It's a great app all in all. It was difficult to calculate quantities on site,when there is no pen and paper. Now it's very easy to calculate anything from diagonal to quantities of concrete, reinforcement, excavation and many many more. Also able to share with my co-workers. Really you did a great job. Very useful as a building contractor and also for my labour.
