Building Block Calculator is a free Android app designed to help builders and contractors calculate the cost, number, and weight of building blocks needed for their construction projects. The app's main feature is the ability to enter additional presets in the program settings, such as the price of blocks for 1 cbm or a piece, volume of one pallet, and weight of 1 block, which allows for advanced calculations. Additionally, the program can take into account the presence of window and door openings when calculating.

One of the unique features of the Building Block Calculator is that it rounds the number of pallets to an integer and makes an alternative calculation based on this, which is useful when buying blocks from a factory where it is not possible to buy building blocks separately. Builders can also save their calculations in the memory of their smartphone or share them on social networks, messengers, or save in the cloud. The app is a convenient tool for builders and contractors looking to streamline their calculations and save time on their construction projects.
