AOPA tries Xavion in six simulated power-off approaches and determines:

“[T]he $99 Xavion app is an impressive piece of safety equipment that could be a lifesaver in an actual engine and/or avionics failure. It vastly enhances pilot situational awareness by constantly showing airports within gliding range at a glance, and its terrain database and GPS-derived synthetic vision depict mountains, rivers, roads, and valleys in colorful detail.”
