I would have to say really cool app some small glitch but I can work around them I did estimate tonight it was very user friendly by that I mean you dont have to take a course to learn how to use it like the 800 dollar estimating program I bought for my pc that I disliked so much I wanted to through my computer away lol this does pretty much same stuff for 29.99 they sell three books inside this app they dont tell you about ontell you buy it for 49.99 what they do for you is give you pricing for labour and material if you put in your zip code or postal code it will give pricing for your area this means you dont even need a brain to do a estimate lol I checked a few things out based on what I no and they are pretty much right on I have only had this app for a short time still have a lot to mess with but so far I really like this app for what it does and I would pay 29.99 for it again thanks for the great app
