Ever wondered why the mountains in your photos look out of focus at f22?
This app will help you with the calculations required to minimize the diffraction effect on your photographs. I use it for landscapes, but you can do the calculations starting at 0.3 meters. This is a must if you want to do the mentioned calculations fast while on location, especially if you already invested in a good camera an lens and want to get the best out of your system.

A must have for landscape photographers!
Where should I focus, what aperture value should I use? Using an arbitrary aperture value is not going to give you the sharpest image, do to defocus-blur and diffraction. Somebody has already figured this all out and has put it in very easy use app :)
Terrible interface
Great app but the new interface colours are terrible. Please put it back to the old colours.
Excellent!
Excellent work George! New interface is awesome! Please keep it up. I didn't like icon colours though.
Nice rewrite. Great UI
Great UI in the new version
Great App if You Value Sharp Images
If you spend big bucks on a high resolution camera and lens, then you need this app to get the results you want.
Say you are shooting an interior with a 24mm lens. You need everything in focus that falls between 5 meters and 20 meters. Where do you focus and what aperture do you use?
If you guess wrong you will not get your optimum image.
The answer is you focus at 8 meters and use an aperture of 5.6. And if you are using a high resolution camera like the Sony A7Rii, your results will be off the charts.
Get the app.

Not terribly useful.
The description of this app sounds promising, but for landscape photographers who want a deep depth of field it really does not tell you what you don't already know. Additionally, it has an arrow of where you should focus but it does not tell you what that number is, it simply just had an arrow between 10-15 feet. Not very precise when that is kind of the point of this app. If I had to do it over again I would not purchase.

Don't buy
This app is absolutely useless!
Eye Opening App for Photographers
This app is great for teaching purposes, as well as out in the field. The fact that it approaches the task of setting the aperture from the photographer's point of view - give it the near/far distance and it gives you the aperture helps my students quickly achieve better quality images. Additionally they visually see the affects of changing positions of the subject and how that impacts the best aperture. Interestingly all the calculations (if you read the provided information) show that lens manufacturers should simply make lenses with aperture ranges around the "sweet spot" and forego those narrower apertures. This eye-opening app should be on every photography instructor's list of equipment for class.

Values are way off
Doesn't work. Needs to be updated.
Great Tool
I have five or six of the DoF tools but this works in reverse and for a landscape photographer is more useful. I expect it will also make macro work much easier.
Easy and quick to use.
Somewhat different approach to traditional DOF calculations, but in practice more helpful.
A course in exposure, DOF and focus
I was about to create this app myself and found this wonder. Study this and associated articles on the web and your shot quality will have a step function in improvement. My best LF work happened when I began working in the image space.
Every photographer, particularly landscape shooters, should own this app.

Awesome
No more calculations, charts, this app brings all the variables into play. Very easy to use, and I always have it with me. My Landscape photography has improved sense I started using this app. My old Ais lenses are getting a good working out.
Amazing.
Of all of the applications on my phone, this is by far the most useful. As a professional photographer of 17 years, I personally recommend this app to any budding professional.
So useful.
Shooting on large format camera. Ideal for me. Thank you.
