FX CHRONOGRAPH COMPANION · COMING SOON

Every shot,
on your phone.

Switch on your FX chronograph and choose it once. After that it is remembered, and velocities appear as they happen — captured, kept, and organised into strings that still make sense a month later.

On the App Store and Google Play this fall.

01 · VIDEO

The velocity, burned into the clip.

Film the string and each shot's number appears on the frame where it was fired, with a closing card carrying the string's statistics. If the overlay lands a beat early or late, nudge it. One take can cover several strings — including a ladder you split afterwards.

On a Pocket Pro, a rifle rolled by a degree or more gets its cant burned in beside the velocity — the one thing on the frame that would explain a shot that went sideways.

ON FILM 12 of 41 shots in this string are on film

02 · THE STRING

A range day is not one long list.

Tap NEW STRING and the boundary is drawn immediately — no setup screen between you and the next shot. Afterwards you can still split a string at any shot, move a stray round back to the group it belonged to, or type in one the radar never heard.

Forget to press it? A long gap between shots gets noticed, and the app offers a boundary rather than assuming one.

Exclude a shot and say why — fouler, cold bore, squib, bad read, wrong load
Shots the device counted but the phone missed are recorded as missed, not silently dropped
Every string stamps the gun, ammo, zero and air it was actually shot with

BY HAND
TRUE SD, AS SHOTS ACCUMULATE
5 n = 12 60
Your SD of 2.4 m/s is really somewhere between 1.7 and 4.1. Shoot 15 more to narrow it to about 2.0–3.1.
JSB 15.89 VS FX HYBRID 16.20
The 4.1 m/s difference in average is larger than the uncertainty in both. This one is real.
The spreads cannot be told apart at these sample sizes.
03 · STATISTICS

Numbers that admit what they don't know.

An SD from five shots is barely a number. FX Chrono Connect shows you the range the true value is actually in, and tells you how many more rounds it would take to tighten it — so you stop chasing a tune that was noise.

Put two strings side by side and it says plainly whether the difference is real or inside the uncertainty. Extreme spread is labelled for what it is: a figure that grows with shot count and only compares between strings of the same length.

04 · DOWNRANGE

Built on what you measured, not what the tin claims.

The drop table runs from this string's own measured average. A Pocket Pro or True Ballistic reports a ballistic coefficient per shot, and the solver corrects it for the air on the day — the same air it fetches from MET Norway if you ask, or that you type in yourself.

Your zero is held fixed, so today's weather can never quietly re-zero your rifle. Hand the whole load over to FieldSolve when you want a full solution.

05 · THE GROUP

Photograph the target. Get the turret clicks.

Take a picture, mark two points a known distance apart, drop the aim point, and tap the holes. The millimetres are measured rather than assumed — a grid square, a case head, a ruler laid on the target, anything you know the size of.

Out comes the group size and, more useful, exactly what to dial to centre it — in MOA and mil, both, because your scope only speaks one of them.

AND THE REST OF THE RANGE DAY

Everything else you'd otherwise carry a notebook for.

Spoken callouts Each shot read out loud so you can watch the target instead of the phone, with a warning above or below your thresholds. Pick a recorded voice or one of your phone's.
Apple Watch remote The phone is on a tripod at the muzzle and you are behind the rifle. Start a string and arm a recording from your wrist instead of walking back.
Firmware, in the app Updates arrive over Bluetooth with the steps spelled out, the battery checked first, and a plain warning about what not to do while it writes.
Air on the day Temperature, pressure and humidity from MET Norway for the moment you shot, or typed in by hand. Your location is rounded to about 2 km before anything leaves the phone.
Bring your history Import guns, strings and shots from FX Radar. Nothing on the old app is touched, and duplicate guns can be merged afterwards.
Nine languages English, Finnish, Swedish, German, French, Italian, Spanish, Czech and Polish. Statistics keep their English notation, the way the sport writes them.
A daylight palette A real sun mode, not an inversion — warm off-white rather than glaring white, and contrast built for a phone at 400 nits against 80,000 lux.
Your data, out Every string as CSV with notes and both unit systems, plus a single backup file you can keep anywhere and restore on any phone.
PRIVACY

Everything stays on this phone.

No account, no upload, no subscription. Capture, history, group measurement, video and export all work with the phone in flight mode — which is roughly what a range is anyway.

BLUETOOTH The only permission the app needs, and it is only used to hear your chronograph.
CAMERA & MICROPHONE Only if you record a clip. Clips stay on the phone; nothing is uploaded. Everything else works without them.
LOCATION Optional, asked once, and only if you tap to fill in the weather — rounded to about 2 km before it is sent.
COMING SOON

Be there for the first string.
