Triggertrap Mobile, the camera triggering app, is available for free between now and the New Year. The idea is to make it easier to give the mobile dongle (that costs $ 24.99) as a gift, without the recipient then having to buy the associated app. The app is available for both iOS and Android and allows a smartphone to perform as series of sophisticated camera triggering actions, when connected to the camera using the mobile dongle.
