Don and HOOK:
The 8 inch Android I use with IFY is WiFi only and cost only $140 from COSTCO. The 8 inch Apple tablet cost over $400 and I had to get it with phone availabiity to get the on board GPS. WHEW! I have tried to stay away from apple products for that very reason.
The basic subscription is $99. I don't have synthetic vision.
As you have surmised, I am adamant on ocal warnings since this cat has no more lives left after surviving the midair.
Along with the smoke system and rear view mirrior to see up and behind the voice alerts is icing on the cake.
All that said IFLY has served well for these many years and it would still be my go to APP had it had voice alerts.
It will also be nice to have flight logging.
However, it would not be appropriate for me to advertize Foreflight features on an IFLY forum. You Tube has all you need to determine these festures. So the comparisons I will be doing will remain personal.
PS: One feature I'd like to see on both platforms is active glide ratio. I had this on an early App many years ago, but I can't remember which one and can't find it.
It looked at your GPS ground speed and altitude loss to arrive at the glide ratio. It seemed to be accurate. In the event of an engine failure, and I have had four in my 8,000 hours, you could manipulate pitch for the best glide range. This should be a simple feature to add to any platform. I believe I added thos to the IFLY wish list way back when I first got the APP.
