Ignore all these ignorant people.. They simply dont know how to use the app to its advantage, look at the video to know how to use the app and you will love it ! This has to be the best app for juicing !! Has a list for your groceries, customizes your juice on what kind ingredients you choose and even has info on how to prepare your veggies/fruits and so much more ! Only downfall is wish they would add on the shopping list an option to multiply your servings and go off of that but nonetheless its perfect !
