ValueViewer App Reviews

Ive used this app for a couple of weeks and it works perfectly!!! I Love it! Ive used several other apps in the past, one after another to try to achieve what this app does in a few seconds. Simple, concise, user friendly. Absolutely worth every penny. I use it in the field and in my studio.

Every time I try to access previously-taken photos (on my iPod Touch), the app crashes.

The controls are in the middle of the screen. When the controls are tapped, they either freeze on the screen and the entire app is frozen, or they disappear entirely. The app worked perfectly on my iPhone5 before the last two upgrades. Is there a way for me to return to the app as it was before the last two upgrades?

Grids totally dont work with iPhone 5. This could be a really useful tool. So designers whats the story????

Worked fine 5 times on my IPhone 5 then when I tapped the controls, the app totally froze up. It was great while it worked. Wish the problem could be fixed. Very disappointed.

I have down loaded the app twice and each time I have tried to use it the tool bar freezes. Have contacted the developer but no reply.

Love love love this app except for one BIG thing - please please please ad numerical proportions. How can we translate to paper if there are no numbers? JUST A MUST! Then you will have a FAB APP!

Spent $4.99 last night for app. Saw controls for a 1/2 a moment, when hit one of bottom arrows, controls disappeared altogether. Can pinch, expand, lock, rotate image, but otherwise frozen. Impossible not to feel ripped off. App support claims bugs of controls fixed. Nope

I used this first on my iPod touch and loved it. Then, I got an iPhone 5. It wont work on the iPhone 5, so I tried my iPod touch and it doesnt work there anymore either. This was a great app several months ago. Please fix it.

I was doubtful about this app. since there were so many negative reviews, however, I find it to be very useful as an artist. I downloaded this on an iPhone4S and it works very simply. Once you click on the Value Viewer App, select the camera icon, take a photo of your subject, use the arrows indicated to view it in color, grayscale, notan (black and white) or value levels. You can increase and decrease the contrast in notan and value levels with the Alpha and Omega symbols. The photo can also be cropped. Use the arrows again to select the grid format you want. At this point the photo can be saved into your own photo library. Voila! - I can bring it up again if I want to work in my own studio. I can also email the photo to myself from my stored photos on the phone, and print it out in a large format if need be.

Should have read reviews & saved my money! It worked a few times on iPone5 then completely froze! No updates available either. Disappointed!

No controls after using it 3 times. I should have read reviews. Why have this in the App Store with such a poor record?

Works great. So very useful! Really helps me see values better. Even has a Notan view, plus Levels which you can adjust. Very handy to be able to go back and forth from b/w to color. Just so many things that are useful to painters.

Great concept and app. Please fix it so it stops freezing once you get to the grid choices. If you goose to grid, you cant go back wards, clear screen nor get to home page. You have to delete app and reload, losing all your saved data.

I use this all the time on my iPad. No problems with freezing, etc. as reported by other reviewers. It’s very helpful for the initial drawing - being able to choose the aspect ratio of the painting, and then to put grid lines over it.

Great idea for a tool to reference your photos for painting as you can change your photo to notan, or greyscale. Never able to get the grid to work. Also the ribbon will move the controls off the screen and there is no way to bring them back. Please fix this!

I heard about this app from reading Jo Mackenzie’s book Three-Step Watercolors. I had been looking for an app that would help me view the NOTAN patterns in my photo references before I started a new art piece. After getting tired of squinting all the time to look at my photo reference to discern the NOTAN patterns, I was grateful to discover the existence of this app. I like that I am able to get both the gray-scale and the NOTAN views of any of the photos I have in either my iPhone or the iPad. The app works best for my aging eyes in the iPad because of its larger screen.

This wonderful app has become my daily painting buddy...an indispensable assistant. User friendly, functional, well designed. How did I paint without it? I heartily recommend this app.

Great app that works smoothly with a nice interface. It has helpful functions for visualizing plein air painting. Please, for the grids, I would say add a thirds grid. That would make the app more perfect, but it is 5 stars as is.

Love Love this app! Can I get it on my macbook pro?
