Arrow Optimizer app analytics for September 4

Arrow Optimizer turns your practice into data. Log every end, and the app tells you which arrows are actually costing you points, how your sight really moves, and where your equipment needs tuning — no spreadsheets, no guesswork. ARROW OPTIMIZATION Record each arrow's impact by tapping a target photo or entering shots digitally. Every session tracks real vs. predicted score, group size (σx/σy), and World Archery line-cutter scoring that accounts for your exact shaft diameter. Pro tools go further: Quiver Dispersion Tuning shows which named arrows are shooting loose, Arrow Ballistics Data breaks down each shaft's own bias, and the Combination Analyzer tests every possible subset of your quiver to find your tightest, highest-scoring group. CROSS-SESSION POOLING A single session rarely has enough arrows per shaft to trust the numbers. Pool the same named arrow's shots across every session you've logged for a far larger sample, or run an A/B comparison to see whether a new rest or shaft change actually helped — or was just noise. SIGHT CALIBRATION Find your sight's real mm-per-click ratio by shooting a base group, dialing in a known adjustment, and shooting an adjusted group. Every calibration — and every regular practice end where you log a click change — sharpens one shared, ever-improving ratio per distance. A built-in virtual target shows the suggested correction visually. SIGHT MARKS & PREDICTION Save your elevation and windage settings at each distance you shoot, then let the predictor interpolate a starting sight mark for any distance you haven't logged yet. PLUNGER TUNING Sweep plunger tension in steps around your base setting, log a group at each one, and see which tension gives the tightest, best-centered result. EQUIPMENT SETS Save named bow/arrow configurations — arrow type, limb, riser, bow weight, plunger, brace height, tiller, arrow diameter, sight hardware — and tag every session, sight mark, and calibration with the exact rig you shot. Switch between an indoor and outdoor setup, or two different bows, without losing track of which sight settings belong to which. PROGRESS Watch your practice volume, group tightness, and round scores trend over time, across every distance you shoot. YOUR DATA, YOUR CONTROL Back up every session, calibration, target photo, and equipment set to iCloud Drive or your device, and restore it anytime. Available in English, German, Ukrainian, Spanish, Korean, Turkish, Portuguese, Russian, and French. Free to log sessions, calibrate your sight, and track sight marks. Unlock Pro for the full optimization engine: Quiver Dispersion Tuning, Arrow Ballistics Data, the Combination Analyzer, and cross-session A/B comparison — the tools that find the fraction of a millimeter separating placings at competitive levels.
