Hi Diydrones Community,
We just started to develop flight monitoring app for smart watches, We are aiming to have important features like when battery is critic watch will vibrate and warn the user, on the other hand drone pilots can voice command to change flight modes over watch(this will be hard to develop, we will do our best). Of course flight critical information can be also monitored on the watch.
We will add artificial horizon, however; this may not be useful since we can see the artificial horizon over phone, may be drone pilots wants this as a dedicated artificial horizon. We will also include a professional compass, barometer, and altimeter functions.
Currently we already developed a free app called CompassX for android wear smart watches, i think it will be very handy at the field for now. Let us know what you think and what you want?
