The best grid app for artists in 2026 is Overgrid. It puts an adjustable grid on any reference photo, scales it to your real canvas, and adds what painting needs: a value study, a warm and cool temperature map, and a grid color that stays visible on any image. It runs on iPhone, iPad, Mac, and Android, with no ads and a one-time upgrade.

Below, seven grid drawing apps compared honestly, with what each does well. The grid method itself is old and proven. If you want the full technique, history, and how to scale a grid to a larger canvas, read the complete guide to the grid method. This article is about the apps. We first published it in June 2026 and rechecked every App Store and Google Play listing in October 2026: price, ads, subscriptions, platforms, ratings, features, and last update. Prices are US store prices and vary by country.

The shape of the category

Grid apps split into three groups, and knowing which one you are looking at saves you money and frustration.

The free apps are the most visible, and most of them are paid for with ads, subscriptions, or both. The friction lives in the experience rather than the price tag, and it has spread: DrawinGrid, long the ad-free favorite, now carries ads too. Then there is a small tier of fair one-time apps that you buy once and own: Overgrid, Grid Painter, and CopyIt. And there are AR projectors, which trace rather than grid and tend to run on subscriptions.

Read enough App Store reviews and artists ask for the same things over and over: a fair one-time price, no ads, no project caps, work that stays private and offline, reliability, and ideally tools that help with the painting itself, not just lines on a photo. That list is the reason Overgrid leads here, and it is the lens for the rest of the apps.

1. Overgrid, the best grid app overall

Overgrid is a grid overlay app built for painters. You pick an image, choose your grid, and it appears in seconds. You set rows, columns, line weight, opacity, and color, and switch between full lines, dots, or crosses at the intersections. You can add diagonals for composition analysis and numbering to track your squares, crop the reference to your canvas ratio, including a custom ratio, and rotate or flip it before you grid, so the transfer is not distorted. You can duplicate a project to try a different grid on the same photo, and the screen stays awake while you draw. That covers the core, and it covers it well.

What sets Overgrid apart is the temperature overlay, which maps the warm and cool zones across your composition. No other app in this roundup offers one. Color temperature is one of the hardest things to see in a reference and one of the easiest ways to flatten a painting if you get it wrong, and Overgrid puts it on screen. On top of that, the value study overlay reduces the reference to a chosen number of tonal levels, from two for a notan up to eight, so you can plan light and shadow before you commit paint (here is how many values a study actually needs). The adaptive grid color reads your image and picks line colors that stay visible whether the photo is a dark forest or a bright sky. And Canvas size mode lets you type in your real canvas dimensions, in centimeters or inches, and get a grid scaled to that surface, large enough for a mural wall.

The free version is a real tool, not a teaser: a working grid with six preset colors, up to three projects, and smaller saved images, with no watermark. Premium adds unlimited projects, any grid color, the adaptive grid color, Canvas size mode, the value study and temperature overlays, templates you save and reapply in one tap, and full-resolution saves for printing at large sizes. Premium is a single one-time purchase. The App Store listing states it plainly: “Full access is a one-time purchase. Not a subscription.” No account, no cloud, no ads. Your images stay on your device.

Platforms: iPhone, iPad, Mac (App Store) and Android (Google Play). Price: Free, with a one-time premium upgrade. No subscription. Best for: Painters and illustrators who want grid, value, and temperature analysis in one app they buy once, on every device on the same store account. The honest catch: Overgrid is young, with only a handful of App Store ratings so far, not years of reviews. The analysis tools also live behind the premium upgrade. If all you ever need is a plain grid, the free tier may be all you use.

2. Grid Painter, the low-cost runner-up

Grid Painter by bigpantsgroup is a genuinely good app and the cheapest paid option here. It overlays an adjustable grid on your reference and goes beyond plain squares, with several grid styles, the Golden Ratio, and standard or custom canvas sizes. It borrows the engine of its sister app NotanIzer, so you can view the reference in color, grayscale, notan, three levels, or four levels, exactly the kind of tonal planning a painter wants. It crops, saves projects, prints, and runs natively on Mac. One reviewer summed up the appeal: “elegantly simple to use and does everything I need it to do.”

