This app is only available on the App Store for iOS devices.
Use DOFMaster to calculate the depth of field in your photographs. You'll be able to select the lens and f/stop combination that provides the zone of sharpness you need. Use it to calculate the hyperfocal distance for landscape photography.
DOFMaster calculates total depth of field, near focus limit, far focus limit, and hyperfocal distance.
Depth of field can be calculated for any film or digital camera. Select a pre-set format (e.g., Canon DSLR, 35mm film, compact digital, Super 16, etc.) or a custom circle of confusion.
F-stops range from f/1 to f/64, with 1/3, 1/2, and full stops. Focal lengths range from 3mm to 1200mm. Use feet, meters, inches, or centimeters for input and output.

Almost perfect! v1.0.1
This is a simple to use app that isn't cluttered with a lot of bells and whistles. It does just what it was intended for - gives you the DOF/Hyperfocal distance based on your input. I do agree with others that it should have the numeric keypad as default for inputing your focus distance. Also, it would be nice to be able to toggle between the original calculation and the hyperfocal calculation after you press the "HD" button. Other than that it is the perfect app for calculating DOF.
Just downloaded this app today. I compared it to a hand help Hyperfocal chart that I owned and it was spot on. HD calcs the correct focus point and the table shows the area of focus as 1/2 of the Hyperfocus distance. Perfect. All I had to do was set it up for my camera type and from then on just input the lens mm, the f stop and you are ready to calculate. Now I don't have to carry around an additional chart.
This is a must have in the field when shooting. The numbers are spot on and as mentioned in other reviews - that is what really matters. If your camera is not in the list in the app you can go to the application website and click on the digital CoC link. That list is up to date and shows what the CoC is for your camera.
