Introducing Triggertrap
I got a chance to try out Triggertrap. It's a camera remote that includes two cables and an application. One of the cables is a dongle and the other one is a cable specific to your camera. Application is available in the Apple App Store. It has two versions, free and paid. Free version has only few functions, like basic cable release, bulb, seismic and timelapse. Paid version has much more functions, for example eased timelapse, facial recognition, hdr (high dynamic range), hdr timelapse and motion detector. I noticed that some of the features in the application can also be used with the devices internal camera, but the problem with that is that you can't easily see where the camera is pointed, which makes the framing hard for you.
