Holzbau2.0: Carpenter Tool

Timber Construction App – Your digital companion for carpenters and builders

The Timber Construction App is the ideal tool for anyone who wants to plan roof structures, calculate rafters and purlins, or precisely visualize projects. It is aimed at carpenters, construction professionals, architects, and dedicated DIY enthusiasts who want to better understand and control their building projects.

Features at a glance:

Project management: Create your own projects, save all inputs in a local database, and load them again at any time. This way, you always keep track of multiple building projects simultaneously.

Rafter and purlin calculation: Define all relevant dimensions such as building width, rafter height, purlin distances, and roof pitch. The app automatically calculates axis dimensions, number of rafters, and purlin lengths – including consideration of overhangs.

Roof pitch & angles: Measure angles directly with the camera or calculate them from entered values. The app supports right-angled and irregular triangles, checks plausibility, and displays warnings for invalid inputs.

Tile and batten layout: Plan the division of roof tiles on rafters. The app automatically calculates minimum and maximum cover lengths, eaves overhangs, and tile rows.

Hip and valley rafters: Calculate hip rafters, valley rafters, and their bevel cuts or backing dimensions. All calculations are based on practical formulas, allowing you to quickly verify your construction.

Timber cross-sections & supports: Enter rafter and purlin cross-sections, knee wall heights, collar beams, and ridge beams – the app visualizes support points and helps with dimensioning.

Visualization: Interactive sketches display the roof structure proportionally and to scale. You can directly follow rafters, purlins, and roof overhangs.

Scale calculator: Quickly and easily calculate scales between plan and real dimensions or between metric and imperial units.

Notes & projects: Add notes to your projects, save all calculations locally in the database, and keep the complete project history.

Advantages:

Local storage: All project and input data remain on your device – no cloud and no transfer to third parties.

Practical: All calculations are based on real building conditions.

User-friendly: Intuitive input forms and interactive sketches simplify planning.

Flexible: Supports various roof types, from simple gable roofs to hip roofs with hip and valley rafters.

Privacy & security:

The app does not collect personal data.

Camera access is used only for angle measurement.

Storage access is used exclusively for saving and loading projects or PDFs locally.

Conclusion:
The Timber Construction App combines precise calculations, clear visualizations, and practical tools for anyone who wants to understand and plan roof structures. It is an indispensable companion for carpenters, builders, and DIY enthusiasts – now with full project management and a local database.
