GridPainter is the premium application to use compose your next masterpiece. It lets you quickly and easily place a grid onto an image for the purpose of using the grid technique of drawing and painting, the same method even Leonardo da Vinci used in his work.

With the portability of our devices and access to thousands of images at our fingertips, more artists than ever are using them as a reference for drawings.

With GridPainter, the process of drawing accurately from your device is easier than ever. Simply select the photo you wish from your photo library or using the "Open In" functionality in Messages or email, and the app will scale your image and place the "thirds" style grid over the top.

From the toolbar on top you will find easy to use controls.

-Customize your canvas size or shape it to the Golden Rule.

-Customize your grid pattern from several different styles.


And new for version 2.0 we integrated some functions from our sister application NotanIzer so now you can

-Look at you image in color, gray scale, Notan, or 3 Level Notan

Everything is saved and you can work with your image in the app, or using the share menu, print, email, or export it to your photo library.

To create a drawing from the photo, simply draw a grid of the same proportions onto a piece of paper as your selected final project size and grid size.

From there you can easily transfer the image by drawing whats in each square, letting the grid take care of the proper scaling and framing within your picture.

Great for when you need to draw a large drawing from a small reference photo, or for drawing complicated imagery.

-Select an image from your camera roll , import, or take a photo directly from the app
-Choose final image size
-Place a grid over the image
-Change the grid size
-Change the grid color for best visibility over the image
-Automatically chooses the aspect ratio or use Golden Ratio
-Scale and move your image to fit exactly where you want

Truly an excellent artist’s tool

Plainly said, this app works great for both cropping and placing grids on photos. And then, there’s much more! It’s incredible at creating notan, and various multiple level grayscale versions of my images. Thanks guys for creating your remarkable artist’s tool. It has worked seamlessly for the six months or so since purchase.

Not 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.

Does 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.

Developer Response ,

The release of IOS 11 unfortunately broke our app. We are fortunate that we have some great users who emailed us and worked with us to correct the issues. We also we able to find a better way to handle some memory issues and now it’s runs smooth and fast.
