Groutr: Grout Color Visualizer1.2.8 - App Store

Choosing the right grout color can make or break your design. Groutr lets you see how any grout shade - or even multiple shades - will look on your own tiles and mosaics before you commit.

Take a photo of your project, and Groutr automatically detects the grout lines. From there, you can:

- Try any color: pick a custom shade or colors from real grout brands
- Compare side-by-side: preview up to 4 colors at once
- Visualize multi-color grout: paint or recolor lines individually for creative designs
- Edit with precision: erase or redraw to refine the detected grout lines
- Pick colors from your image to match grout samples or tile colors
- Simulate grout on all tile types: mosaics, ceramic, hex, pebble pavers, stained glass, and more. If it needs grout, Groutr can visualize it.

Whether you’re planning a bathroom remodel, designing a kitchen backsplash, or finishing a mosaic artwork, Groutr uses your own images to help you explore options, avoid costly mistakes, and design with confidence.
