I wonder too - last time I tried faceapp it did a very convincing gender swap on me, but the face changed significantly with every photo I took - depending on angle, lighting, who knows? I began to suspect to wasn't making 'me' into a woman at all, just superimposing a female face that fit. (One of the best transforms actually looked like my wife, which was a moment for Freudian reflection).

Anyway, unless faceapp has improved a lot, I'm sceptical this guy was always able to show as the same 'person'.
