Gridline

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. ā 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 ā 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, 8Ć10, 9Ć12, 11Ć14 or 16Ć20 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. ā 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. ā 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.

Verdict
The clearest difference is ads: PaintSteps at none against Gridline's shown. Gridline's advantage is iOS requirement (13.0 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.
