This is a growing set of tools for bakers which you can use either in your browser from both mobile devices and PCs or you can even install as an application on your device of choice.
If your current platform supports web applications (also known as Progressive Web Apps or PWAs) then you will see Install button above. It should be supported by recent versions of Android, iOS, Windows, MacOS X and Linux. To install to your computer you might need to use Chrome browser.
To install on iOS, you will have to manually click on share icon and then choose Add To Homescreen.
You can also use online version without installing anything. It looks and works exactly the same as installable version. Please note that there is no data synchronisation between platforms yet.
Looks like web apps are not supported on your device at this time. Please use online version instead.
Only a limited set of features is currently available as this project is in its early stages. A lot more things are planned for the future.
Pre-ferment is also known as fermentation starter or mother dough. There are several types of pre-ferments like sourdough, poolish, old dough and barm. This calculator will help you feed, bulk and re-compose your pre-ferments to fit your needs.
Pre-ferment calculator was designed for flour and water based pre-ferments with continuous life cycle. Sourdough is the most well known example of such pre-ferment. But it can also be a poolish or barm which are fed regularly instead of creating from scratch each time.
