For the sailors among us…
I’m developing an app for the calculation of Velocity Made on Course (VMC).

First of all, the simulator totally ignores the nautical distance format. The watch does format it well so it’s not a big deal.

The second issue is that I don’t see any option to get the bearing and/or coordinates of a selected POI. Only the distance is available. This makes the VMC calculation very inaccurate since the distance is measured in meters only.

The preferred way would be to calculate the VMC with the speed and angle

speed * Math.cos(heading - bearing);

All of the values are known, except the bearing to the POI. Is there any way to get this information?

Here’s my little S+ app called “Constantin” that shows either pace or HR in split view:

Graph on the left and delta / current / average on the right.

Top button switches between pace and HR.

When I run I tend to have quick glimpses on my watch to see if I have a tendency to go too fast or if my HR climbs. So I have designed a view that shows me if I’m actually deviating from the average in pace or HR or not.

It’s evolving

I went for canvas instead of default chart so that I can have the latest value exactly in the center.

@Łukasz-Szmigiel Hope to see this in the Store soon—it looks incredibly useful.

@Bigb0zz thanks, I just filled in the form to become a Suunto Partner. I’ll upload it after I’m accepted.

It should be possible to just calculate the bearing yourself.
I think we are looking at the loxodrome here:

@wilson75 thanks for the heads-up! Yes, that was me. After seeing such great feedback here and on Reddit, I decided to join the Partner Program and bring the app to the SuuntoPlus Store for everyone to enjoy.

@guderaber can you opensource it? I’d like to pitch in. Me & Claude just deved the climb log app and debuged the whole issue that it crashes/can’t be enabled.

@Egika That would be possible if the coordinates of the POI are known. The problems is that the only value for POI seems to be the distance. (/Navigation/Poi/Active/Distance)

Target location (/Navigation/Targetlocation/Distance and /Navigation/Targetlocation/Coordinates) does seem to provide this information but when you select a POI the target location remains empty.

Constantin ready for release!

Data on the right refreshed once per second.

Data on the chart refreshed once per 6 seconds with an average from those 6 seconds to make the chart smoother. Also, the chart positions dynamically up and down every second (the dot represents current pace / HR).

Two modes available - one for pace, second one for HR (switched with top button).

Designed to make running more constant.

@Łukasz-Szmigiel Very nice! Can’t wait to try it out.
