, 100m, 250m, 500m, 1NM, alpha 250, alpha500, alpha1000 and 1h and 24h.

After having some sessions recorded you see this data in yearly and monthly statistics.

You can also add your gear, and get the same data by gear.
So after some sessions, you know your fastest board, sail or fin, or wich of those is your best jibing gear.

I still have other ideas to improve the app, so if you have any ideas feedback etc. it's always welcome and allows me to make the app better.
Hope you like it, and enjoy sailing

best Matthias

Your app is pretty smart. I'm still finding my way around but would like to be able to delete tracks that were uploaded by accident.

thank you very much :)

to delete a session or gear, just swipe it to the right .
after this you have 30 seconds to undo this -> just press the undo button wich appears afterwords

Very clever! I swiped tot he left because that's what I do to delete emails.

It took me a little while to figure out that I have to pre-populate the gear. I uploaded a track and then kept pressing on the gear thinking that I could choose, board, find and sail from there.

One other thing, your app seemed to be overly generous to the tune of about 0.3 of a knot. Which suited me fine!

yeah, some emails swipe right, some left. and some both, I choose right as I found it more convenient (at least for right handed people)

hm, what did you mean exactly with tune about 0.3 of a knot ?

KA72 had me down for 29.88 knots maximum and your app had me at 30.54.

Hi,

I just send you an in-mail, if you could send me your track, this would help me to check where the difference comes from.

I think its because of different accuracy filters. (maybe depend on file format as some formats don't have accuracy data included)
But need to see the track itself.

Iguess you used a track from 3rd Party device to analyze with the app and KA72 ?
would be interesting how a track recorded with the App would behave in KA72.

I could see a bunch of alphas in different colours. Is there somewhere that tells me which is which? Maybe you could have the font colour of the numbers match the colour on the map?

Hi,

regarding the difference for speed values.
I found the issue and will fix it. It happens because you track is recorded with higher frequency of fixes per second (5hz)
thats why all time related (2s 5s 10s) speed values are little different to ka72.
But I will fix it and then the app and ka72 should show you the exact same values. thank you for your help (didn't had a 5hz track before)

regarding the colors.
I'm collecting ideas how this could be solved best. so color of the value is option, have to try it, thought it may be to colored but lets see. Another option (but more complicated) is to put the colors legend directly on map.

but fore sure I will definitely improve this.

for now, pink color is your fastest value, the more it gets into green the slower the value is.

Good job Matthias.

I reckon making the font colour of the speed digits the same as in the map would work best. Especially if the legend is more work.

I wondered if clicking on the coloured part of the track would pop up the speed in a balloon. This is probably even more work.

Maybe some of the other speed measures could do the same.

Hi,

thank you :)

good ideas :) I will check wich one will fit best, or maybe a combination of two lets see.

what other speed measures did you mean ? you can click on the 5s 10s etc rows to see those values on the map.

ah yes, sure I will apply this for all speed values :)

I fixed the issue with the speed difference on time based measures (2s 5s 10s 1h 24h) , this only apply's to sessions recorded with high frequency (5hz updates) all others are already correct.

The fix will be included in the next update something in September (as I think the difference is little and only effect is the display in the app) to get some more stuff in as well.

I also checked why alpha500 is different, and found that ka72 shows a alpha500 which is 900m and uses a gate of 82m.
but as I understand alpha500 its maximum 500m and the gate size is maximum 50m

so now I collect more feedback, and will improve the speed colors etc. :)

Hi,

with the latest version from today, the difference in speed details are fixed.
also the performance for showing the session was improved.
Now you can also write a note about your session
and new session types: Foil, RS:X , Formula and Raceboard was added.

in the next update I will include the color legend for the different speed values.

feedback is always welcome :)

I re-imported the data I sent you and one small fix needed is that on the home page, the speed shown above the smiley face doesn't match the 2 second top speed in the details. Mine still shows above the smiley face as 30.54kn also as 30.54 in the next screen, but as 29.88 in the 02s detail detail screen.

Hi,

ah, thats because the value shown there is the top speed for one measure point. so mostly it's the speed for 1s, but in case you use a high frequency device, its even less then a second.
As your devices recored with 5hz, this is the top speed for just: 250 ms
this value is there for non speed surfers to give them an idea how fast the were, where speedsurfers should have a look into the speed details.

did you see the icon below as a smily ? because then I need to change it :D as it should show a fin :D

Hi,

sorry for waiting long of an answer. I was at the german speed windsurfing master and didn't had wifi there.

ah yes that value :) its the same as i mean. so the value here and the value on the next screen is the maximum you achieved on one valid point (points with high error rate are filtered) 2sec speed you see at the moment only on speed details screen.

maybe I should change this
