Yes for Sports Tracker software with watch you just control the app in phone. That's why I like Woo screen more because if it could be used without phone, like at water I would. On snowkiting this is a bit different.

I was finally able to test max 60 seconds speed metric on water yesterday. It turned out to be a very useful information - very interesting to see the jump take off speed. The only problem is that interface of my app showed jump and and take off speed on different screens. I made some changes - hopefully I'll test it on water soon...

Yeah that my suggestion of the take-off speed came directly from kinetic and potential energy equations: 1/2 * m * v^2 = m * g * h -----> 1/2 * v^2 = g * h so only variables are v (take-off speed) and h (height). I started thinking could there be "jump efficiency" calculation in %, I mean how well you can turn v to h? Aleks, what do you think? Might be inaccurate due to 1Hz update and Woo's uncertainty of height but still could that be fun or even useful.

I still need to get to the water. Woo screen is working fine with couch jumping on my watch.

I can't come up with anything useful. For me personally seeing the jump height and take off speed is probably enough :D .

Tested yesterday again. Seeing take off speed along with the jump height is definitely a much better option.

I released app update - look out for version v0.71, should be available in the Play store in a day or 2.

There are a few changes. First of all, I fixed a bug on the phone app where jump notifications were not working on the newer phones. Sorry about that to everyone who got affected.

Also, there are some watch interface changes based on my on water testing:

- When GPS is enabled and the screen switches automatically to Jump screen (after a jump), it shows Max 60 sec speed instead of elapsed time.
- If GPS doesn't have a fix yet (so no speed is reported), Jump screen shows elapsed time as before.
- If you switch screens manually, Jump screen also shows elapsed time (you already have Max 60 sec speed on Speed screen).
- Automated jump display period shortened to 17 sec.

I know that switching of metrics based on circumstances might be a bit confusing - I wish I had more screen real estate to fit more data and avoid it. However, I tested this configuration yesterday on the water and I actually liked it. I think once you get used to it, it is not going to be a problem at all 8) . Give it a try, let me know if you have any suggestions :thumb:

Sure, I need to get own experience with that first.

What I was thinking something like:
jump energy efficiency: 75%
(how much kinetic energy by GPS is converted to potentional energy by Woo), maybe by coloring of speed if no more small information element is available.
