It is an off-line, FREE database meant to be run on PCs. It is fully featured, and has recipe copy-and-rename ability for keeping recipe versions, and a notes window that I use extensively to make recipe revision notes. I like it because the data resides on my own PC where it can be backed up locally, or to a cloud service if that’s your choice. (I never wanted to run the risk of a website closing, and losing all my recipes!) Again, welcome and Happy Mixing!
