Archer's Portal vs ArrowForge

Archer's Portal is the precision toolkit for serious archers - tournament shooters, 3D leagues, and Western bowhunters alike. Built on the math, designed for the field. TAPE BUILDER Build pixel-precise sight tapes from your real measurements. The physics engine - an RK4 ballistic integrator with explicit air density - extrapolates clean, smooth marks past your last measured yardage. No more guessing what the dot will hit at 80 when you only shot out to 60. • Brand presets and full custom mode • Per-row mean, standard deviation, and outlier flagging • Optional bow + arrow profile for atmosphere-aware extrapolation • Color bands, custom cap logos, PDF export verified against a credit-card scale box • Pinch-zoom preview, share sheet to AirDrop or print BOWS Catalog every bow you shoot. Peep height, sight radius, draw length and weight, chronograph speed, axle-to-axle, let-off. Tag your daily driver, your backup, your hunting rig. ARROWS Full component breakdown with live front-of-center (FOC) computed as you edit. Shaft, point, insert, nock, fletching, wraps - change any value and watch your balance shift in real time. SPINE CALCULATOR Easton-style static spine recommendation with all the standard adjustments - arrow length, point weight, cam aggression, release style. Quick, conservative, and shows its math. FOC CALCULATOR Standalone what-if for testing builds before you cut anything. SCORECARD Multi-player round scoring built for ASA, IBO, Body, WA 3D, NFAA Field, or any custom system. Pick a scoring matrix, add players, tap the rings shot-by-shot. Bonus shots (twelves, fourteens, custom point values) are supported. Live leaderboard. PDF export at the end. WHAT IT DOESN'T DO No accounts. No cloud servers we control. No analytics. No ads. No tracking SDKs. Your data lives on your device. If you sign into iCloud, it syncs to your other Apple devices through your own private iCloud Documents container - we never see it. BUILT BY ARCHERS, FOR ARCHERS Made with feedback from competitive 3D shooters and Western hunters. Tested against real-world sight tapes from Dialed Archery. Ships with the physics-based engine, not lookup tables.

Stop guessing. Build the perfectly matched setup before you buy the parts. Max your effectiveness. ArrowForge turns the guesswork of your bow and arrow setup into clear, ballistics-grade answers. Enter your bow and arrow (or Pro users get AI recommendations), and instantly see whether your build actually works — spine, FOC, speed, kinetic energy, and lethal range — with the math explained in plain English. Experiment with modifications before you buy the parts. ArrowForge Pro is an auto-renewing subscription: $6.99/month or $39.99/year. Payment is charged to your Apple Account at purchase. It renews automatically unless turned off at least 24 hours before the period ends; manage or cancel anytime in Account Settings.

DIAL IN YOUR BUILD — FREE • Dynamic spine check against a multi-brand consensus — know if your specs is right before you buy • FOC, GPP, GPI, total weight, and a calibrated arrow-speed estimate • Kinetic energy & momentum at the bow and downrange • Drag-aware field-ballistics solver with an uphill/downhill shot-angle dial • Sight pins, holdover, and pin-gap planning • Pursuit Effectiveness — your lethal range by game class (deer, elk, toughest game) from real KE + momentum thresholds • Build Match Score weighted to your hunt and goal • Every number comes with a plain-English explanation of why it matters ARROWFORGE PRO — AI + THE MATH • AI bow & arrow spec lookup — type a model, get the specs • AI Arrow Recommender — purpose-built archetypes for your setup • AI Sanity Check, Build Plan, and tuning insights • The exact formula AND your step-by-step calculation behind every number AN INFORMED SECOND OPINION — NOT A SHORTCUT ArrowForge is a sanity-check, not a substitute for proper tuning by qualified bow technicians. It defers to your bow technician on spine, draw length, and setup safety, and it never tells you to take an unsafe shot. Always verify on the range and with a qualified pro before you hunt. Core calculations work offline. No ads. No data selling.
