Rembrix: Build & Renovate

Rembrix helps you prepare for building and renovation: calculate materials, plan a room, save calculations by project and put together a shopping list. Construction calculators, store loyalty cards and practical tools are brought together in one app.

📐 BUILDING AND RENOVATION CALCULATIONS

Use 50 calculators for areas and volumes, concrete, masonry, timber, steel, finishing materials and roofing. Enter dimensions and adjust waste allowances, consumption rates and pack sizes. View results and formula explanations to understand how material quantities are calculated.

🏠 IRREGULAR ROOM PLANS

Create a rectangle, an L-shaped or U-shaped room, or draw your own layout on a grid up to 20 × 20 cells. Enter the actual segment dimensions, ceiling height, windows and doors. Calculate floor and wall areas, perimeter and volume, accounting for the openings you specify.

📂 PROJECTS AND SHOPPING LISTS

Keep rooms and saved calculations together by job. Compatible materials are combined in a shopping list with pack quantities rounded up. Enter prices yourself, view totals and mark purchased items. Use a colour or product reference to keep different materials separate.

💳 STORE LOYALTY CARDS

Scan a barcode or QR code with the camera, read one from a photo or enter a number manually. Find a saved card by name and display its enlarged code at checkout. Cards are stored on your device; acceptance of a digital code depends on the store and its equipment.

🧰 TOOLS AND REFERENCE

A spirit level, angle meter, screen ruler with calibration, torch, unit converter and slope calculator help with everyday tasks. Browse timber and steel dimensions and weights, renovation guides and checklists. Tool availability and accuracy depend on your phone's sensors and hardware.

🎨 SETTINGS AND OFFLINE USE

Choose Russian or English and a light or dark theme. Core calculations, projects and saved cards work offline without registration. All features are available without subscriptions or in-app purchases. An ad may appear when the app starts; loading ads requires an internet connection.

📤 EXPORT AND LOCAL DATA

Export a project to PDF, a shopping list to CSV or a JSON backup for later restoration. There is no automatic cloud sync. You can delete local data in settings. Importing a backup replaces the current records, so save anything you want to keep first.

ℹ️ BEFORE YOU START

Results are estimates based on your inputs, selected consumption rates and material properties. Check the manufacturer's specifications and consult a qualified professional for structural decisions. Phone measurements do not replace calibrated construction instruments.
