Grid Painter 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, the app will scale your image and place a default 2" grid over the top.

From the toolbar select the settings button and decide how big you want your final drawing to be under “canvas size”, change the grid color for a nice contrast, and size of the grid. Keep or change the aspect ratio.

You can also crop the photo if you only want a portion.

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.

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.


Very helpful!

I use this app to place a grid over photos I paint from my iPhone or iPad. It's very easy and intuitive to use! Makes my life much easier! Haven't found anything else in the App Store that works like this one.


What an awesome tool!

Anyone who paints or draws from a source photo on their phone or pad needs this app. No more printing color photos and hand drawing graphs. Zoom in or out. Simplify. Its all in your hand. Love it!
