What's your favorite camera app for iNew v3?

[danyno1]

for video recording, I think in general capturing videos with manual focus setting makes much better videos.

do we have anything to make the camera focus on someone or something and then track it while recording?
for example like this : I want to set someone's face as focus point. where ever he moves , the focus point follows him.

on auto focus setting , when ever I shoot a moving object (for example a kid on
Swing moving forward and backward) I don't get a sharp and clear video. on play back video it gets so blurry and laggy and it's obvious that it looses focus all the time .
is it ok or I'm just being picky on a 180$ phone's camera a lot? is there any way to fix this or maybe get better results?

anyone??
