Best for less $

I purchased both this app and PhotoCalc. They both work well and do a good job calculating the DoF, but you save a dollar using PhotoBuddy. The gray-scale wedge is a great idea for getting the white balance right. I havent used it yet, but plan to next
time Im out shooting. I wont have to worry about carrying a gray card since Ive always got my phone. Well done application. The only problem Ive found is with the Sunset time always showing 0:00 (the sunrise works well). Highly recommended.