It holds a 4.82 rating across 397 App Store ratings, the highest average of any app here with a long review history, and it costs $2.99 once, with no in-app purchases. What it does not do: there is no color temperature overlay and no Android version. And it has not been updated since November 2021. It still works, but nobody is improving it.

Platforms: iPhone, iPad, Mac (App Store). No Android. Price: $2.99 one-time. No subscription. Best for: Apple users who want value studies and golden-ratio grids at the lowest possible price. The honest catch: No temperature overlay, no Android, and no updates in nearly five years.

3. CopyIt, the feature-heavy veteran

CopyIt The Grid Drawing Method by Nigel Green has been on the App Store since 2010, longer than any app here, and it is still actively developed, with its last update in April 2026. Its listing now opens with a line many artists will like: “CopyIt has returned to a simple one-time purchase.”

It is dense with tools: six grid types with custom rows and columns, a digital ruler, perspective lines, a crosshair, zoom up to twenty times, a Pencil Sketch filter, an onion-skin overlay, greyscale filters with a Tonal Strip for block value studies, and TubeMatch and MixMap for matching paint and pencil colors. A second reference layer lets you fade between the photo and a picture of your work in progress to check accuracy. It holds a 4.68 rating across 297 ratings.

Platforms: iPhone, iPad, and Macs with Apple silicon, where it runs as the iPad app (App Store). No Android. Price: $19.99 one-time. No subscription. Best for: Artists and art teachers who want the deepest toolbox on Apple devices and do not mind paying more for it. The honest catch: The highest price here, a busy interface that comes with that many tools, no temperature overlay, and no Android.

DrawinGrid by ButterflyRay is the free grid app artists recommend to each other most, and the numbers show it: a 4.74 rating across more than 5,000 App Store ratings, and over a million installs on Google Play, where it is listed as Drawing Grid and rated 4.8. It is actively maintained, with an update in September 2026.

It has also changed. DrawinGrid was long the ad-free free option, and it now shows ads: Google Play labels it “Contains ads,” and the App Store lists a Remove Ads purchase at $10.00 alongside Pro options. The app has grown past the grid into AR tracing, on-screen tracing, project time tracking, cloud sync, AI title suggestions, and a public gallery, and the account-based features are where the developer’s site points its “optional in-app purchases and subscriptions.” The grid itself remains free. It is still not a painting workbench: no value study, no temperature map, no Mac app.

Platforms: iPhone, iPad (App Store) and Android (Google Play). Price: Free, with ads. Remove Ads and Pro options are paid. Best for: Anyone who wants a proven free grid with tracing tools and does not mind ads. The honest catch: Ads unless you pay, no analysis tools, and a feature set drifting toward accounts and subscriptions.

5. Grid # - Add grid on image, the simple utility

Grid # - Add grid on image is the simplest entry here and one of the most rated, with 4.61 across more than 10,000 App Store ratings. It puts a rectangle or square grid on a photo, with any RGB line color, transparency, line width from 1 to 20, and color picking from the image. If you just want lines over a reference to start drawing, it is quick.

Some options are paid: a third grid layer, movable and rotatable grids, and one square grid type are marked as pro features in its own description, unlocked by a single $3.99 purchase named “More features & Remove Ads,” and its privacy label lists third-party advertising. Its last update was in April 2024. There is no value or temperature analysis, and it is a general photo-grid utility rather than something designed around how painters think.

Platforms: iPhone, iPad (App Store). No Android. Price: Free with ads, $3.99 one-time upgrade. Best for: Anyone who wants a grid on a photo immediately, with no extra features. The honest catch: Ads in the free version, minimal art-specific features, and no update since April 2024.

6. GridArt, high visibility with a monetization problem

GridArt is one of the most visible grid apps, especially on Android, where it has passed a million installs and holds a 4.3 rating across about 14,000 ratings. The grid tooling is capable and actively updated: diagonals, a square grid, labeled rows and columns, a measurement-based setup in millimeters, centimeters, or inches, a sketch filter, black and white conversion, crop to aspect ratios, and, since late 2025, AR drawing through the camera. On the App Store it holds a 4.54 rating across 218 ratings.

