One scorer, every event on your calendar

ISSF shooting spans targets that could not be more different: a 0.5 mm ten ring at 10m, a 500 mm black at 300m, rapid-fire pistols that vanish in 4 seconds per series. What they share is the scoring logic — a shot is worth the highest ring its hole touches, gauged against the official geometry of that event's target.

TargetLog applies exactly that logic to a photograph. Pick the discipline, shoot, photograph the target, and the app maps every detected hole to the correct ring layout — decimal sub-rings for air rifle, integer rings and inner tens for air pistol qualification, the larger formats for 25m, 50m and 300m events.

How does ISSF target scoring work?

Every hole scores by the highest ring it touches, from 1 to 10. Qualification uses whole numbers; finals use decimal scoring that splits each ring into ten parts, to a maximum of 10.9. The full walkthrough is in how ISSF scoring works.

Rules baked in, not approximated

  • Correct ring geometry per event. Each supported discipline uses its own official ring boundaries — a 25m precision target is not scored like a 10m card, and the app never pretends otherwise.
  • Inner tens where they exist. Counted automatically, per card and per session, for the events where they decide ties.
  • Decimal granularity. Air rifle and finals-style scoring use the decimal sub-rings; qualification-style pistol scoring uses integers. The app follows the event.
  • Shot-level history per discipline. Sessions are logged by event, so a season of 10m cards, 25m precision and 50m free pistol stays separated and comparable within each discipline.

Why rule-accurate practice scoring matters

Training against wrong numbers is worse than training against no numbers. If your practice scorer is generous — a finger-width estimate, a mis-scaled app — you build a false baseline that collapses at the first official match. Scoring your practice cards with the real ring geometry keeps your training data honest and your progress real.

That's also why TargetLog is explicit about its limits: it is not a certified match-scoring system, and official results will always come from electronic targets or judges. It is the scorer you carry for every card that doesn't get scored officially — which is most of them.
