Kanau is a calculation notepad for all creators/crafters. By creating a project and adding items in the app, you can easily total the materials' cost. How much does it cost if I use two of a ten-pack? How much does it cost if I use the only 30ml of a 180ml liquid? You can get the answer straight ahead by easy steps. You can also enter work hours, add them up, and convert them to cost by hourly rate. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
