HDD Assistant is a practical app for horizontal directional drilling (HDD) professionals. Measure ground surface profiles with AR-assisted tools using your phone’s sensors, build bore plans or LWD profiles, and generate professional reports in minutes.
Key features
Bore Planning * Measure terrain profiles between two points (A → B) with AR guidance * Pin key areas during measurement for later use in reports * Draw a proposed bore path directly on the graph (by rod length) * Adjust rod positions and add utilities with a single tap
LWD (Rod-by-rod Profile)
* Create projects with rod length (and optional first rod length) * Enter locator readings rod-by-rod to build the profile * Edit or delete entered rods/stations at any time * Add utilities when needed (distance is calculated from the utility’s center)
Reports
* Export polished PDF and Excel reports for both Bore Planning and LWD * Fill job information and optionally add your company logo * For LWD reports: optionally attach a GPS / Site Map image (manual selection) * Share or save output files in a couple of taps
Cloud Storage
* Projects are stored in the cloud by default and доступны from your linked account * You can disable cloud storage in Settings
Project transfer (.hdda)
* Export any project into a .hdda file and share it * Import .hdda back into the app — the project type is detected automatically and saved in the correct section
