Matterport is starting to get into mobile (phone, tablet) capture, but they've built their business up on their branded hardware and cloud platform. I didn't try this, but if I was doing this all the time, it seems like it would be essential. These can be used through Bluetooth to enter the measurements directly into the floorplans in MagicPlan. This is where you likely want a laser measuring device to quickly update the dimensions. Both MagicPlan and Pol圜am allow you to tweak dimensions of rooms, doors, windows, furniture, etc. Polycam also supports photogrammetry where you just take a bunch of photos and it builds a 3D model by interpreting what shape the object could be (I don't know if this is also used in architecture scale things, but it could be interesting for ID projects). MagicPlan has been out for ages and originally just worked off the camera and the accelerometer to help build a floor plan. They both now take advantage of the Roomplan API which Apple introduced in iOS and iPadOS 16. MagicPlan and Pol圜am seem to be the most focused on building a schematic level building model which could be imported into other tools if needed. using a gimbal), but ultimately you'll need to do tape or laser measurements and modify the models that these tools can build, or just model it yourself with the scan as a reference.

There are techniques to improve accuracy (e.g.

The short answer is that the LIDAR and iOS APIs are remarkably powerful, but not 100% accurate. I found this youtube channel has some pretty good walkthroughs (quite literally) of using various iOS apps to scan architectural spaces.
