## Most critical reviews (5 lowest-rated)

### 3/5 — Works well enough

*2020-07-14*

It would definitely get 5 stars if it went up to multiple stops instead of just 3/4. I lith print and sometimes I need to add up to 4-5 stops of exposure and it would be much simpler to use this instead of figuring it out in my head and calculator.

### 3/5 — Works well for darkroom printing

*2015-03-03*

Some suggestions for 5 stars would be to display a full stop to 2-3 stops higher as well in the same increments. It would be much more helpful then, rather than having to adjust the time manually to see higher stops. Otherwise though great app!

### 4/5 — Darkroom Test Print

*2026-07-25*

It would be helpful if the app calculated the incremental times needed for test strip, starting with base time at -3/4th stop.

### 4/5 — A great start

*2024-01-07*

This is an easy to use app and a great tool, unfortunately you can only get calculations for +/- 3/4 of a stop. This would be a 5 start app if it could calculate in variations of 1/4 or 1/2 stops up to 2 or 3 stops of adjustment.

### 5/5 — Must have for all darkroom fanatics!

*2014-04-14*

What a genius app, at last a clever & effective tool that saves time & consistency with your prints. Def 5 stars!
