Read full description

Costra tells you exactly what to buy for your renovation — and how much of it. Pick a room, answer six short steps, and get a complete, layer-by-layer bill of materials: primer, plaster, putty, paint, tile adhesive, screed and more — each with the exact quantity for your walls, floor and ceiling. NO SIGN-UP NEEDED Calculate and view full estimates as a guest. Create a free account only if you want to save them. HOW IT WORKS 1. Room — choose the room type and enter its dimensions 2. Condition — describe wall evenness and floor screed, and watch the estimated material weight update live 3. Walls, floor, ceiling — pick your finishes: paint, wallpaper, tile, laminate and more 4. Result — a structured materials list, grouped by surface and layer SMART WHERE IT MATTERS • Quantities follow professional consumption rates and your room's real geometry — doors, windows, wet zones • Every line shows the right unit: kilograms, liters, square meters, rolls, pieces • Tap any material for a hint explaining what it's for • Diagrams show how the layers stack up SAVE AND ORGANIZE (optional, free) • Save estimates to your account and reopen them anytime • Group estimates into projects — an apartment, a house, a client job • Duplicate an estimate and tweak it for the next room IN YOUR LANGUAGE Fully bilingual English/Russian with an instant toggle. Costra is free, with no ads. Your data stays yours — you can delete your account and everything in it at any time, right in the app.
