Catálogo da Construção m2obras is a free Android app that helps builders, engineers, and anyone involved in construction. It is a portable list of construction materials, tools, machines, equipment, safety equipment, and services, including their average prices. The app also allows users to interact with the developer by reporting any price discrepancies in their region and receiving monthly updates on prices from construction companies, e-commerce sites, and retail stores.

Developed by m2obras / m2 obras, the app features a custom table that is more comprehensive than the SINAPI research. It also has many products with equivalent codes. The app offers other features, such as a glossary of construction terms, a list of ABNT, ISO, NR/MTE standards, architectural symbols sorted by categories, construction events, and search for SINAPI and others.

Users can create customized product lists and export them to Excel, and can even share products via WhatsApp, Facebook, SMS, and email.
