How to photograph it for identification

Raptors are usually far away and against the sky, so expose for the bird, not the sky, and take several frames as it turns: the tail shape, wing shape and underwing pattern show best in flight. For a perched bird, get the head and chest in one frame. Size is hard to judge alone; compare with a nearby crow, gull or fence post. The app names the likely species; confirm with the marks above.
