## Most critical reviews (6 lowest-rated)

### 1/5 — Awful.

*2013-04-20, version 1.5*

It took longer for me to download this app than it did to decide to delete it. Keep that $4 and get yourself a taco.

### 2/5 — Works in a broad sense

*2012-03-07, version 1.4*

But not fine enough for portrait work.  I want 6" at 10' not 4'!  Would be nice to work back from f/stop also.

### 4/5 — Handy but needs LF values.

*2011-02-24, version 1.1*

Very nice and easy to use.  I love the extension from the exposure to the print.  Unfortunately, it doesn't support large format photography.

### 5/5 — Nice

*2013-02-18, version 1.5*

Nice

### 5/5 — Pro

*2012-02-12, version 1.3*

Just great.

### 5/5 — Very good!

*2011-03-28, version 1.1*

Takes into account diffraction. Neat interface. Works well.
