Probably not relevant to you guys in the States, nor to glider pilots anywhere, but the most popular Foreflight equivalent in the UK for GA pilots is Skydemon. Skydemon can now show Powerflarm traffic. It runs on may different platforms. If this encourages GA pilots to get Powerflarm it will be doing a favour to the gliding community.

You will get zero Flarm traffic and zero collision advisories.



What 9B said... This is no substitute for Flarm or PCAS.



Foreflight/Stratus are likely the most dependable and mature DFB/ADSB

products on the market.



That said, there is an incestuous relationship between the two that is

anti-competition and therefore certainly isn't in the best interest of

us, their customers. Unless there has been some very recent change or

some hacks that I don't know about, Foreflight only works with a Stratus

receiver, and the Stratus Receiver only works with Foreflight.



Buy either, and you are locked in!
