A mobile app that allows HSI Installaties technicians to instantly link photos to projects, blocks, and house numbers. Making handover documentation fast, accurate, and hassle-free.

React Native, Go
Mobile app
HSI Installaties installs underfloor heating in new homes. Upon completion, they are required by the Waarborgwet to document their work with photos. This was previously done via WhatsApp, which led to lots of manual work, confusion, and administrative delays.
Our Solution
We built a mobile app that allows technicians to view projects and directly upload photos linked to specific house or block numbers. The app is connected to the central project overview and ensures all documentation is instantly stored in the right place. No more hassle or searching afterward.
This way, every handover is documented quickly and correctly, without extra administrative burden on the team.
Key Features:
- Access to current projects, house numbers, and blocks
- Take photos and link them directly to the right property
- Automatic storage of documentation in a central location
- User-friendly for on-site technicians
- No more WhatsApp, photo albums, or manual uploads
The Result
Handover documentation is now smooth and structured. Staff save time, errors are eliminated, and all records are instantly in the right place. What was once messy and time-consuming is now fully automated and organized.
