SimpleExposure app for iPhone and iPad

This app will turn iPhone into exposure meter for cameras.　
It calculates the EV value at the present moment based on the photo taken with the built-in camera of iPhone and displays the combination of preferred ISO vale, exposure value and shutter speed.
It also writes each original value set (ISO, exposer, shutter speed) on the photos taken with iPhone and views as a sample. The sample will be saved simultaneously.
You can see the saved images on a list of images in the history window.
The shutter sound can be reduced by the volume button. However, it becomes the normal volume if it is set mute.
The ranges of ISO vales, exposure values and shutter speeds are as follows.
ISO values:
"25","50","100","200","400","800","1600","3200","6400","12800","25600","51200"
exposure values:
"F0.7", "F1", "F1.4", "F2", "F2.4","F2.8","F4", "F5.6", "F8", "F11", "F16","F22", "F32"
shutter speeds:
"60","30","15","8","4","2","1","1/2","1/4","1/8","1/15","1/30","1/60","1/125","1/250","1/500","1/1000","1/2000","1/4000","1/8000"

NOTE:　However this app calculates ISO value, exposure value and shutter speed based on the photos taken with the built-in camera, we are not able to guarantee the accuracy of these values. It is not possible to set these values to iPhone camera itself.
