Real extraction modeling adjusts your gongfu session in real-time, balancing body and astringency across every pour based on how the tea actually tastes.
Three starter approaches to help you calibrate your brewing immediately
Fangul Hode requires no account or network connection during brewing. All computation happens on your device. Version 1.3 for iOS.
Fangul Hode operates on a genuine extraction model rather than static time tables. The app calculates soluble release based on tea class, leaf form, vessel parameters, and water temperature, then adjusts dynamically when you report how each cup actually tastes. This approach accounts for the real variability in tea leaves, water quality, and brewing conditions that fixed recipes cannot address.
All computation runs locally on your iOS device with no server dependency. Your brewing data, leaf cards, and session history remain private and under your control. The app requires no network connection during active sessions, making it reliable for use anywhere you brew tea.
The rescue solver handles mid-session problems by diagnosing symptoms like bitterness, flatness, or excessive astringency, then ranking applicable fixes you can apply immediately. Adjustments propagate through all remaining steeps to maintain balance across the full ladder.
Report each cup along two dimensions: body intensity (heavier, same, lighter) and astringency character (smoother, same grip, grippier). The app translates this into precise parameter adjustments.
Every remaining steep in your session updates in under one second after feedback. The app shows you what changed, which parameter moved, and the reasoning behind the adjustment.
Coverage spans green, white, light oolong, roasted oolong, black, ripe pu-erh, and raw pu-erh. Each class uses distinct extraction curves calibrated to its processing method.
Model how quickly leaves unfurl and release solubles with forms including broken grade, bud berry, twisted, whole flat, rolled ball, and compressed. Leaf structure directly affects steep timing.
Diagnose and fix mid-session problems like bitterness, thinness, flatness, excessive astringency, grassiness, or sourness. Receive ranked solutions applicable in one tap.
Save calibrated teas with their learned parameters. Next time you brew that tea, the session starts already tuned to your vessel and taste preferences, improving with each use.
