Score stages faster. Build a searchable shooting log. See exactly where you're giving away points. IPSC Quickscore is back. The original launched years ago as a simple way to calculate hit factor and built a following among practical shooters around the world. After time away from the App Store, version 3.0 is a new beginning for that proven idea — rebuilt from the ground up for the way shooters train and compete today. Enter your hits and time in seconds, get the hit factor instantly, save the run, and turn every practice session and match into useful data. FAST, RULE-AWARE SCORING Tap the scoring zones, enter the time, get the hit factor. Track Alphas, Charlies, Deltas, misses, no-shoots, procedurals and steel where the ruleset supports it. Major and Minor power factor are handled automatically for the selected division, and hit factors are calculated to four decimals using truncation rather than rounding. SEVEN SUPPORTED DISCIPLINES Handgun, Rifle, Shotgun, PCC, Mini Rifle, Action Air Handgun and Action Air Rifle, each with its own division list and power-factor logic. MORE THAN A CALCULATOR Every run can be saved, edited and searched. Group runs into matches, separate training from competition, import matches from PractiScore .psc exports, and keep classifier results in the same logbook. Back up your full history to a single readable file whenever you want. SEE WHERE YOUR POINTS GO Turn your logbook into statistics you can act on. Filter by your last 5 runs, last 10 runs, this year, division, matches or training. Track alpha rate, points dropped, penalties, paper and steel performance, your best run in the current filter, and the difference between practice and match shooting. TURN RESULTS INTO DECISIONS Potential shows what a clean run would have scored, and how much slower you could have gone while still matching the hit factor you actually shot. What If lets you change a hit or adjust the time by a tenth of a second and see the effect on hit factor immediately. Test the tradeoff between speed and accuracy before your next run. CLASSIFIERS & STAGE POINTS Compare a run against a reference hit factor, a stage winner, or the level you're chasing. Calculate stage points and percentages, store classifier high hit factors, and see the USPSA classification a classifier result corresponds to. PRIVATE BY DESIGN No account. No sign-up. No analytics.
