## Most critical reviews (5 lowest-rated)

### 1/5 — Confusing UI, doesn't cover micro 4/3

*2019-08-11*

Title says it all. The UI is very confusing and the app doesn't cover micro 4/3 websites.

### 1/5 — Will not calculate with payment...

*2019-01-30*

Can’t evaluate how it calculates DoF as it requires a paid upgrade to test. Happy to pay, but not without testing.

### 1/5 — No camera

*2017-04-17*

Installed but can't see any option to take photo or to edit a photo. Deleted

### 1/5 — Money grabber!

*2016-03-05*

Opened the app, tapped on calculator and get a buy pro app banner that also closes the calculator! Deleted this waist of space and time, absolute rubbish !!!

### 2/5 — Nice Try, for sure, but found this very difficult to use

*2017-07-12*

This seemed almost impossible to practically use.  I'm a bit of an armature photographer, so this might be intended for a deeper background.  I have been an avid photographer for ~45yrs (so I'm not new to this), and am an engineer by training.  So I'm also not daunted by the concepts, math, or technologies.  I also found the app a bit buggy - would periodically hang up.  I also found it very difficult to use on an iPhone due to size (for which I was forewarned), but have also installed it onto an iPad with no better results.  Great try, for sure, but in a practical sense I didn't find it was going to be useful.
