Estimates for illustration. The app uses the same idea with your project data.
🏺 We are a tiny crew of makers and developers who got tired of cracked vases and sticky varnish. We build tools for people who shape clay at the kitchen table.
🎯 Our mission is simple: take the waiting-game anxiety out of air-dry clay so every piece survives from first pinch to final coat.
🧰 Clay Relief Craft gives you drying forecasts, step-by-step projects, a recipe catalog, supply tracking and a project ledger, all in one pocket companion.
🌿 It matters because patience is easier with a plan, and your creative life should stay yours, offline and private.
Shape slowly. Finish beautifully.
