I paid for pro but I don't see any use for this app. No useful instructions or how to guides and examples.Measurements are only mm on the metric side, why not give a user to choose to switch to cm or meters.I tried concrete calculations for a stair. I have no idea why the result number are large like in millions. Then there is no way to see how it is calculated. Because after clicking the detailed result button the screen freezes.Some times it is hard to get back to main menu on the side bar, the back button doesn’t work.I think the app needs detailed instructions for any person to use. But developers are assuming users know most of the things about construction. I for example doesn't know everything but am quick learner with good instructions guides. On the positive side the app has huge potential if developers focus on putting instruction manual and example templates. I am still checking it. So far I found this app is not for prime time.
