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.

Verdict
The clearest difference is rating: GAMMA AR at 4.6 against BLK2GO Live's 4.0. GAMMA AR also leads on update cadence (every 2 weeks vs every 5 months). BLK2GO Live's advantage is review sentiment (100% vs 86%) and iOS requirement (12.1 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
GAMMA AR holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 8 and 4 respectively. Written reviews complicate that: 86% of GAMMA AR's written reviews are positive against 100% of BLK2GO Live's, so the app with the better star average is not the one people write more warmly about.
GAMMA AR ships an update every 2 weeks, BLK2GO Live every 5 months. The most recent releases landed on September 15, 2026 and August 16, 2026 respectively.
