For the price the developers should not charge extra to export a file, especially when it is so difficult to draw very basic shapes. For the amount of time I spent trying to manually draw a kitchen with bay windows in this app I couldve easily used a desktop based vector app and done my entire house or even hand drafted the whole thing. I like the concept but the execution is poor. For example, even in a rectangular room the app tries to recalculate walls to match the dimensions of other walls so if you have more than a flat wall on one side it will continuously change your inputs until you tweak every measurement to add up correctly. It should allow you to lock a walls measurement so that it cannot change instead of "correcting" something that it isnt supposed to. Also, the measurements are not very accurate. I manually measured every room to ensure accuracy and there was always inaccuracy and sometimes it was over 1 ft. Basically, dont waste your money on this.
