## What is ZephyrAir?

ZEPHYRAIR — Stop Guessing... Start Hitting...

Matches aren't lost on the bench. They're lost in the wind. ZephyrAir turns your live conditions into the exact hold for the next target — so you call it, dial it, and break a clean first-round hit.  From either your Apple Watch, iPhone, or both at the same time!

Built for PRS and NRL shooters who live and die by the wind call.

CALL THE WIND, NOT THE LUCK
- Stream live wind straight from your Bluetooth meter — Calypso, Kestrel, and WeatherDot.
- Per-target wind brackets show your hold from lull to gust, so you know your miss window before the wind even shifts.
- Crosswind, headwind, spin drift, and aerodynamic jump — solved in real time, every sample.

SCAN THE MATCH BOOK. WALK UP READY.
- Photograph the stage briefs at check-in. ZephyrAir reads the stage names, target distances, par times and round counts, and builds your entire course of fire.
- Every match director writes their book differently. On iPhone models with Apple Intelligence, stages that don't fit a familiar layout get read by the on-device model — so the odd book works too.
- Review everything before it lands. Nothing is imported until you say so.
- Up to 50 stages, for multi-day matches.
- Entirely on device. No page, no photo, and no text ever leaves your iPhone.

A SOLVER THAT KEEPS UP
- Dual engines: a fast Pejsa solver and a full point-mass trajectory model.
- G1, G7, and true custom Doppler drag curves (CDM) for honest trans-sonic tracking past 1,000.
- Coriolis + Eötvös, angle/cosine holds for steep stages, and density altitude from the onboard barometer.
- Auto-MV from temperature and BC truing — tune the solver to YOUR data, not the box claims.
- Real ambient air temperature from Apple Weather when you're not running a Kestrel or WeatherDot.

STAGE DAY, HANDLED
- Match timer with par alerts, wrist haptics, and pick-your-voice callouts: Standard, Australian, Western, or Drill Instructor.
- The DOPE Log auto-captures every shot with the conditions behind it — review and re-true after the match.
- Direction-of-Fire compass and moving-target lead for the stages that try to beat you.

ON YOUR WRIST
- A full Apple Watch app — live wind and firing solution at a glance, standalone or relayed from your phone, running the exact same ballistic engine.

CARRY YOUR CARD
- Generate a DOPE card for an NFC e-paper tag — your come-ups, on your stock. No battery, no backlight, no glare.

MAKE IT YOURS
- Classic, Tactical, and Futuristic themes, each with day and night modes for the line or the low light.

Stop guessing. Read it, hold it, hit it.

## Version history (last 5 releases)

### 1.5 — 2026-10-13

Integration with Calypso's new Ballistic Wind Meters

### 1.4.1 — 2026-08-11

Match book scanning is here. Photograph the stage briefs at check-in and ZephyrAir builds your whole course of fire — stage names, target distances, par times and round counts — instead of typing it in at the line.

-AUTOMATED MATCH BOOK IMPORT. Point the camera at each page and review what was read before anything is imported. Nothing is committed until you press Import.

-ASSISTED MATCH BOOK READING. Every match director formats their book differently. On iPhone models with Apple Intelligence, stages that don't match a familiar layout are read 
by the on-device model, so unusual books work too. Nothing leaves your iPhone.

-REAL AIR TEMPERATURE. ZephyrAir now pulls ambient temperature from Apple Weather when no Kestrel or WeatherDot is connected, instead of falling back to the wind meter's fixed placeholder reading.

-TARGET DIRECTION AND INCLINATION THROUGH THE CAMERA. Point the phone at a target like you're taking a picture of it, center the crosshair, and ZephyrAir records the compass bearing and look angle in one capture. Pinch to zoom in on distant plates — a 12-inch square at 400 yards is a couple of pixels at 1x and something you can actually center at 6x. Walk the stage before the clock and every target is logged.

-ANGLE, PER TARGET. Every target now carries its own look angle. A tower stage with a near target below you and a far one above gets the correct incline hold on each, instead of one angle applied across the whole stage.

-TURN THE CROWN, CHANGE TARGET. On the Apple Watch, turn the Digital Crown to move through the targets in your stage. The hold changes instantly — your iPhone sends a solved firing solution for every target in the stage, so nothing is fetched and nothing is waited for. The crown stops at the first and last target rather than wrapping, so you can find the ends by feel with gloves on.

-A GUIDE THAT'S ACTUALLY IN THE APP Settings › Guide now documents every feature, searchable, with a troubleshooting section for the things that bite at a match — a meter that won't pair, a temperature stuck at 50 F, a match book that didn't scan cleanly.
