Meal journal with photo intelligence
Detects likely foods from meal photos and lets you correct ingredients.
CGM + CKM aware · early access
See how food changes your metabolism.
Metabolog combines glucose, ketone, meal, and lifestyle data so you can understand your metabolic response after every meal.
Metabolog is for informational and wellness insights only and is not a substitute for medical advice.

The gap
Metabolic data is powerful. It is also fragmented.
- 01
CGM apps show glucose, but rarely explain meal context.
- 02
Ketone data often lives somewhere else.
- 03
Manual fingerstick and ketone meter readings are easy to lose.
- 04
Food logs are tedious unless they fit into daily life.
- 05
Metabolog brings those signals together around the meal.
How it works
From the moment you eat, to the pattern you learn.
01
Log what happened
Snap a meal photo, speak what you ate, or enter it manually.
02
Add your signals
Use CGM/CKM data, Libre imports, ketone files, or manual glucose and ketone readings.
03
See the response
Review glucose rise, ketone suppression, GKI, recovery, and meal impact.
04
Learn your patterns
Spot foods, timing, and habits that consistently move your metabolism.
Capabilities
Designed around the meal, not the metric.
Eight focused capabilities that turn fragmented signals into a single metabolic timeline.
Voice meal logging
Say what you ate and log it quickly without turning it into a data-entry session.
Manual glucose & ketone readings
Add fingerstick glucose or ketone meter readings when sensors are unavailable.
CGM and CKM response analysis
Connect meals to glucose curves, ketone changes, GKI, and recovery.
Apple Watch sync
Keep recent glucose and forecast state available on your wrist.
Privacy-aware data handling
Designed for sensitive metabolic data with local-first storage patterns where possible.
Personalized meal feedback
Mark false positives and corrections so meal detection gets better over time.
Forecasting readiness
Understands when there is enough recent data to generate useful forecasts.
Manual readings
Not every useful reading comes from a sensor.
Metabolog lets you manually enter glucose and ketone readings, so fingerstick checks, blood ketone meter readings, and sensor gaps still become part of your metabolic timeline.
