1. 5/5Perfect

   Ever since Value Viewer went away years ago I’ve been looking for an app for making grids, notan, and value plans of photo references for painting. I’ve downloaded and paid for so many that ended up unusable for various reasons. This works perfectly, is elegantly simple to use and does everything I need it to do. It allows you to adjust value levels, number of values, overlay a grid, etc., and the functions are brilliantly easy to figure out. Thank you so much.

2. 3/5Not ideal

   I was hoping that the custom grid feature would allow for truly customizable grids but it does not. It would be great if the user could combine multiple grids without taking a screenshot in app and applying a second grid over the screenshot image. It would also be nice if it had a feature where the user could select the number of rows and columns instead of merely adjusting the size of the grid squares. It would also be nice if the user could add movable lines to customize it further. The art school I graduated from taught the method of drawing an x through the canvas from opposing corners and then a cross through the center and further refinement by doing the same within the smaller shapes generated which end in rectangles of the same ratio as the canvas. Geometrically this makes more sense than breaking the grid out into squares, especially if using a non standard ratio canvas. It is also easier than carrying around a ruler to measure out squares on the canvas. Overall it was a bit disappointing and I would have been willing to pay more if it were compatible with the way i use grids.

3. 2/5Has annoying bug; disappointing cropping feature

   I decided to purchase this app primarily for the notan and grayscale features (there are free grid apps available) as well as its apparent ability to crop an image to custom sizes. Unfortunately, I quickly discovered a really annoying issue that makes the notan and grayscale feature pretty much worthless to me (and thus the app): for no reason whatsoever, it always rotates any square format photo when either of these filters is applied. Since I work in square format a lot, this is clearly a significant issue. There is no button or anything that I could see that would allow for me to un-rotate the image. The crop feature is also next to useless in that it only allows for absolute values - in inches - instead of ratios, like 1:2 or 3:4, etc. You plug in the size in inches and the crop borders remain fixed; there is no way I can figure out to expand or contract either the image or the crop grid to actually resize the picture. It is not a vector scaled cropping feature, in other words. Which is inexcusable: why would it be necessary to define an image on an iPad with actual inches vs. simple customizable and standard ratios? Answer: it isn’t. I wrote to the developers, waited a week, and heard nothing. Maybe seeing a poor public review will prompt a response and maybe some action to fix the rotation issue and poor cropping feature. At this point, I’d say if you are looking for an app with good functionality in terms of cropping, and especially if you’re ever trying to apply the non-grid features to your square format images, definitely skip this one 🙄.

4. 1/5Does not work

   The crop feature does not work. The page freezes and does not let you crop OR cancel out of it. I have to shut the app down, reopen it and start over. I can use the grid, but I need the cropping feature I paid for. Also, when sending an email to the developers from the app regarding this issue I discovered that the contact page with my composed email also just stayed open after I hit Send. There is no way to know if the email was sent or not. The only choices on the page are to hit Send or Cancel. Hit Send and you get nothing, hit Cancel and it asks if you want to delete your draft - implying that the email did not send. (However I had cc myself and found I had an email in my inbox for every time I had hit send!) Again, the only way to leave this page is to close the app, then open again to get to the main page. Totally frustrating. This app does not do what it claims it can and has been a waste of my time and money.

5. 5/54 Artists who need grids laid on source images

   I haven’t used any other apps for this so it’s not a comparison but it’s nice to have an app where I can lay a custom grid on an image. The performance or interface of touch and adjustments between screen isn’t user friendly but eventually you figure it out. Using over life drawing figure study reference photos to help as training wheels with learning artist’s figure drawing anatomy.
