At first, the iSlate seems good enough. Yeah, you cant change "roll," and youre missing "shot" as an option, and the clapper sound is waaaay too soft, but hey, it only costs $2.99, so you forgive those things. Unfortunately, the real problem is that the clapper sound effect and the visual slap of the slate are not in sync! Theres a three frame delay between the visual clap of the clapper and the beep of the app. So...the very thing that a slate is supposed to be used for - syncing audio and visual - this app doesnt do. Im surprised I havent read other reviews that say this. Luckily, our camera also records sound, or we would have been majorly Fed. Only reason Im giving two stars is bc iSlate is still better than no slate at all... But an upgrade to address this sync issue would be SWEET.
