Drawdown time reveals your grind.
If it drains too fast, the grind is coarse; too slow, it's fine. The app uses this time to suggest your next adjustment.
What it is
The final phase of a pour-over, when no more water is added and the brewer drains.
Why it matters
How long it takes is your best clue about the grind. Too fast often means too coarse; too slow, too fine — or too much agitation clogging the filter.
In practice
Mark the moment the water is gone. The app compares it with the recipe's target and with how the cup tasted, then suggests what to change next time.
