Floor, wall, full room. With grout, waste and a pack count.
Wall and ceiling area × coats = liters, cans, cost.
Rolls with pattern repeat factored in. No store-trip surprises.
Screeds, slabs, foundations. m³, 25 kg bags, cost.
U-value, WT 2021 compliance check, estimated yearly savings.
m² and linear meters, glazed porcelain, 3–5 mm grout, U-values to Polish WT 2021. Defaults match what you'll find in European DIY stores — no inch-to-mm conversions slowing you down.
One static banner at the bottom, that's it. No interstitials, no popups jumping between entering a dimension and reading the result. A one-time $3.99 purchase removes the banner for life.
Bundle calculations into projects (Bathroom, Kitchen, Living Room). The app aggregates materials across calculators and exports a PDF to send to a contractor or take to the store.
Yes. All calculations run locally — no measurement data leaves your device. Internet is only needed for the bottom banner ad and the one-time in-app purchase.
Yes. A one-time $3.99 purchase removes the banner for life. No subscription, no auto-renewal — works after a reinstall too.
No. Pay once, keep it forever. A subscription doesn't fit the one-off nature of a renovation.
Tiles (floor / wall / room modes), paint, wallpaper, concrete and insulation. Each comes with Polish-market defaults and is cross-validated against established renovation calculators.
Yes — in project mode. An aggregated material list across all calculators, in a single PDF you can take to the store or send to a contractor.
iPhone with iOS 16 or later, Android 7.0 (API 24) or later. The app is small and runs fine on older hardware.
Polish and English. Czech, Slovak and German are planned as those markets open.
λ values come from manufacturer datasheets (EPS 70 = 0.040, mineral rock wool = 0.035, PIR = 0.022). Polish WT 2021 requires external walls ≤ 0.20 W/m²K, roofs ≤ 0.15, ground floors ≤ 0.30.
