Quickly opening the camera app can be the difference between snapping a great iPhone shot and losing that moment forever. The camera shortcut on the lock screen helps when the device is locked, however jumping to the camera when using other apps takes time. The jailbreak tweak quickCam eliminates this problem by making the camera available from anywhere.
Once installed, there are no settings to configure. QuickCam works by adding an Activator option that opens quickCam. Just about any gesture can be set to open quickCam from anywhere. For example, quickCam can be invoked from within an app by swiping on the status bar.
Opening quickCam results in a camera preview being overlaid directly above whatever is on the screen. Toggles in the window control the iPhone flash or switching between front and back cameras. A shutter release button snaps photos directly to the camera roll, right from the tweak. QuickCam is available for the iPhone only, and requires Activator to be installed.
quickCam is available from Cydia on the BigBoss repository for $0.99. Check here for instructions on how to jailbreak iOS 7.x with evasi0n 7. You can also find out how to purchase and install Cydia tweaks with this guide.
