Overgrid vs GridyPrintX

Add a grid to any reference photo. Transfer proportions to canvas with confidence. Import from your gallery or shoot with your camera. Set rows, columns, line weight. Done. Match your canvas first. Crop the reference to your canvas ratio, then enter your real dimensions. 16x20, 12x12, whatever you are working on. Every square lines up when you transfer. No guesswork, no wasted paint. Customize everything. Grid color, opacity, thickness, diagonals for composition, numbering to track your squares. Make the grid work the way you work. Adaptive contrast reads your image and picks grid colors that stay visible on any background. Dark lines on light areas. Light lines on dark. You never lose the grid. Value study breaks the image into tonal levels so you can plan light and shadow before you start. Temperature overlay maps warm and cool zones across the composition. Save setups as templates. One tap to apply your favorite configuration to any new project. Export at full resolution, up to 4096px, for printing or reference at any size. Free includes three projects, basic grid, and 1024px export. Full access is a one-time purchase. Not a subscription. No account. No cloud. No ads. Your images never leave your device.
