The app freezes on you and is slow. If you create a cake and click on a different button to view setting or what not, the cake you just created would disappear and you have to recreate the whole thing again. The dowels placement is incorrect as it only list the number of dowels use for the bottom cake but not the center cake. A real caker know you need a center dowel to keep the cake in place. It doesnt matter if the height of the cake is 2" or 6" the serving size is still the same? How is that possible? Theres also no option to auto calculate dollars per serving. I wouldnt even keep it if I got it for free. What a disappointment, dont waste your money.
