How is CutJournal AI Different?
Most weight trackers just plot a number on a graph. CutJournal AI goes further.
Basic Weight Trackers
- Track scale weight only
- No body composition insights
- Can't distinguish fat loss from muscle gain
- Discouraging when the scale doesn't move
CutJournal AI
- AI estimates body fat from your photos
- See body composition changes over time
- Understand recomposition, not just weight loss
- Visual progress even when the scale stalls
