GAMMA AR: Augmented Reality for Construction Site Management GAMMA AR is an application designed for monitoring construction sites. It utilizes augmented reality technology to overlay 3D Building Information Models (BIM) on construction sites using smartphones or tablets. With GAMMA AR, site managers, facility managers, craftsmen, and other stakeholders involved in the construction process can walk through the site and compare real-world conditions with the planning information contained in 3D BIM models. GAMMA AR enables the visualization of 3D BIM models before and during the construction process, thereby fostering a better understanding of the planning, preventing errors, and reducing construction costs. This enables site managers and planners from various disciplines (HLS, architecture, etc.) to collaborate on the construction site using the BIM model, preventing collisions and resolving ambiguities before they lead to errors. Additionally, GAMMA AR allows for the direct detection of errors within the BIM model, enabling adjustments to be made during the planning phase, preventing errors, and ensuring comprehensive monitoring of construction progress. Is GAMMA AR for you? GAMMA AR allows you to connect various software systems such as Autodesk, Procore, and BIMCollab. Construction site managers benefit from GAMMA AR by avoiding errors and eliminating the need to interpret 2D plans. Facility managers can report errors or make adjustments directly in the BIM model via GAMMA AR and transmit this information to other stakeholders involved in the construction process. GAMMA AR is an easy-to-use, intuitive tool that can be applied directly without requiring any training that could increase the cost of implementation. For construction companies, GAMMA AR offers significant benefits: entire departments can be relieved of the burden of communicating via 2D plans, which is no longer necessary. GAMMA AR establishes digital communication channels between the construction site and the office. Using BIM360 or Autodesk Construction Cloud (ACC)? Simply sign in with your Autodesk account, import your IFC, REVIT, and NAVISWORKS models into GAMMA AR, and synchronize your issues with BIM360, ACC, Procore, or BIMCollab. Summary Avoid Errors: Plans on-site are cumbersome and prone to errors! For many tasks, it is faster and safer to review the plans directly on a tablet and compare them with real-world conditions. By working digitally on tablets and smartphones, the reliance on paper plans is significantly reduced, thereby lowering the risk of obsolete information and redundancies. Sync Models and Notes with Your Office: With GAMMA AR, you can send issues directly from the construction site to the office. Each comment is directly linked to a building element or room during site inspections. With this location reference, new information is immediately integrated into the building model. This simplifies documentation and improves communication, as comments are clearly and unambiguously conveyed.

The FieldAR mobile app enables your entire project team to effortlessly view the latest BIM/3D design models overlaid onto your real-world construction site using precision augmented reality. FieldAR’s primary objective is to provide a central source of truth for quality assurance, quality control, and the precise locations of installed systems and equipment at active or completed construction sites. With FieldAR, users can visualize BIM/3D models overlaid onto real-world construction sites with a simple, single-tap operation, making it easy for even non-tech-savvy field staff to see the exact locations of designed building system elements. BIM/VDC Managers can leverage the FieldAR plugins to easily upload and update models directly to the FieldAR mobile app, ensuring that the entire team is working with the most current information. Additionally, markups captured by team members using the mobile app on-site can be viewed back in the BIM platforms through the FieldAR plugins, creating a seamless workflow of information between off-site BIM management and the construction site. FieldAR empowers your team to save money, reduce re-work, and optimize project schedules while enhancing productivity and collaboration. FieldAR supports 8 languages: English, Spanish, French, German, Japanese, Polish, Russian, and Chinese (zh-Hans). Core AR features: -Single-tap model loading with automatic alignment to the real world -BIM/3D models are automatically downloaded and aligned when users scan QR code targets at your physical jobsite -AR Markups tool that enables your team to flag issues while on site -Markup data can be viewed in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -AR Measurements tool that can measure model elements and/or real world elements -Built-in camera for taking photos and recording video -Mesh scanner for capturing meshes of the real world -Scanned meshes can be added to markups, and are automatically aligned to the model -Scanned meshes can be viewed in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -AR opacity adjustment to see more/less of the 3D model or the real world -AR sectioning tool to “slice” the 3D model -BIM/3D model details viewer for viewing model element details -Model elements can be hidden, isolated, and highlighted -AR floor plan mini-map that can be used to visualize where the user is at the jobsite -AR Wireframe mode to see the wireframe of the model -AR occlusion culling that will allow real-world elements to show through the model For BIM/3D model managers: -Upload/update 3D models directly from the mobile app or FieldAR plugins for Navisworks Manage and Revit -Advanced 3D model viewer for viewing the model when away from the jobsite -Generate custom-branded QR code targets that can be printed and installed at the physical jobsite -QR code target placement tool in AR -Cloud-based spatial anchor placement tool that helps automatically align the model when users view the model in AR -View markup sketches, details, mesh scans, and conversations directly in the mobile app and in the FieldAR plugins for Navisworks Manage and Revit -Upload floor plans, and locate models on the floor plan AR Project Management: -View/edit your full project list in your Dashboard -Navigate models within each project -View all project activity, i.e. model updates, markup comments, etc. -Easily create new projects and upload models from the mobile app

Verdict
The clearest difference is rating: FieldAR at 5.0 against GAMMA AR's 4.6. FieldAR also leads on iOS requirement (13.0 vs 16.0). GAMMA AR's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (8 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
FieldAR holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GAMMA AR has 8 ratings behind it against 1, so its average is the more settled of the two.
GAMMA AR ships an update every 2 weeks, FieldAR every 2 months. The most recent releases landed on October 19, 2026 and October 20, 2026 respectively.
