IMHO, WingX is better than Foreflight. However, the last time I saw FF was 18 months ago and it had to have improved. Regardless, I believe WingX is a better app, better focused on the needs of the SPIFR user. Lastly, the few times over the last 30 months that I have required support, it was a simple phone call away. If it is not too late, look at WingX Pro 7.
