### 1/5 — Unusable

*2026-01-11, version 2.0.4*

I paid for sub for year and now it won’t open.

### 5/5 — Best app

*2025-11-25, version 2.0.4*

I think this is so helpful

### 5/5 — Very useful, simple design

*2025-10-27, version 2.0.4*

This is very helpful when working out a painting and a subject

### 5/5 — Excellent little tool

*2025-03-23, version 2.0.4*

I’m a landscape painter, and this is an excellent little tool to see values in reference photos. 99 cents well spent. Save the value rendering back to your camera roll, and compare side by sides. Yes, there are other apps with more features, but they’re either full of ads or charge by the month. This does what I need.

### 3/5 — Could be better

*2025-01-06, version 2.0.4*

I needed ability to see five values to match five-step shadows to highlights distinctions so went with something else.

### 5/5 — Excellent tool for artists

*2024-11-23, version 2.0.4*

Does exactly what I need without unnecessary complications.

### 2/5 — Details of in app purchases

*2024-10-29, version 2.0.4*

This looks like an interesting and useful app, but there is no indication of the price of in app purchases until you try to use a feature. Even then, there is no indication of the duration of that purchase. Is 99 cents for one photo?  All photos?  A week?  Forever?  Does it include the contour lines feature which I think I deduced from the description?  Lack of info makes me hesitant to buy or use. I know the first buy in is very small, but it’s a blind one. Info up front, please.

### 3/5 — Interesting art tool

*2024-10-09, version 2.0.4*

Looking for an app that enables me to look at my work in gray scale to ensure balance of composition.  This was ok but a little bit of fiddling around required.
I really need an app that l can click a button and change colour to grayscale.  This is not it!!

### 5/5 — Great little tool for artists

*2024-09-17, version 2.0.4*

I was looking for an app that would help me do value studies; this one is easy to use, effective, and definitely worth the dollar to buy. FYI the free version allows you to take and save photos in greyscale; the paid version adds the ability to do that with photos from your collection.

### 5/5 — Great app for painting!

*2024-04-02, version 2.0.4*

I just got this app and find that it’s super user friendly and helps me so much with my portraits. This is a great app at a great price!

## Version history (last 5 releases)

### 2.0.4 — 2018-05-14

This app has been updated by Apple to display the Apple Watch app icon.

Photo saving failure was showing an unhelpful "Data unavailable" error when the user didn't grant the app access to the Photo Library.
Now the app will present a detailed message about how to enable the required permissions to be able to save photos.

### 2.0.3 — 2018-04-17

For the 2-level filter there is now a slider that allows to adjust the threshold between black & white. 
So now you can apply a different threshold depending on the photo brightness.

### 2.0.2 — 2018-03-21

Quality improvements

### 2.0.1 — 2018-03-13

Ability to save to the Photo Library a converted to grayscale photo

### 2.0.0 — 2018-03-08

Welcome to version 2.0!

The main feature of this release is a grayscale filter selection. 
There are four filters available: 2-Level (black & white), 3-Level, 4-Level and Continuum (continuous grayscale spectrum) filter.

Please also note that the color/grayscale mode switch is now provided as a double-tap on the screen instead of using a button.

And lastly, this version brings huge performance improvements of the camera view that significantly reduce the battery consumption.
