Signal State
Near PeakRise velocity is easing while jar height is still climbing, a strong cue that the dome is nearly there.
Features
Soft signals, clearer decisions.
Built for bakers who would rather mix on instinct than hover over a jar. Leaven keeps the fermentation story visible from first rise to peak.
Real-time Monitoring
Stream rise height, temperature, humidity, and starter motion from a warm, always-on kitchen dashboard.
Fresh sensor snapshots every 15 seconds.
Peak Detection
Track fermentation curves as they build, flatten, and crest so you know exactly when your starter is ready.
Forecasted peak windows with confidence cues.
Smart Alerts
Get timely nudges before the top of the rise, not after it has already slipped away on the counter.
Gentle notifications tuned to your bake routine.
How It Works
Three calm steps to better timing.
The experience stays simple on purpose: set it down, glance at the curve, and let the alerts tell you when the starter is at its most useful.
Place the sensor
Set your starter jar on the monitor and pair it in a few guided taps.
Watch the curve build
Leaven reads rise data continuously and turns it into an easy fermentation timeline.
