Diagnosis
It finds your weakest fundamental
The Coach reads every press across your sessions and pinpoints what's actually holding your score back. Not a guess, a pattern in your own data.
Dry-fire · Live-fire · Sport shooting
Read the shot
before it breaks.
SteadyArc measures the micro-motion of your hold and trigger press, scores every rep with a three-part score you can't game, and turns your own data into the next drill. Start free with just your phone.

Data

01 · The demo
See it in motion
From trigger to score to coaching cue: the whole loop, captured from the real app.
02 · The score
One number.
Three ways to earn it.
Most trainers hand you a single score you can chase by gaming one variable. SteadyArc blends three independent fundamentals and shows every one of them. Tighten one by sacrificing another and the composite tells on you.

03 · The loop
Four steps between you and a cleaner break
01
Capture the motion
Mount the SteadyArc sensor, or start today with just your phone. It catches the smallest movement of your hold and press, live and wirelessly, as the shot breaks.
02
Score it honestly
Every press is broken into hold stability, press movement and smoothness, then blended into one composite you can't game by faking a single number.
03
See the tendency
A crosshair trace shows exactly where the muzzle drifted as the shot broke (down-left, high-right) so you fix the cause, not the symptom.
04
Train with intent
Drills and guided courses turn raw data into a plan. Chase pass thresholds, build consistency, and watch your 30-day trend climb.
04 · Shot grouping
Watch your group tighten
Every press lands on a crosshair target plotted from real muzzle motion. Consistency, average, and a plain-language tendency tell you whether you're drifting, and which way.
- Live group scatter
- Per-session consistency (±)
- Direction-of-drift readout
05 · Progress
Proof you're getting better
Sessions are saved on-device and charted over time. Your best, your recent average, and a trend you can show your coach. All of it yours to keep and export.
- Session-average trend
- Personal bests
- Own-your-data export
Also in every session: shot trace · par timer · recoil recovery · split times · coaching cues · plain-file export
06 · The AI Coach
A coach that shows its work
The reason to go Pro. The AI Coach watches your fundamentals across every session, tells you what's slipping and why, and prescribes exactly what to work on next. Then it keeps adapting as you improve.
Why
It explains what's going wrong
Plain-language cause, tied to the motion behind it: pre-ignition push, a hold that won't settle, a break that isn't smooth. You learn the why, not just the what.
Prescription
It tells you what to train next
A concrete next step, the drill or pack built for that exact fault, so every session has a purpose instead of just chasing a number.
Longitudinal, not one-off
The Coach remembers. It tracks how each fundamental moves week over week, points you at the pack that targets your current weakness, and shifts focus as your weak spot changes. Coaching cues run on-device, so they keep working with no signal at the range; optional AI narration uses the network when it's available and falls back gracefully when it isn't.
07 · Structured practice
Drills with a pass line.
Courses with a path.
Open practice is free forever. Pro unlocks guided courses that sequence drills with pass thresholds, so you always know what to train next and when you've earned the next rung.

10 · The dedicated sensor
The sensor is coming.
Be first in line.
You don't need it to start: the SteadyArc app works on your phone today, free. The dedicated sensor is a later upgrade, a purpose-built, high-rate motion device that mounts to your frame or rail for the most precise capture, at home for dry-fire and at the range for live fire. Join the waitlist and you'll be first to claim one from the opening batch.
Planned specs
- IMU
- High-rate motion sensor
- Wireless
- Bluetooth Low Energy
- Power
- Rechargeable LiPo + smart battery gauge
- Controls
- Single-button power
- Mount
- Frame or rail mountable
- Onboard
- On-device capture, syncs to the app
Specs are targets and may change before launch. No payment now — waitlist only.
Do I need the sensor to start?
No. SteadyArc runs today using your phone's built-in motion sensors: start training and scoring reps for free. The dedicated sensor adds even more precise, frame-mounted capture when you want to go further.
Is this for dry-fire or live-fire?
Both, with the same app and the same coach. Exercises come in dry-fire and live-fire flavors, and you tag each session by mode so scoring reads recoil correctly. Train at home with dry-fire, then take it to the range for live fire.
How is the score calculated?
Each press is broken into three independent fundamentals (hold stability, press movement, and smoothness) then blended into one composite. Every component is shown, so the number reflects real fundamentals rather than one gameable metric.
Who owns my data?
You do. Sessions are stored on your device and exportable as plain files. Pro adds optional cloud backup, but your data is never locked in or sold.
What does Pro cost and can I cancel?
Pro is $5.99/month or $49/year with a 7-day free trial, billed through Lemon Squeezy on web. It unlocks the AI Coach, advanced analytics, and every exercise pack. Cancel anytime from your dashboard. Prefer to pay once? Buy individual exercise packs for $3.99 each and keep them forever.
Does it work offline, at a range with no signal?
Yes. Capture, scoring, drills, history, and on-device coaching cues all run with no network. The only things that need a connection are buying, syncing your scores, and downloading new content — never the training itself.
What platform is the app on?
Android first, available now. A web dashboard handles your account, history, and billing. iOS is on the roadmap for later.
When does the sensor ship, and what's in the box?
We're not promising a ship date. The app already does the job on your phone, so the sensor is a later upgrade rather than a prerequisite. When it's ready the kit centers on the dedicated motion sensor with a frame/rail mount, a rechargeable battery, and a single-button design. Join the waitlist to be first in line for the opening batch. No payment now.
