• The interface gets an even cleaner, more spacious look. Simply slide the pointers to set focus distance and aperture (the old slider “thumbs” are now gone). Note that you do not need to keep your finger on a pointer as you slide it — you can move your finger to the side as you slide, all the better to see where the pointer is pointing.
• There are all manner of minor changes, including a more elegant colour scheme.
• The app is compatible with iOS 12 and with the various new iPhone X models.
Do remember that this free, pared-down “Intro” version is designed to give a mere taste of the very much more capable “Pro” version. Check it out here on the App Store.

A more pleasant colour scheme, plus several small interface tweaks.
Of course, all the new features of the last major upgrade are still there:
• You now have the option to include or exclude the effects of diffraction in the calculation of image sharpness.
• The analog distance scale and the numerical distance readouts are now nicely integrated for a more interactive feel.
• Distance units are changed directly on the main screen by tapping the m / ft button.
• Labels can be hidden, for a cleaner interface.
• Several info (help) buttons have been added.
And there are lots of little improvements.
Enjoy! If you like this free app, wait till you check out the "pro" version, TrueDoF-Pro!

Oh, and there's a new icon, and the file size is much smaller.

iOS 7 compatibility.
The focal length selection wheel no longer free rotates after you stop pushing it.
Focal lengths to 1200 mm are now included.

Added a link to FocusStacker, a new app for landscape and architectural photography - the first ever tool that determines what shots to take (how many, what aperture, what focus distances) to achieve predictable, high-quality results when using the focus stacking technique. Use its suggested settings to produce astonishing sharp images, down to the very limits of what your sensor can achieve, across huge depth of field.
Added a link to several articles covering depth of field, diffraction, focus stacking, etc.
Longer sliders (on 4 inch screen) make for easier and more precise input.
The sensor width slider now snaps to nearest integer value.
Please remember that, as a free app, TrueDoF-Intro is not designed to be full-featured but, rather, is meant to give a feel for the approach taken in the “pro” version. For a very much more capable and versatile app, check out TrueDoF-Pro. You may also like its sister apps, OptimumCS-Pro and FocusStacker.

Added a link to an online article on best practice in working with depth of field.
Selecting focal lengths has been made easier and faster through the removal of all unnecessary focal lengths from the selector wheel. Now, focal lengths above 100 mm are in multiples of 5 mm (those above 200 mm remain in multiples of 10 mm).
