v4.0: most common pool length values and watch screen format & fields can be configured in watch. hold "up" button for three seconds. small adjustments heading. Several cosmetic changes.
v4.1:
calories can now be selected as screen field in watch menu.
new app setting "DEBUG" which enables writting of accelerometer and heading data @10Hz in FIT file (default disabled)
new feature autolap can be configured in watch menu (default disabled- when enabled, it triggers a new lap every n lengths, where n is a configuration parameter)
several bugfixes and memory enhancements.

Would it be possible to adapt the app to be installed on Fenix 3 and FEnix 3 HR ?

Thanks a lot

Hi Daniel,

I have found that app works great in one pool, and in the other it is almost unusable. In most of the cases I get about twice the laps I actually swam :)
The pool where app goes haywire has its bottom and walls are made of stainless steel - this could be interfering with the compass readings your app uses.

If you want I can provide example fit files with debug info, maybe additional filtering could sort this out.
I guess apps that are based on accelerometer would behave better in such case.

Thanks for the app and the effort you put into it,
Krzysztof.

Hi,
sorry for the delayed answer. Somehow I missed the notification for your post.

yes, this is one possibility. Any devices creating a magnetic field close to the watch will affect the compass.
I have also had an issue a couple of times, that somehow the compass gets stucked and does not seem to react. I have the feeling it gets fixed by restarting the watch and/or shaking the wrist. But I am not 100% sure, as it has happened only a couple of times...
if this happens to you in he 2nd pool systematically every single day, I guess this means that a magnetic field is disturbing the compass, as you mentioned.

Thanks for the app! Like you, I have a 230 that I would love to use for swimming.

I've tried it a few times, but keep running into problems. I read the manual carefully, and have tried my best to conform to all the protocols, but it keeps inconsistently adding extra laps.

For reference, I'm a pretty poor swimmer, so maybe my terrible form is setting it off? But it seems to happen a lot faster than 10 seconds.

I swim in a 25m pool, and do an immediate turn at 25m, and then a long rest after every 50m (by pressing the pause buttom). All of the intervals show up perfectly (about 1:10 swimming and :50 resting), but the distance is off a lot (registers anywhere from 50m to 75m to 100m). In one case, it seemed to be working fine, but then partway through the workout would not register distance at all, although the compass readings continued to work it looks like.

I've attached a couple of .fit files if you get bored. If it is just user-error, let me know and I'll continue to try to smooth out my form. I can't tell if the extra laps are getting added in the middle of my lap, when I do my 25m turn, or perhaps when I stop and restart the watch at the 50m rest.

Thanks again!

hi,
i have seen your post in my blog. i will answer you there :)

Hi Dani,

Here we go again. I'm dying with this thing. For whatever reason, I just cannot get it to work.

Below is the link to my latest swim.

As you can see if you zoom in on the first 5 minutes, it looks like between 10s-15s the compass correctly calibrates to 1.00. But then at 32 seconds, when I make my 25m turn at the far wall, it only dips a little bit and then goes back up to 1.00. At 1:18, when I make my 50m turn at the original starting wall, it drops down to -1.0, but then immediately jumps back up to 1.00. It does not recognize turns at the far 25m wall, so, it seems to think that all of my swimming is going in the same direction.

Oddly, it does briefly change compass direction at my 50m turn (the -1.00 at 2:31 and 3:53 are all turns at the original wall), but the compass doesn't stay down there, it just immediately reverts to 1.00.

At 9:10 and 13:30 I paused the watch to fix my goggles.

Any ideas?

Hi Daniel, thanks for the app. It seems that when the pause button is used, the total activity time still includes all pause moments. Wouldn't it be more logical if pause time is not included in the total activity duration (like for running/cycling activities)?

Thanks Daniel, I must have overlooked that post. You write that in a next version you will add two fields so that GC shows it correctly. Did you already do that, because for me GC still shows the issue.
