Some updates on the Woo Screen app. I made it compatible with older Wear 1.* watches (like Sony Smartwatch 3, thank you for the idea Olaf
). There wasn't any extensive testing done on Wear 1.* watches yet, but at the first look it behaves the same way as on newer devices. The only thing I would advice against is watches without any buttons (like LG G watch). They use screen palm gesture instead of a power button, so whenever such watch gets under water, it exits any app that is currently running.
Speaking of testing, I had 2 watches on during a session today
. On one watch I had Woo Screen app and on the other a new GPS speed tracking app I recently wrote. Woo Screen behaved flawlessly today. 4.5 hours session, not a single problem. The watch battery lasted all 4.5 hours and still had some juice left. That's not bad considering that air temperature was around 7C today
. Many falls and swims for the board - the app re-connected with Woo every time. Never exit the app either - the screen gets black under water, but turns right back on when you tilt your hand (this is how it behaves on Polar M600, on Nixon Mission the screen doesn't turn off at all).
The watch running GPS speed tracker lasted only 3 hours, so yeah, adding GPS tracking to the Woo Screen app will kill the battery much faster
Also, I found the speed display a bit boring. It is about the same speed most of the time and with little practice you'll know how fast you are going without looking at the GPS. It would only be useful if you race or do speed trials. Reviewing tracks might be interesting though. I hope to shortly finish and release a free GPS tracker app designed for watches and water usage. After I get some feedback on a stand alone GPS app, I'll add GPS feature to Woo Screen app