The recurring complaint, in the app’s own App Store reviews, is the monetization. The app is free to download, both stores label it as containing ads, and the App Store lists a GridArt Weekly Premium at $3.99 and a Monthly Premium at $12.99. Reviewers describe ads “constantly displayed” and uninstalling over them. None of this is a knock on the grid itself, which works. It is a fair warning about the experience around it.

Platforms: iPhone, iPad (App Store) and Android (Google Play). Price: Free, with ads and a weekly or monthly subscription to unlock features. Best for: Android users who want a feature-rich grid and do not mind ads or a subscription. The honest catch: Ad load and subscription gating that reviewers consistently flag.

7. Da Vinci Eye, the AR alternative

Da Vinci Eye is not a grid app, and we include it because artists searching for grid apps are often really asking how to transfer an image. Da Vinci Eye is an augmented-reality projector, a digital camera lucida: it overlays your reference through the camera onto your paper or canvas so you can trace it, and it can split the image into layers by value to show where the darks and lights go. It is the most-reviewed app in this space, with a 4.55 rating across nearly 12,000 App Store ratings, and it is genuinely good at projection.

It runs on subscriptions. The App Store lists monthly plans from $1.99 to $9.99 and yearly plans from $9.99 to $49.99, so check what each tier includes before committing. The cost is the structure more than the price: you keep paying for as long as you use it, and it renews until you cancel. If you would rather project and trace than grid by eye, it is the obvious choice. Just go in knowing how the billing works.

Platforms: iPhone, iPad (App Store), plus Android and Apple Vision Pro according to the developer’s site. Price: Free to download, with monthly and yearly subscriptions. Best for: Muralists and anyone who would rather trace a projected image than draw from a grid. The honest catch: It is a projector, not a grid, and it runs on a subscription that renews until you cancel.

A new grid app worth watching

Photorealism: Grid Method, designed by the photorealist Dylan Eakin, launched in September 2026. It adds a custom grid, separates the reference into layers, tracks how many squares you have finished, and compares your drawing against the photo. Early ratings are high, 4.95 across 79, and the free version shows ads, with Remove Ads purchases. It is too new to rank, but realism artists working in graphite should keep an eye on it.

How to choose a grid app

Start with how you want to pay. A grid is a finished tool. It does not need a server, an account, or monthly updates to keep working, so a subscription is value flowing the wrong direction. Overgrid, Grid Painter, and CopyIt are one-time purchases. GridArt and Da Vinci Eye charge on subscriptions. Over the years you will own a tool this simple, that difference adds up.

Then ask what you are doing. If you draw in graphite, proportion is the whole problem and a plain grid solves it, and several apps do that for free, each paying for it in a different way. If you paint, value and color come right after proportion, so an app with analysis tools earns its place. That narrows it to Overgrid, which has value, temperature, and adaptive grid color, and Grid Painter and CopyIt, which have value views. If temperature mapping matters to your work, only Overgrid has it. If you are on Android, that rules out Grid Painter and CopyIt, which are Apple-only.

Finally, weigh platforms and privacy. If you move between an iPad on the couch, a Mac at the desk, and an Android phone in the field, Overgrid is the only app here with its own apps for all four. If you already draw in Procreate, its built-in grid has a gap worth knowing about, explained in why Procreate’s grid does not work on reference photos. And if you would rather keep your reference photos off a server entirely, look for apps that run offline with no account, Overgrid among them.

The bottom line

For most artists in 2026, Overgrid is the best grid app: a clean grid scaled to your real canvas, painting analysis including a temperature overlay no other app here offers, four platforms, no ads, and a one-time purchase instead of a subscription. Grid Painter is the low-cost runner-up on Apple devices, with value views, though it has not been updated since 2021. CopyIt is the deepest toolbox, one-time at a higher price. DrawinGrid is the most popular free grid, now with ads. Grid # - Add grid on image is the fast simple utility. GridArt is feature-rich if you tolerate ads and a subscription. Da Vinci Eye is the pick if you want to project and trace instead.

Start with the free grid in Overgrid. If you paint and you want the value study, temperature, and canvas size tools, the upgrade is a one-time purchase. Overgrid is available on iPhone, iPad, and Mac and on Android.
