Shooting session
Mark your next end
Tap once per arrow on the target below. Save the end to add it to the current session. You can record the sight adjustment made after each end.
Session comparison
Every saved end is plotted on one target. Each end has a different colour. Turn ends on or off to compare how your groups change as you adjust your sight. The large crosshair is the combined average of visible arrows.
Previous sessions
Save a sight mark
Sight marks are saved separately for each bow setup.
Saved sight marks
Current bow setup
Keep a separate setup for major equipment changes so your old sight marks and sessions stay linked to the correct bow.
