Lastly, TriggerTrap can take over in the cold when you want to stay cozy inside. If you have two iOS devices, the remote Wi-Fi trigger modes let you control the app on one connected to the camera from another. Curiously, the sensor modes use the "master" device that you hold, not the "slave" attached to the camera, making those features far less useful remotely. It also doesn't work with modes that require the camera to be in Bulb mode.
Even given its few limitations, TriggerTrap Mobile dramatically expands your options for shooting more interesting photos that require a range of shutter speeds or other triggers, without requiring extra dedicated hardware.
