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.

Verdict

The call

The clearest difference is review sentiment: ClayLab at 91% against Groutr's 44%. ClayLab also leads on ads (none vs shown) and rating (4.6 vs 4.3). Groutr's advantage is update cadence (every 3 weeks vs every 2 months) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.
