There’s now an app for that! Oregon State University has created a free app for your mobile device for instructions on canning vegetables, fruits, meats and fish.
This app is intended for people with previous canning experience. It has reminders for essential steps in the canning process. It also includes altitude adjustments and a built-in timer for the product you are canning.
This free app is available for Apple and Android devices. Learn more at: https://catalog.extension.oregonstate.edu/pnw689.
