### 3/5 — Readings unofficial for NIKON D780

*2026-07-31*

The only settings available are for the NIKON D750 and the NIKON D 700. My camera NIKON D780 is not available. I tried to set in for NIKON D7 50 but they are in effect not very accurate. But I must say at least sometime I can vary the differences for usability.

### 5/5 — Clean, efficient, complete

*2026-07-30*

I don’t get why this isn’t better rated, although the brutal ads may be part of it. I discarded it at first because they were so frequent, it seemed like a spammy junk app. After trying all the other DOF apps I reluctantly came back to this one and for some reason got way fewer ads so I could actually test it out.

Wow, what a great interface! Clean, clear, simple. Easy to read big numbers and one-handed operation. Actual 1/3-stop adjustments for aperture, not just a decimal number you have to fiddle with to get right. a usable focus range, that reads out in sensible units. All the info you need and none that you don’t.

This is the one you’re looking for.

### 1/5 — Unusable

*2026-03-09*

Due to the ad logic on the free version it’s unusable.

### 1/5 — Junk now

*2025-12-22*

…Plus the intrusive ads

### 1/5 — Did not have my camera, still charged money

*2024-04-07*

Waste of time

### 5/5 — Great app

*2022-09-15*

It works very well. Easy to use!

### 2/5 — Good but missing latest Sony Camera

*2022-09-12*

Good easy to use app on my iPhone.  However, disappointed to see that the latest Sony a7 iv model is not available… and I already paid the extra $1.99 for the Sony cameras.  To note, the Sony a7 iv started selling in October 2021, so it’s been almost a year!!!
Hope you can add this model soon!  Please!

### 1/5 — This app has two main issues

*2022-03-02*

Hello app makers!

This app has two main issues:

1. Too much data sharing. I value privacy a lot, and there's no reason an app should be entitled to my data. What I do on my phone is 100% my business, not anyone else's. There should absolutely no background non-consensual data sharing within the app. Having it listed on the app's download page is not consent, since it's treated as "normal," and it does not ask confirmation.

2. Hundreds of out in the open purchase buttons within the app. This is just a bad user experience. Do you really think anyone wants to scroll past hundreds of purchase buttons while using an app? Not only is it cluttered, it also makes it more likely that someone would make an accidental purchase that they didn't mean to. That is the last thing a person should have to worry about in an app. When I download an app, the transaction between you and me is over. If you want money, ask for it up front. Don't hide it within the app. If you don't ask for it up front, I will never purchase anything within the app.

Apologies for the strongly worded message. I have seen so much of this online, I have lost patience for it.

### 1/5 — This app pastes from your clipboard

*2021-11-19, version 2.4.7*

Why does this app paste from the clipboard as soon as you open it up? It should be a simple depth of field calculator with sliders and numbers. It doesn’t even have a text field for text entry. 

Perhaps it’s innocuous or accidental or maybe related to ads. But still not cool.

### 1/5 — Save your time

*2021-05-02*

Technically it’s not a scam, but it’s close enough that I’m rounding up.I downloaded this, found my camera (Sony full-frame), the app said I had to pay, so now I’m rating & deleting it and using a different app. Not worth my 2 minutes.
