Understanding how SourFriend learns your starter

SourFriend learns your starter's own fermentation pattern and uses it to predict when your starter will peak. Delayed Mode relies on this to reach peak at the time you set.

What SourFriend needs to learn

• 01

  Fermentation data sent to the app

  SourFriend learns your starter from fermentation data sent to the app. Without the app, Quick Mode and Storage Mode still work, but Delayed Mode uses default timing only.

• 02

  Three completed Quick Mode runs

  Delayed Mode predicts the finish time from your starter's own pattern. Complete Quick Mode at least 3 times first. Until then, timing is based on default values, and peak may arrive earlier or later than scheduled.

• 03

  The full rise and fall

  SourFriend learns your peak by watching the full rise and fall. Don't end Quick Mode at peak. Leave it running until it switches to cooling on its own.

• 04

  The same routine each time

  Use the same flour, the same feeding ratio (starter : water : flour), and the same spot in your home each time. If any of these change significantly, run Quick Mode 3 more times so SourFriend can relearn.

When a session doesn't help learning

• Error 008 is showing: fermentation data isn't being recorded. Fermentation continues, but that session won't be used for learning.
• You use Bluetooth only and the app has not synced for more than 3 days: data left unsynced longer may not be included.
• You stopped Quick Mode at peak, before it switched to cooling.

If Delayed Mode timing is off

Check these four things.

• Have you completed Quick Mode 3 times?
• Has the app synced in the last 3 days?
• Are your flour, feeding ratio, and spot the same as usual?
• Did you let Quick Mode run until it switched to cooling?
