Kanau -『つくる人』のための計算メモ帳
材料費をかんたんに計算できます
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
