TargetLog measures shot-group diameter across sessions so the thing that actually matters — consistency — is the thing you can see improving.
- Group diameter, tracked
Automatic measurement of your shot spread, session over session.
- Score progression
See your average climb alongside tighter, more repeatable groups.
- Shot distribution
Histograms reveal whether you're pulling left, dropping low, or scattering.
