About
Roomdar turns your iPhone into a measuring tool. Walk through a room once – Roomdar captures the geometry, doors and windows, and turns it into a quantity takeoff you can hand to a client.
QUANTITIES, NOT JUST A MESH
Other apps give you a 3D model. Roomdar gives you numbers: wall areas, ceiling areas, reveals, skirting and drywall – structured along German VOB/C trade rules. Deductions and openings are itemised line by line, each with the calculation behind it.
DIFFICULT ROOMS TOO
Sloped ceilings, free-standing columns and chimneys are detected and handled properly: a column's footprint is deducted from the floor, its lateral surface added to the wall area. With sloped ceilings, the remaining flat ceiling is reported instead of being counted twice.
HONEST ABOUT UNCERTAINTY
Where the capture was unreliable – large corner gaps, implausible areas – Roomdar says so in the takeoff instead of presenting a wrong number as certain.
EXPORT THAT GOES SOMEWHERE
- PDF takeoff to share
- CSV for spreadsheets
- GAEB X83 and DA11 for estimating software
- USDZ model for clients and planning
YOUR DATA STAYS YOURS
Roomdar works fully offline. No tracking, no advertising identifiers, no analytics, no third-party SDKs. If you want to sync, use Roomdar Cloud – operated by Marco Strothmann, strothmann.dev. Files are stored AES-256 encrypted, every request is signed, and nothing is passed on to third parties. There is nothing to set up and no server to run. Projects are grouped by room and versioned – rescanning replaces the current version without destroying the old one.
WHO IT IS FOR
Painters, drywall and flooring contractors, electricians, surveyors, property managers, architects – anyone who measures rooms regularly.
REQUIREMENTS
Scanning requires a device with a LiDAR sensor: iPhone Pro and Pro Max from iPhone 12 onwards, iPad Pro from 2020. Without LiDAR you can still view models and edit takeoffs.
IMPORTANT
Roomdar produces measurements, not certified construction documents. Verify all dimensions on site before quoting, ordering or building.
SUBSCRIPTION
The core features are free. Pro and Team unlock unlimited projects, GAEB export and cloud sync. Subscriptions renew automatically unless cancelled 24 hours before the period ends. Manage them through your Apple ID.
