Wrist Dope vs Precision Rifle Timer

A real ballistic calculator built for Apple Watch first — not a phone app's afterthought. It runs standalone on your wrist; the iPhone companion is a full app, synced. FREE TO DOWNLOAD The full calculator is free on iPhone and Apple Watch. Wrist Dope Pro — a one-time $39.99, no subscription — unlocks wind meters, Field Trueing, Match Mode, scanning, Siri, auto environmentals, live complications, printable range cards, and unlimited profiles — buy or restore on the watch. Accuracy is never gated. WHEN THE SHOT WON'T WAIT No time to thumb through a calculator. Raise your wrist, dial the range, read your hold. Send it. Glanceable and dial-driven, with real math underneath. A SERIOUS ENGINE, NOT A TOY - True point-mass solver with G1/G7 drag models - Coriolis, spin drift, aero jump, and incline compensation - Holds in MIL or MOA — plus velocity, energy, time of flight - Validated against published reference trajectories - Advanced Settings (Pro): toggle each correction LIVE FIRE Dial the range; the solution updates instantly. A color-coded arrow shows wind at a glance; multi-wind previews holds across speeds. The display stays awake on the gun. On the rifle, target angle and cant update your holds live. WIND METERS Connect a Kestrel or a WeatherFlow Tempest or WEATHERmeter from the iPhone or straight from the watch. Its wind, temperature, pressure and humidity flow into your holds. Calypso ultrasonic meters link to the iPhone, readings on the watch, with the wind call relative to your line of fire. A meter the app can't use says why. FIELD TRUEING Correct the solver to what your rifle actually did: true muzzle velocity from a chronograph or a group at distance, then BC on a transonic target. It checks your zero first. Or type your own BC. Load rows show the BC and velocity your holds are solved on. MATCH MODE — STAGE CARD AND TIMER Build a match as stages and targets, then glance-read the active stage's ranges and live holds. Arm the par timer to start on a PACT or Shooters Global beep; watch and iPhone count down together by haptic, beep, or voice. Hunter stages: log each target as you find it, then engage in order. On iPhone, RO mode is one big button. Share a match as a file — the whole squad imports it. AIRGUN READY Eleven airgun calibers, .177 to .72, with pellet-real weights and BCs. SCOPE LEVEL — FREE ANTI-CANT A canted rifle misses wide at distance. Zero the level to your rifle and hold by ear — audio and haptic cues, eyes on target. Pro puts a live level behind Live Fire, the Range Card, and the Stage Card. HIT PROBABILITY AND THE ETHICAL SHOT Lock a target for a real first-round-hit percentage from your velocity SD, group size, and wind call, plus a terminal check for your game. HANDS-FREE WITH SIRI "Hey Siri, Dope for 250" speaks your hold — watch and iPhone. Wind and target by voice, too. POINT-AND-LOCK THE FIELD Aim downrange, tap to lock target; aim downwind, tap to lock wind — read on the shooter's clock face. RANGE CARD ON YOUR WRIST A full dope table, dial to scroll, plus seven watch-face complications: a mini range card, holds, target, density altitude, active load. YOUR RIFLES, YOUR LOADS Build rifle and load profiles on the watch — no phone required. On iPhone, scan a factory ammo barcode and the load builds itself, or pick from a bullet catalog with factory BCs. Export a printable dope card; back up your library to a file. YOUR CONDITIONS, YOUR UNITS Pressure, temperature, altitude, humidity, and wind each toggle AUTO or MANUAL. Metric or imperial, synced across devices. PRIVATE BY DESIGN No accounts, no tracking, no third-party SDKs. Your profiles and readings stay on your device. Weather comes from Apple Weather on request. Built for hunters, PRS shooters, and airgunners who want a first-round-hit hold without unpacking a bag of gear. Runs on Apple Watch Series 4 and later. Wrist Dope is a calculation aid. Always verify your data and shoot safely, responsibly, and within the law.

Precision Rifle Timer is a shooting timer for Apple Watch and iPhone. Pick a duration, shake your watch to start, and hear spoken announcements at intervals you choose — even with your wrist down, the screen off, or Bluetooth ear-pro on. Built for precision rifle shooters and any timed shooting drill where you need your eyes and hands on the rifle-- not on a stopwatch. WHAT YOU GET • Spoken interval announcements (e.g. "30 seconds remaining") • Background audio that keeps playing with wrist down or screen off • Shake-to-start with audible "Engage" cue • Final-second countdown ending with spoken "Time" • Live heart-rate (BPM) and calorie display on the watch during each session • Session history on iPhone — every completed shooting session saved as an Apple Health workout with duration, heart rate, and calories • Toggle to turn session-saving off if you'd rather not record to Health • 1–6 quick-start presets for common timer setups • iPhone ↔ Apple Watch settings sync — configure on whichever device is convenient • Bluetooth headphone audio supported • Adjustable audio latency compensation for tight timing PURCHASE REQUIRED Precision Rifle Timer requires a paid plan to use. After installing, you'll be asked to choose one of: • Monthly — $4.99 per month, with a 7-day free trial • Yearly — $49.99 per year, with a 7-day free trial (saves about $10 vs. paying monthly) • Lifetime — $149.99 one-time purchase, no auto-renewal The 7-day free trial converts to a paid subscription unless canceled at least 24 hours before the trial ends. Subscriptions auto-renew at the end of each billing period unless canceled at least 24 hours before the renewal date. Manage or cancel anytime in iPhone Settings → Apple ID → Subscriptions. Payment is charged to your Apple ID at confirmation of purchase. The Lifetime option is a one-time purchase that does not auto-renew. HEALTHKIT Precision Rifle Timer uses Apple's HealthKit framework on the Apple Watch to give you a real-time view of your effort during a shooting session and to keep a record of each session you complete. With your permission, the watch app reads your heart rate and active energy from Apple Health during a session and shows them live on the timer screen, and saves each completed session to Apple Health as a workout (duration, heart-rate samples, and active energy). You can review past sessions on the "Sessions" tab in the iPhone app. All HealthKit data stays on your device — nothing is transmitted to the developer or to any third party. You can disable session saving at any time in the watch app's settings, and you can revoke HealthKit access entirely through the Health app or iPhone Settings.
