Drawing Grid Maker vs Gridline

GridValue turns any photo into a drawing guide. Add a grid to your reference, match it on paper or canvas, and draw square by square. HOW IT WORKS • Choose a photo or try the built-in sample. • Pick your paper or canvas size and a grid such as 6 × 8. GridValue shows the exact size of every square in cm or inches. • Zoom into one square at a time, lock the view, and draw without losing your place. • Export a print-ready guide as PDF, PNG or JPG and see the printed cell sizes before you print. MADE FOR DRAWING • Coordinate labels (A–F, 1–8) so you always know which square you are on. • Grayscale mode to judge values without colour distraction. • Adjustable line colour and opacity that stay thin at any zoom. • Projects save automatically, so you can pick up where you left off. GRIDVALUE PRO • High-resolution 300 DPI exports without a watermark. • Unlimited saved projects. • Print at the right size: A4, A3 or Letter with true cell measurements. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID account. Manage or cancel anytime in Settings.

Put a grid over any reference photo and check its values on the same screen. Gridline is a drawing grid for painters, illustrators and art students who work from reference photos. Import a picture, set up the grid, switch to grayscale or a notan when you need to judge values, and paint with your phone or iPad beside the easel. ■ Free • Import from your photo library or take a new photo • Square or rectangular cells, with any number of columns and rows • Diagonals, cell numbers, line color and line thickness • Grayscale view, a 2-tone notan, and mirror • Paint mode: the tools disappear, touches are ignored and the screen stays awake, so the device can stand by your easel. Long-press to leave • Unlimited projects, each one reopening with the settings you left ■ Gridline Pro (one-time purchase) • Notan in 3, 4 or 5 tones: drag the split points on the value scale and simplify the small details • Fit to canvas: crop to A4, 8×10, 9×12, 11×14 or 16×20 in, or square, in portrait or landscape, and see the real cell size in cm or inches • No ads Pro is a single purchase, not a subscription. You can restore it on other devices signed in with the same Apple Account. ■ About ads The free version shows one banner ad at the bottom of the project list. The editor, where you look at your reference, has no ads. ■ Your photos stay on your device Gridline keeps its own copy of each reference inside the app. There is no account or sign-up, and your images are never uploaded.
