I'm trying to preserve the best parts of the previous app, and extend it with major improvements.
I'm keeping the pointing arrow as-is.
The elevation bubble that shows the phone pointing elevation angle will be a cross-hairs, and the rocket's elevation will be represented by a rocket icon that rotates based on live data to show the flight path angle (like it does in the Blue Raven sim) and changes the icon for when it's under drogue and main (based on the vertical velocity)
It will track to the last available data, as before. I'm planning for it to also listen on a ground station coordination channel if your rocket lands outside of LoRa range so that it will automatically get data from the lost rocket feature if someone else is flying a Featherweight tracker, without having to ask around for it.
The icons above will show you whether your phone is connected to the ground station over Bluetooth, whether the ground station is connected to the tracker over LoRa, what the signal strength of that connection is, the packet success rate, and what the maximum GS-tracker range is based on the last distance and signal strength data. And separately, whether the tracker is getting good GPS data. I think this will help distinguish between loss of communication with the tracker and just the GPS losing lock temporarily.
Other planned new capability is a map view showing the rocket path and your path, and a channel selection view, where you can see what channels are occupied and who all the local Featherweight users are and what channel they're on. If it's your friend's rocket and you'd like to follow it, I'd like to make an optional alert when their rockets launches, with a button to monitor their flight with your ground station.
